吉林省磐石市兴隆沟金矿地质特征及成因分析

The geological features and genesis analysis of Xinglonggou gold deposit in Panshi City, Jilin Province

兴隆沟金矿赋存于燕山期花岗闪长岩中,有石英脉型和蚀变岩型两种工业类型金矿。具有厚度和品位变化大、金的粒度从微粒到巨粒、矿石结构与构造多样等特点。本文对磐石市兴隆沟金矿的矿床地质特征进行了分析,论述了矿体特征及矿石质量特征,分析了矿床成因,希望对该区的地质找矿工作有所帮助。

Xinglonggou gold deposit occurs in the Yanshanian Granodiorite , ore is divided into two industrial types,that is , the gold ore of quartz veins and the gold ore of altered rocks. There are larger variations in the thickness of ore body and the grades of ore rock, the grain of the gold changes from the micrograined to the giantgrained, and the ore fabric has the various characteristics. The geological features of Xinglonggou gold deposit is analyzed, the characteristics of ore bodies and ore qualities are discussed, and its genesis is analyzed also. The authors hope that the paper could help for the geological worker in the area working.
