云南毛坪铅锌矿区外围(龙街地区)综合信息成矿预测

Metallogenic prognosis based on comprehensive information in the outskirts of Maoping Pb-Zn mining area(Longjie area)in Yunnan

文章对毛坪铅锌矿床成因及控矿因素进行了剖析,在前人工作的基础上,提出了沉积-低温热液改造-构造控制成因,归纳出地层、岩性、构造等控矿因素;并对毛坪矿区外围的龙街地区的有利成矿多元地学信息进行了提取,厘定出综合信息找矿模型。最后以GIS为工具,对积累的地、物、化多源信息进行了空间分析和叠加,开展了龙街地区的综合信息成矿预测,圈定7个找矿靶区。

This paper analyzed the genesis and ore-controlling factors of Maoping Pb-Zn deposit,and based on the works of predecessor it presented the sediment-low temperature hypothermal reformed-tectonic con-trolled genesis,and summarized the ore-controlling factors such as strata,lithology and structure.Multifac-tor geoscience information about favorable mineralizationin Longjie area on the outskirts of Maoping mining area was extracted and thus a model of prospecting based on comprehensive information was established.Fi-nally,this paper conducted spatial analysis on and superimposed the geological and geophysical and geochem-ical information on the GIS platform and made the metallogenic prognosis based on comprehensive informa-tion in the Longjie area,and it delineated seven prospecting targets.
