吉林省西林河王麻子沟金矿床地质特征及成因探讨

Geological Characteristics and Genesis of Wangmazigou Gold Deposit in Xilin River, Jilin Province

吉林省抚松县西林河王麻子沟地区,呈现金矿床地质。本文对该地区的构造,地层,岩石等控矿因素进行了研究,同时也对金矿体的主要特征,矿石的矿物成分构造和类型等进行了深入的研究。在结合以往勘察成果的基础上,经过矿体铅同位素的测定,我们可以推断出该地区的成矿作用发生在前寒武纪吕梁运动末期。通过硫同位测试,可以推断出该地的矿场属于变质-热液蚀变岩型金矿床。

The Wangmazigou area of Xilin River in Fusong County,Jilin Province,presents the geology of gold deposits.In this paper,the structure,strata,rocks and other ore-controlling factors in this area are studied.At the same time,the main characteristics of gold orebody,mineral composition,structure and type of ore are also studied in depth.On the basis of previous exploration results and the determination of lead isotopes in ore bodies,we can infer that the metallogenesis in this area occurred at the end of the Precambrian Luliang Movement.Through sulfur isotope test,it can be inferred that the ore field in this area belongs to metamorphic-hydrothermal altered rock type gold deposit.
