ORIGINALITY SEMIGORSKІY VOLCANO IN NORTHWEST CAUCASUS
The results of study of mineral composition of eruption product of Semigorsky mud volcano. Accessory mineralization of heavy fraction extracted from mud breccias was carried out by electron microscopy. It was found the presence of individuals and aggregates of native minerals, sulfides, oxides, phosphates, lead minerals, carbonates. Study on mineral composition of coarse fraction brought out two forms of mineralization — carbonate and silicate. Characteristic feature of ore process in mud volcano is polymetallic specialization in Cretaceous sediments.
Key words: mud volcano, mud breccias, native elements, physicalchemical conditions.
