甘肃小柳沟钨钼矿床地质特征及成因分析

Analysis of the geological characteristics and causes of tungsten tantalum deposits in Xiaoliugou, Gansu

为分析小柳沟钨钼矿床地质特征、矿床成因以及为区域找矿勘查工作提供理论支撑,本文总结了矿床地质特征,分析了成矿规律和矿床成因。研究表明,小柳沟钨钼矿床的矿石类型较复杂,但成矿过程为岩浆侵入演化的连续过程,成因属于火山喷流沉积改造型矿床;在背斜核部、接触带的层间滑脱带部位是今后主要的找矿勘查方向。

To analyze the geological characteristics of tungsten tantalum deposits in Xiaoliugou,the causes of mineral deposits and to provide theoretical support for the exploration of mineral deposits,this paper summarizes the geological characteristics of mineral deposits,and analyzes the law of mineralization and the causes of deposits.The research shows that the ore type of the tungsten tantalum deposit in Xiaoliugou is more complex,but the mineralization process is the continuous process of magma intrusion and evolution,the cause belongs to the volcanic jet sedimentation transformation ore deposit,and the layer slip zone part of the back slope core and contact belt is the main prospecting direction in the future.
