河南信阳西坡萤石矿的矿床成因及成矿过程浅析

Analysis on the Genesis and Metallogenic Process of the Fluorite Deposit in Xipo,Xinyang,Henan Province

河南信阳西坡萤石矿位于豫南萤石矿矿集区内,矿床成因为中低温热液充填型萤石矿床。通过对西坡萤石矿成矿地质背景、萤石矿地质特征等方面的介绍,根据萤石矿结构构造特征和矿脉的穿插关系,将西坡萤石矿的成矿过程大致划分为四个阶段:硅化弱萤石矿化阶段、主成矿阶段、破碎再造阶段和后期(网)脉状萤石矿形成阶段。

The Xipo fluorite deposit in Xinyang,Henan is located in the fluorite ore concentration area of southern Henan.The deposit is a medium to low temperature hydrothermal filling fluorite deposit.Based on the introduction of the metallogenic geological background and geological characteristics of Xipo fluorite deposit,the metallogenic process of Xipo fluorite deposit can be roughly divided into four stages:silicified weak fluorite mineralization stage,main mineralization stage,crushing and reconstruction stage and late(mesh)vein fluorite formation stage according to the structural characteristics of the fluorite deposit and the interspersing relationship of the veins.
