金矿的地质地球化学找矿标志

On gold prospecting indicators by geochemistry

地层和岩浆岩含金高丰度是金矿赋集的物质来源,断裂构造是容矿、储矿的空间。一般说来,金成矿物质越丰富,就越有利于形成大矿、富矿。以江西金矿找矿为例,阐述正确圈定金异常,合理布置探矿工程,获得找金成果新突破的实际意义。

High gold-bearing abundance in strata and magmatic rocks is a material source of gold enrichment. Fault structure can cause a space of ore reservoir. In general, the more abundant the gold mineral-forming materials, the more the large and rich ore deposits form. Taking gold prospecting in Jiangxi as example, an operation idea was put forward including correct determination of gold abnormity and its banded characteristics of concentration on the basis of geochemical data. Through rigid verification of gold abnormity by an exploration from light-duty to heavy-duty process, under the comprehensive study both chemical exploration and geological methods, new gold ores can be detected in a contractible target area.
