Abstract

Abstract

The Early Carboniferous volcanic apparatus is an important metallogenetic structure for formation of gold deposit in the Western Tianshan.A study on the formation time of the volcanic apparatus, rock types, volcanic facies, eruptive cycles and metallogenetic conditions shows that the volcanic apparatus was formed about 331Ma ago, associated with calc-alkaline series rocks, and bearing volcanic cycle from explosive facies to extrusive facies and then to explosive facies.The volcanic rock has a higher background values of Sb, Pb, Mo, Bi, Au, So, constituting a good conditions for formation of the volcanogenic massive sulfide deposit.
