SEM micrographs of the stone samples from the Anahita Temple including section and surface of stone samples. a The SE micrograph of the sample K2 that shows the compact structure and the intact texture of the stone; b the BSE micrograph of the sample K1 that indicate evidence of detached stone particles; the replacement of a phase is occurred in a cavity of the matrix texture; c the SE micrograph of the sample K8, in which a deterioration in the form of detachment of the stone’s texture is visible. d the SE micrograph of sample K5 which represents the detachment of the layer; e grain detachment at stone surface in sample K8 in the form of BSE micrograph; f the BSE micrograph of sample K1 which shows the deterioration of stone as a grain detachment; g the image shows evidence of dissolution at the stone surface in sample K6 in the form of SEM micrograph; h the BSE micrograph of sample K10, the lichens hyphae in the stone texture; i the BSE micrograph of the area specified in yellow from sample K10, In the image, the lichens hyphae and degradation in the stone are visible. Results of EDS analyses are presented in Table 4
