河南卢氏南阳山锑矿地质特征与成因探讨

Geological characteristics and genesis of nanyangshan antimony deposit in Lushi,Henan Province

为解决近些年许多中小型矿床濒临枯竭的现状,以期寻找到其他地区的同类型矿床,对河南卢氏南阳山锑矿地质特征和成因进行探讨。通过对河南省卢氏县南阳山锑矿矿区内部的地层特征、构造特征、岩浆活动特征等的研究,结合矿床的矿体特征和矿石特征,以及矿区地质特征和矿床地质特征,分析该地区的矿床成因,探究成矿物质来源和构造控矿因素。本区锑矿体受构造控制,多期次的岩浆活动为区内矿产的形成提供了丰富的物质来源基础,岩浆热液是携带锑矿来到地表的主要成矿物质。

In order to solve the problem that many small and medium-sized deposits are on the verge of depletion in recent years,and to find similar deposits in other areas,the geological characteristics and genesis of nanyangshan antimony deposit in Lushi County,Henan Province are discussed.Based on the study of strata characteristics,structural characteristics and magmatic activity characteristics of nanyangshan antimony mine in Lushi County,Henan Province,combined with the characteristics of ore body and ore,as well as the geological characteristics of mining area and ore deposit,the genesis of the deposit is analyzed,and the source of ore-forming materials and structural ore controlling factors are explored.The antimony ore bodies in this area are controlled by structures.The multi-stage magmatic activities provide abundant material sources for the formation of minerals in the area.Magmatic hydrothermal fluid is the main ore-forming material that carries antimony ore to the surface.
