Thin section petrography micrographs of stones samples from the Anahita Temple. a The micrograph of the sample K3, showing the matrix of micrite with a compact texture and low porosity; b the micrograph of the sample K4, which shows secondary calcite formed within the compact calcite matrix, clay veins, and the presence of cleavage and micro-crack in the stone structure; c the micrograph of the sample K3 in dark field (XPL); the image shows multi-texture structure of stone in form of “fine-grained texture (micritic)” and “coarse-grained texture (sparite)” and placement of clay veins between two textures; d the micrograph of the sample K4 indicating the dolomite phase in the stone texture using Alizarin Red S test
