In the world practice, lead-zinc karst deposits occupy one of the leading positions in terms of reserves and rich ore mining. In terms of metal content, they excel all other commercial-genetic types. Karst deposits are a new commercial-genetic type for Kazakhstan. One of the promising regions for discovery of the karst deposits is the Great Karatau, known for such objects (Achisai, Karasai, Kantegi, Araltau and oth.). The area of the Achisai ore cluster is composed of thick carbonate strata of limestones and dolom...

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, ...
