Abstract
As inferred from melt inclusions in minerals of volcanogenic rocks, the ore-magmatic pyrite systems of Rudny Altai and Tuva had quite a specific history. Volcanism manifestations in these regions have both similarities and differences.
The chemical composition of melt inclusions in quartz of acid volcanic rocks from the pyrite deposits of Rudny Altai is close to the chemical composition of the rocks, and in REE content they correspond to island-arc magmas. At early stages of development of a magmatic system, acid melts formed, which had high temperature (1230-1250
