甘肃省西和县三洋坝金矿床成矿规律

A Discussion on Geological Characteristics and Genesis of Sanyangba Gold Deposit,Xihe County,Gansu Province

本文从地层控矿,矿体与岩体的关系,矿体产出及富集规律,成矿模式等方面对三洋坝金矿床的成矿规律加以总结,其中重点是成矿模式,对于在该地区寻找类似矿床提供了基础依据,也为在秦岭西段寻找微细浸染型金矿床提供了探索依据。

In this thesis,a summary on the mineralization regularity of the Sanyangba gold deposit is made on the basis of strata-bound deposit,relation between ore-bodies and magmatic bodies,ore occurrence and enrichment,mineralization formas etc.The mineralization forms are the emphasis.It provides preliminary basis for searching similar ore deposits in this area,and it is also a good probe for searching micro-fine grained disseminated gold deposits in the western part of Qinling Mountains.
