夜长坪钼钨矿床成矿控制条件及找矿远景分析

Control Conditions of Formation of Molybdenum and Tungsten Deposits and Prospect Analysis in Yechangping Terrace

本文通过对夜长坪钼钨矿区矿床地质、地球物理特征和成矿控制条件的分析研究,认为该钼钨矿床受矿源层官道口群龙家园组、多组断裂构造交汇部位及燕山期中酸性隐伏小岩体控制,属斑岩-矽卡岩型矿床。并对矿区内及其南部十八盘—大角寺一带具良好找矿远景的地区进行了分析。

Through research on control conditions of mineral formation as well as deposit geology and geophysical features of the area containing molybdenum and tungsten deposits,it is believed that the deposits are attributed to porphyry-skarn strata, controlled by neutral-acid bedrock concealed in ore ledge characteristic of groups of interacting fractures in Guandaukou Qunlongjiayuan dating back to Yanshan era. Investigation has indicated that there is a good prospecting of minerals around the surrounding areas from the mine inside to Shibapan bend-Dajiao temple.
