Structural Characteristics and Prediction for Deep Gold Ore Prospecting in the Huangshan Gold Deposit, Zhuji, Zhejiang Province
摘要
Abstract
The Huangshan glod deposit is one of the famous gold deposits in Zhuji,Zhejiang Province.It is located in the northeastern section of the Jiangshan-Shaoxing fault zone.A comparative study on the structural characteristics of this deposit and the Miaoxiafan gold deposit suggests that they have the same tectonic setting,roughly identical mineralization ages,but different ore-body strikes and shear directions.The Huangshan gold deposit occurs in a shear zone of NE-trending,while the Miaoxiafan gold deposit lies at a NW-trending shear zone.The two shear zones constitute a conjugate shear zone superimposed on the main Jianshan-Shaoxing ductile shear zone.The NE-trending and nearly NS-trending brittle fractures,caused by NW -SE and NNE-SSW directed compressive stress after the mineralization,destroyed the early orebodies.According to the spatial distribution of conjugate shear zones,we infer that there is a mineral-bearing shear zone corresponding to the Huangshan shear zone on the south-east side of the Jiangshan-Shaoxin fault.This zone is located under the metamorphic rocks of the Neoproterozoic Chencai group and buried deeply,which should be a favorable exploration block in this area.关键词
