The article examines the relationship between the tasks facing geologists and the General state of the economy of the USSR and modern Russia. Since the end of the 19th century, geology has moved away from purely historical research of the Earth and is increasingly focused on the search and exploration of minerals and on merging with the mining industry. Given that the territory of the USSR and modern Russia has almost all types of minerals, it is most profitable to use the resources located on its own territory. H...

The paper considers the structural and tectonic position of the mineralisation in the case of the Achisai ore district. Formation of lead and zinc ores at the Achisai deposit was conditioned by regeneration of stratified ore clusters as a result of tectonic or tectonic-magmatic activation. Therefore, the structural-tectonic control of mineralisation of the Achisai type is one of the cardinal ones, along with the lithologic-stratigraphic one. The lead and zinc mineralisation is confined to side parts of synclines, ...
