Source of Ore-Forming Materials and Mineralization of the Saidu Gold Deposit, Southern Altai, China

Abstract:

Saidu gold deposit, located in back arc basin at south margin of the west Altay Mountain, is orogenic gold deposit. It is strictively controlled by ductile-shear zone, occurring in altered mylonite zone of Mar-kakol giant belt. The δ³⁴S values of pyrite in the gold deposit range from 3.53‰ to 5.88‰; the lead isotopic compositions are fairly constant, with ²⁰⁶Pb/²⁰⁴Pb ranging from 18.010 to 18.359, ²⁰⁷Pb/²⁰⁴Pb ranging from 15.488 to 15.579, and ²⁰⁸Pb/²⁰⁴Pb ranging from 38.1116 to 38.3551. Sulfur and lead isotope studies indicated that ore-forming materials originated from the deep portion, and had close relationship with magmatic activity. The ore materials were obtained from rocks of the lower crust during the orogenic period; the main gold mineralization should have relations with tectonic extention settings of post-collision orogenic.
