IRON SULFIDES AS AN INDICATOR OF MINERAL FORMING CONDITIONS IN THE MUD VOLCANOES OF AZERBAIJAN

Iron sulfides are very common in the mud volcanoes of Azerbaijan, genetically diverse and are represented with pyrite, pyrrhotite and marcasite. Iron sulfide crystals originate and grow in the comparative breccia under cavities filled with gas-aqueous carbon fluids containing H2S. Crystals of pyrite are characterized by the presence of complex sculptural complications on the faces of the growth steps.

Growth stages, forming antisceletal forms, complex cluster faces of crystals are formed at moments of abrupt change in the conditions of crystallization. Dashing on the faces appears in conditions of contamination of mineral-forming solutions by mechanical impurities. Mn, Cu and a number of chalcophylic elements occur in mud-volcanic pyrites.

Keywords: sulfides of iron, mud volcanoes of Azerbaijan, conditions of crystallization.
