Gold and gold-bearing volcanogenic massive sulphide deposits of the Central Cuba
Известия высших учебных заведений: Геология и разведка, 2021 Background. Volcanogenic massive sulphide deposits (VMS) are the most important sources of Cu and Zn; they account for a large share of the world production of Pb, Ag, Au, Se, Te, Bi and Sb, as well as small amounts of many other metals. The polymetallic
