广西弄屯铅锌矿地质特征及成因分析

Geological Characteristics and Genesis Analysis of the Nongtun Lead-Zinc Deposit,Guang Xi

弄屯铅锌矿为近年来在广西大明山地区新发现的一处大型铅锌矿床。其基础地质工作研究较为薄弱,控矿因素尚未查明,矿床成因有待进一步探讨,严重制约了该矿床的开发利用。本文通过对弄屯铅锌矿的区域地质背景,矿床地质特征分析,结合成矿流体特征,探讨该矿床的类型和成因。认为弄屯矿区铅锌矿的成因类型为中低温热液充填型矿床,并为今后的找矿工作提供一定的指导和借鉴。

The Nongtun deposit is a large-scale lead-zinc deposit newly discovered in the Damingshan area of Guangxi in recent years.The research on its basic geological work is relatively weak,the ore-controlling factors have not been ascertained,and the genesis of the deposit remains to be further explored,which seriously restricts the development and utilization of the deposit.This paper explores the type and origin of the deposit by analyzing the regional geological background,the geological characteristics of the deposit,and the characteristics of the ore-forming fluid.It is believed that the genetic type of the lead-zinc deposit is a medium-low temperature hydrothermal filling deposit,and provides some guidance and reference for future prospecting work.
