浙江诸暨璜山金矿构造特征及深部找矿预测
|
摘要
诸暨璜山金矿是浙江省著名的金矿之一,位于江山-绍兴断裂带北东段。本文通过对璜山金矿和庙下畈金矿的构造特征进行对比研究,认为这两个金矿形成的构造背景和成矿时代基本相同,但矿体走向和剪切动向截然不同,璜山金矿赋存于NE走向的剪切带内,庙下畈金矿位于NW走向的剪切带内,二者构成共轭剪切带,叠加在江山-绍兴主干韧性剪切带之上。成矿后该区先后受到NW-SE和NNE-SSW方向的挤压,形成NW走向和近SN方向的脆性断裂,对矿体起到破坏作用。依据共轭剪切带的空间分布,推测江绍断裂南东侧可能存在与璜山金矿对应的赋矿剪切带,该带位于新元古代陈蔡群变质岩之下,埋藏较深,是璜山地区深部找矿的有利勘探区。
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 JiangshanShaoxin 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.
