福建尤溪赤墓地区矿产地质结构及成因过程分析

Geological structure and genetic process of mineral resources in Chimu area,Youxi,Fujian Province

福建尤溪赤墓矿区位于闽西北隆起带,闽西南拗陷带和闽东火山断拗带的交汇部位,处于政和—大埔深大断裂带上。区内矿体呈似层状赋存于F1断裂带中,矿体与围岩接触关系一般较明显,部分呈渐变接触关系。本文通过对赤墓地区矿产地质特征的总结、分析,初步认为本矿床的成因为以热液充填为主的热液交代-充填型矿床所形成。

The Chimu mining area in Youxi,Fujian Province,is located at the intersection of the northwest Fujian uplift belt,the southwest Fujian depression belt and the East Fujian volcanic fault depression belt,and on the Zhenghe Dapu deep fault belt.The orebodies in the area are bedded in F1 fault zone,and the contact relationship between orebodies and surrounding rocks is generally obvious,and some of them are gradual contact relationship.Based on the summary and analysis of the geological characteristics of the mineral resources in the Chimu area,this paper preliminarily considers that the genesis of the deposit is formed by the hydrothermal metasomatic filling type deposit dominated by hydrothermal filling.
