云南南秧田钨矿矿床地质特征及成矿控制因素浅析

Geological characteristics and metallogenic controlling factors of nanyangtian Tungsten deposit in Yunnan Province

南秧田钨矿床位于云南省文山州麻栗坡县南南西方向,地质构造单元为华南褶皱系西南角,滇东南拗陷褶皱带老君山锡钨成矿区西南侧。受区内地层、岩性、区域变质作用及热液迭加形成了较典型“层控矽卡岩”型矿床,通过对矿床地质特征的分析,进一步总结该区成矿控制因素,认为具有较好的找矿前景。

Nanyangtian tungsten deposit is located in malipo County,Wenshan Prefecture,Yunnan Province.The geological tectonic units are the southwest corner of South China fold system and the southwest side of Laojunshan Sn-tungsten deposit in the fold belt of southeast Yunnan Depression.Due to strata,lithology,regional metamorphism and hydrothermal superimposition in the area,a relatively typical "strata-controlled skarn"type deposit is formed.Through the analysis of geological characteristics of the deposit,the controlling factors of mineralization are further summarized and it is considered that the deposit has a good prospecting prospect.
