A great number of space images of the Caspian syneclise taken from various space carriers is currently available for free. The article presents a decryption scheme made using 37 images covering the entire territory of the Caspian Sea. Shooting conditions were selected as cloudless as possible. The season was spring. A mosaic of thermal images has been assembled from individual images with the use of the QGIS program. The decryption schemes analysis was carried out for the period from 1973 to 2021. An expert (authors) decoding was also carried out to identify the geomorphological and landscape features of the most common lineaments. As stated in this paper, lineaments are straightened and (or) linearly organized elements of the image of natural genesis. Numerous circular photoanomalies of various severity and size were also distinguished during visual decoding. Large numbers of local phototone and photo pattern anomalies were highlighted in the images, indicating the position of the salt domes of the Caspian Sea and brachyanticlines spread within the adjacent territories. Comparison of the lineaments deciphered in this work with previously compiled maps showed that almost all objects identified earlier are depicted on satellite images, but previously unknown ones are also highlighted. Particular attention in this work is paid to the identified intersections of lineaments since they are often the indicators of the highest permeability of the lithosphere. Mineral deposits, including hydrocarbons, are most often associated with them. The resulting diagram compiled according to the results of computer and expert decryption shows previously uncharted lineaments.
