银洞沟—许家坡金银多金属成矿带地质地球化学研究

Geological-Geochemical Investigation of the Ylndonggou Xujiapo Au-Ag-multimetal Metallogenle Belt

本文剖析了鄂西北地区银洞沟—许家坡矿化带的地质背景和金银多金属矿床的地质特征,研究了典型矿床的成矿物理化学条件和稳定同位素地球化学特征,探讨了成矿物质及成矿流体的来源,总结了矿化带中金银矿床的成矿模式.

The geological setting of the Yindonggou, Xujiapo mineralization belt in the northwestern area of Hubei province and the geological features of the Au-Ag-multimetallic deposits are analysed. In addition, the metallogenetic physicochemical conditions, stable isotope geochemical characteristics and the sources of ore-forming materials and solutions for some typtical mineral deposits are also discussed. Based upon the discussion we summed up a metallogenic model for the deposits in this district.
