贵州望谟安乐萤石矿呈脉状、似层状赋存于二叠系上统吴家坪组张性断裂构造和三叠系罗楼组底部"硅化蚀变体"中.本文在总结该区萤石矿床地质特征的基础上,分析了矿床形成时期、空间分布规律、成矿物质来源、界面与构造控矿成矿规律.根据成矿规律分析结果,认为该区萤石矿与地层岩性(界面)、构造、围岩蚀变等地质条件相关,为浅成低温热液矿床,同时总结4个找矿标志,旨在为新一轮找矿突破战略行动萤石矿找矿工作提供参考.
The Anle fluorite deposit in Wangmo,Guizhou Province is in the tensional fault structure of Upper Permian Wujiaping Formation and the"silicified erosion variant"at the bottom of Triassic Luolou Formation.On the basis of summarizing the geological characteristics of the fluorite deposit in this area,the formation period,spatial distribution law,ore-forming material source,interface and tectonic metallogenetic regularity are analyzed.The results show that the fluorite deposit in this area is related to geological conditions such as stratigraphic lithology(interface),structure and alteration of surrounding rock,and is an epithermal deposit.This paper summarizes 4 prospecting signs in order to provide reference for a new round of prospecting breakthrough strategic action for fluorite ore prospecting.
