摘要
河南省光山县上范洼金矿位于豫南重要的银、金成矿远景区,成矿地质背景优越。从研究区地质背景入手,结合地球物理和地球化学方法,上范洼金矿金矿共圈定了3条金矿化体,在分析矿体特征的基础上,认为矿床赋存于中元古界龟山岩组下部白云斜长片岩内,多期构造对成矿有一定的作用,对后续在该区域找矿有一定的参考价值。
Shangfanwa Gold Deposit in Guangshan County is located in the important silver and Sung Kim ore prospect area in the south of Henan province.On the basis of the analysis of the characteristics of the ore bodies,it is considered that the deposits occur in the dolomitic plagioclase schist in the lower part of the Middle Proterozoic Guishan formation.It is also suggested that the multi-stage structures play a certain role in the mineralization,as has certain reference function to follow-up prospecting in this area.
