江西银峰尖金矿床地质特征及成因

Geological Characteristics and Genesis of Yinfengjian Gold Deposit in Jiangxi

银峰尖金矿位于东乡火山盆地中部,为一处中低温热液充填交代型金矿床。金矿体多呈脉状展布于SN向蚀变破碎带内。燕山期强烈的裂隙式火山喷发为金矿体的形成提供了一定的物质来源和必要的动力,同时为金矿体的迁移、富集提供了良好的迁移通道和赋存空间。通过对其矿床地质特征及成因的浅析,为区域上寻找相似的金矿床提供重要的理论依据。

Yinfengjian gold deposit which is located in the middle of Dongxiang Volcanic Basin is a typical medium-low temperature hydrothermal filling metasomatism gold deposit.Gold ore bodies are mostly vein-like in the SN-trending altered fracture zone.The strong fissures volcanic eruption during Yanshan period has provided resouce and power for the formation of the ore bodies,it also provides the dispersal corridor and reservoir space for the ore bodies.By analyzing the geological characteristics and genesis of its deposits,it provides an important theoretical basis for finding similar gold deposits in the region.
