This article presents the interim results of geoarchaeological research conducted in northwestern Colchis. While the analysis is still ongoing, several significant findings and correlations have been identified. Of particular interest is the finding that the region surrounded by the Kelasur Wall exhibited the highest concentration of iron particles in the clay. The second region with a notably high iron content in the clay was the area of the Great Pitiunt, the primary Roman outpost. The spread of Christianity in the region is hypothesized to have originated from Roman fortifications and spread along trade routes, influencing the distinct religious and cultural identity of the region Bzyb Abkhazia, an area with limited access to the major mountain passes of the Greater Caucasus. Additionally, the geology of Bzyb Abkhazia, characterized by high sedimentary carbonation, contrasts with both the southern and northern regions. Although a direct correlation with historical processes is yet to be fully established, further research into the unique geological and historical features of the micro-regions of northwestern Colchis promises valuable insights for future studies.
