Abstract
In architecture a native of Iran is one of the principles of designing urban spaces people heir. Iranian architect has always been the human needs and demands into consideration. The architect of the past based on the desired climate space architecture in order to provide the human comfort design. Climatic conditions, along with other environmental factors, including the most important factors in the formation of the urban tissue. According to the characteristics of the architecture of the hot and dry climate of the burning sun of Iran and high thermal grade set, one of the last in the direction of the architect prolegomena ghosting in designed and produced Gzarha, awning. The awning are enable in the alley and Gzarha, which is part of Ford’s baths and climatic elements as well as the optimum biological requirements, in addition to making in retrofitting buildings of both sides of the Gzarha role. Unfortunately, nowadays in Iranian architecture, awning, to have been forgotten and the urban tissue of the awning or totally destroyed or have been to have been abandoned. With the recognition and evaluation of the architectural had knowledge of the geometry of the design knowledge can be structural elements of the ‘ climate-and once again, and also can be found in contemporary design and the urban tissue of the upcoming hot and dry climate of these special elements of the template. Between the geometry and the architecture of Yazd Fahadan quarter awnings body, and there is significant direct relationship. Based on the literature reviewed thus far, little research on the subject of the typology of Iranian awning and reviews of this climatic elements-from the perspective of structural knowledge of geometry.

More research on the concept of the awning as the climatic element, check its stability in the amount of Gzarha and typology in the cities of Isfahan, Yazd, Kermanshah and because Shushtar. This document first geometric features of the architecture of the neighborhood, Yazd Fahadan awnings case is assessed. In the present study research methodology in terms of the objective applied-and in terms of the fundamental, method, method of inductive reasoning. The data field of a library, and on the left-hand tyranny. As well as the method of the analysis of qualitative data, quantitative methods-. After the library studies about the awning and its species, the hot and dry climate, awning, city of Yazd. Given that the neighborhood is one of the valuable historical neighborhoods Fahadan city of Yazd and had the original on the awning has chosen this neighborhood Neighborhood and 25 examples of this continuous awnings precious historic texture of the randomly selected, shooting data and to invoke the method of inductive analysis of the entire case apart. In this study, 256 Motalah sample random item selection and expressed. Between the geometry and the architecture of Yazd Fahadan quarter awnings body, and there is significant direct relationship. Based on the literature reviewed thus far, little research on the subject of the typology of Iranian awning and reviews of this climatic elements-from the perspective of structural knowledge of geometry.

Research Findings
This article focuses on the impact it has had on the geometry and shape of the neighborhood architectural desired awning case analysis. This research was completed in line with the previous research and reviews of historical proportions awning Fahadan quarter of Yazd. Based on the review conducted, became apparent between the geometry as a factor influencing the Fahadan quarter of Yazd awning architecture machines. The awning case study in terms of the geometry of the plan and the facade proportions and comply with the Iranian. The planning rectangular Fahadan quarter of Yazd awning is complete to the ratio of 1.73 and the ratio of that follow. This was evident in the analysis of the maximum number of the awning case reviews in terms of placement location in the middle of the pass. The largest number of covering arch with arch, and most of these Mazh awning in the direction North-South geographic have been drawn. As mentioned, an important element of the native architecture awning and climate are considered that Iran nowadays knowledge making it to oblivion. With this special climatic elements can be revived by the ancient native patterns as well as in the construction of the urban tissue and forming of new concepts that are of interest. In this study, the historical neighborhood of awning plan and valuable knowledge from the perspective of Yazd Sahadan geometry and rectangular proportions of Persia were analyzed. In future research can be found other than to work in Iran and other Persian architecture in the structure and architecture of the climatic elements-structural (awning) about the investigation. This test also can be used for other cities and places of historical texture of Yazd.

Abstract
In this article, the production systems of lithic artifacts during the Neolithic period of eastern Mazandaran has been studied based on the 2020 excavation of Touq Tepe using a descriptive-analytical approach. Examining the technology, typology, and the effect of subsistence on applying methods of technologies and studying the production methods of various artifacts were among this research project’s most important questions and aims. Touq Tepe is located in the central district of Neka, near Hotukosh mountains, one of Iran’s most important Chert sources. These artifacts were not locally made at the site and part of the production sequence took place elsewhere. Since there was no blade core in the assemblage, it seems that the blades came to the site in already-prepared form and mostly retouching and finalizing processes of the debitages were done at the site. Evidence such as a large striking platform, dual striking bulb, and dented striking bulb indicates that the technology used in the Touq Tepe lithic artifact was either direct percussion with a soft hammer or indirect percussion. Some of the most important characteristics of the assemblage are the abundance of over-flake and notched-denticulated tools and the shortage of scrapers (thumbnail and geometric) and tools with sickle gloss. The lithic industry of Touq Tepe resembles the Mesolithic stone industry of Komishan Cave regarding its technological composition. The production method of the stone artifacts in the Neolithic was likely a continuum of the Caspian Mesolithic period. The subsistence economy has a direct effect on the production method of artifacts. Our study showed that due to the high environmental capacity of the studied area in providing prehistoric societies with food, there was no dramatic change in the typology and technology of lithic tools on the site despite the change of the subsistence towards food production.

Introduction
In the process of Neolithization, and then during the Neolithic period, the hunter-gatherer subsistence transformed into domesticate-farming (Bar-Yosef & Meadow, 1995; Barker, 2006; Hole, 1984; Bar-Yosef & Belfer-Cohen, 1992). With those mentioned transformations came a metamorphosis in lithic tools technology. Thus, technological and subsistence developments are two fundamental issues in Neolithic research.  
Proper archaeological research has shown western and southwestern parts of the Iranian plateau as one of the major zones of Neolithization. Thus, these regions have absorbed most of the research interests regarding the Neolithic period (Roustaei, 2014). Meanwhile, most of the reports on eastern Mazandaran are about Mesolithic sites as far as there is little known about this period even in sites with in situ Neolithic layers like Kamarband (Belt) Cave (Jayez, 2012: 284). Therefore, one of the important aims of this article is to deal with this period through new archaeological findings in Touq Tepe, a site located in Neka Plain, and study the technology and typology of its lithic artifacts.
The current research has studied the technology and typology of stone artifacts from the Neolithic layers of Touq Tepe and the subsistence of its inhabitants, which is useful to clarify the processes of change in the technology and typology of artifacts from the Mesolithic to the Neolithic period and open the way for future studies. Given the proximity of the site to one of the largest and finest Chert sources in Iran, the artifacts were studied for their raw material so a logical relationship between raw material abundance and the diversity of lithic artifacts could be established. Naturally, larger and thicker tools were used for rougher tasks. The production methods of these artifacts were mostly direct and indirect percussion. 
In this study, newly-found lithic artifacts from Neolithic layers of Touq Tepe were first studied separately for classification, typology, sourcing, and investigation of the Neolithic subsistence economy. The findings were classified into four types: tools, debitages, cores, and natural stones. Eventually, the results were compared to published data of the nearby sites from quantity and diversity points of view to establish a foundation for general knowledge about subsistence in the Neolithic period. 

Disccussion
Totally, 348 stone artifacts were recovered from Neolithic layers of Toq Tepe. This assemblage has 6 cores (1.72%) including 3 flake cores, 2 microblade single-side cores, and 1 irregular mixed core. A total of 259 (74.43%) artifacts are simple debitages including 135 flakes, 43 blades, 15 microblades, 2 burin spalls, 35 chips, and 27 debris. 81 (23.28%) tools consist of retouched (31 retouched flakes, 24 retouched blades, and 10 retouched microblades), notched tools, notched-denticulate tools, backed microblades and multi-functional tools and 2 (0.57%) naturally occurred stones. 
The places of flake and microblade on cores are highly irregular and their exterior angles are less than 90 degrees. The blades and microblades have mostly irregular ridges and a profile with low curvature. The ventral surfaces are not completely flat and have waves on them. The thickness of the striking platform in blades and microblades is quite low and flakes with a thick striking platform and prominent striking bulb with dents over the bulb are also rare. In this assemblage, dented striking bulbs are more common in flakes, blades, and finally microblades, but completely absent in burins. 
The flakes were rarely made using direct percussion and in the majority of cases they were produced using direct percussion with a soft hammer or indirect percussion. All the blades were made using direct percussion with a soft hammer or indirect percussion. In microblades, considering the faded striking bulb and their paralleled edges, it is probable that the pressure technique was used Although no pressure microblade core was found. All the lithic artifacts of Touq Tepe were made out of Chert with various color spectrums but mostly from light to dark brown. 

Conclusion
The number of simple debitages is far more than debitages turned into tools and those that turned into tools have larger dimensions and irregular retouches. Based on the comparison of the average sizes of the tools made over the flake blank and the simple debitages on the flake blank and the high ratio of chips to the tools, it can be concluded that the process of making and converting simple debitages to tools was taken place in the site and according to the immediate needs thus most of the retouches are irregular. Scrapers were mostly made over flake blanks and have denticulate or notched-denticulate retouches that do not need any special pre-design. 
The lack of blade cores and the low percentage of blade’s simple debitages support this hypothesis that the blades were imported into the site in already-prepared form and then retouched at the site. In the Touq Tepe lithic industry, there was an emphasis on flake production due to the availability of raw materials. The technical evidence over the debitages of stone artifacts of Touq Tepe confirms that debitages were detached from cores using direct percussion with a soft hammer or indirect percussion.

Abstract
The potential vulnerability of primitive societies to natural disasters, such as droughts, floods, and famines caused by climate change, is an important issue that requires careful study. The main aim of this research is to investigate the possible effects of ancient environmental and climatic changes on Bronze Age settlements in southeastern Iran, as well as the main dynasties that ruled Iran based on archaeological and historical evidence of territorial boundaries, economic and political prosperity. Adaptation of climatic and cultural changes in the southeast of Iran can provide valuable information for researchers. In this regard, this article aims to answer the question of whether climate change has affected the ancient societies of Jiroft, and to what extent climate change has affected the economic prosperity and political influence of the ruling dynasties that have affected Iran. In the present study, using a combination of geochemical and pollinological indicators, we examine paleoclimatic changes of the southeastern plateau of Iran during the past 4000 years. Significant agricultural activities existed between 3900 and 3700 years ago in the southeast of Iran during moderate climatic conditions. Dry conditions with increased dust prevailed over the region from 3300 to 2900 years ago. Wet conditions from about 2900 to 2300 years ago facilitated extensive agriculture and coincided with the flourishing of regional governments such as the Medes, Urartos, and Mannas in the western Iran, and after that the Achaemenid Empire throughout Greater Iran. The decline of the Achaemenid Empire coincided with the beginning of a dry period that made agriculture less prosperous in Jiroft for nearly 200 years. Southeast Iran experienced humid conditions between 1550 and 1300 years ago, which coincided with the economic prosperity of the middle to late Sassanid Empire.

Introduction
This study aims to reconstruct the paleoclimate history in southeastern Iran by tracing the landscape changes and climate fluctuations since the Late Bronze Age and their impacts on human societies based on palaeo-environmental analysis of a wetland system. It will further evaluate the possible impacts of climate change on major ruling dynasties of Iran since the Late Bronze Age. An example of the latter would be following the territorial extent of major ruling dynasties from historical records, which would have been quintessential to society’s prosperity and growth coeval to favorable climatic conditions for agriculture and trade, and the development of city-states. The study involves a multi-proxy palaeo-environmental reconstruction using geochemical, and paleoecological proxies in a 250-cm long peat sequence near the archaeological complex at Konar Sandal near Jiroft, covering the last 4000 cal yr BP. The different proxies suggest changes in elemental concentrations, stable isotopes, and pollen records. 

Materials and methods
Palynological analysis were done in Thirty-five subsamples at intervals of 1-10 cm at the Institut Méditerranéen de Biodiversité et d’Ecologie, Aix-en-Provence, France by procedure described by Gurjazkaite et al. (2018). 

Geographical setting
Konar Sandal (25 km south of Jiroft in southeast Iran) is the main excavation site in the Jiroft Valley. Several high mountain chains surround it, some of them rising to 3700 m asl (Fig. 1). The Halil Rud stretches from north to southeast for almost 400 km through fertile agricultural land before draining into the Jazmurian playa south of Konar Sandal. The water level in the river fluctuates throughout the year.

Results
The sediment core was divided into six major units based on the sedimentological, geochemical, and palynological characteristics (Fig 2 and Fig. 3). The elemental ratios (Si/Al, Ti/Al, and Fe/Al) had relatively low values in Unit 1 (U 1; 250-189 cm; 4011-3548 cal yr BP). The first significant appearance of Cerealia-type pollen occurred in this unit extending from 3880-3700 cal yr BP (230-207 cm). The δ13COM showed a distinct increase in Unit 2 (U 2; 189-164 cm; 3548-3293 cal yr BP). Unit 3 (U 3; 164-134 cm; 3293-2897 cal yr BP) was characterized by high elemental ratios (Si/Al, Ti/Al, and Fe/Al). The K/Ti ratio had the highest values in the entire core in Unit 4 (U 4; 134-106 cm; 2897-2302 cal yr BP). δ13COM values were more negative in Unit 5 (U 5; 106-61 cm; 2302-1540 cal yr BP). Unit 6 (U 6; 61-10 cm; 1540-854 cal yr BP) was characterized by moderate values of different elemental ratios. 


Discussion
Around 3950 cal yr BP a wet period prevailed based on elemental ratios, stable C isotope, and pollen (Fig. 3). Between 3900 and 3300 cal yr BP, mild climate conditions developed. significant appearance of Cerealia-type pollen and agricultural activities existed between 3900 and 3700 cal yr BP. Dry and windy conditions followed from ca. 3300-2900 cal yr BP with the driest conditions around 3200 cal yr BP coinciding with the regional Late Bronze Age cultural collapse. The driest conditions in this dry period occurred around 3200 cal yr BP, coinciding with the decline of the Jiraft Bronze Age civilization at the end of the Bronze Age. The long wet period extending from 2900 to 2300 cal yr BP with a high presence of Sparganium-type and intensive agricultural practices. Wet conditions in the Jiroft valley from about during this period, simultaneously with the flourishing of the powerful Medes and Achaemenid empires, facilitated extensive agriculture. The decline of the Achaemenid Empire coincided with the beginning of a dry period that made agriculture less prosperous in Jiroft Valley for nearly 200 years. The highest Ti/Al values coeval with the lowest δ13COM values suggest an increase in Aeolian activity and dry conditions between 2100 and 1650 cal yr BP. The Jiroft Valley once again experienced humid conditions between 1550 and 1300 cal yr BP, which coincides with the economic prosperity of the mid to late Sassanid Empire (Fig. 4). 

Conclusion
In the present study, using a combination of geochemical and pollinological indicators, we examine the paleo-environmental changes of the ancient Jiroft valley in the southeast of Iran during the past 4000 years and their possible effects on the settlements of the Bronze Age and the main dynasties that ruled Iran based on records. 
The Jiroft Valley experienced wet conditions between 1550 and 1300 cal yr BP, which overlapped with one of the most extensive territorial boundaries in Iran’s imperial history (the Sassanid Empire in the early 7th century C.E.). Although mild conditions prevailed between 1315 and 854 cal yr BP, agricultural activities declined, probably due to weak succession and political instability. We evaluate the archeology and history of territorial borders, economic and political prosperity. Paleo-environmental reconstruction shows that the wet periods and increased agriculture in the Jiroft Valley coincided with the peak of political influence and economic wealth of the Achaemenid and Sassanid empires. Therefore, more detailed paleoclimatic records would be helpful for investigating the interplay of political and climatic factors in the development and decline of ancient settlements and imperial powers in Eurasian history.
