This study investigates and evaluates emergency conservation methods at the Chogha Zanbil archaeological site, focusing on the conservation of excavated features including shafts, shallow grids, and architectural remains. The primary objective of these interventions was to Conservation of Excavated Remains against environmental factors such as moisture, erosion, and gradual decay, either temporarily or over extended periods. The research methodology involved field observations, assessment of available materials, and reference to previous conservation practices at the site. The use of crushed gravel and sand with a variable grain size between 2 and 20 millimeters was recommended for backfilling trenches and shafts. Care was taken to avoid impurities such as gypsum, anhydrite, and various sulfates, which could contribute to the formation of soluble salts and damage the archaeological features. The protective coverage of shafts, networks, and the exposed brick platform was implemented in a phased manner, based on their depth and archaeological significance. For deeper shafts, stratified layers of gravel and soft soil with appropriate compaction were employed, while shallow grids were covered with a thin layer of gravel followed by backfilling with excavated soil. Special attention was given to the conservation of the inscribed brick platform, which was protected using a base layer of fine sand. The findings indicate that the use of natural materials combined with scientifically informed and experience-based approaches can be effective in the temporary or long-term conservation of excavated features in archaeological sites.
