构造对河南南召县观音庙萤石矿的控制作用

观音庙萤石矿是近年南召县新发现的一处热液充填型脉状矿床,为总结矿床成因、控矿因素,指导下一步勘查找矿,本文在研究该区萤石矿地质特征的基础上,通过分析对比构造作用与成矿之间的联系,提出断裂构造控制了萤石矿的产出,为含矿热液提供了运移通道和容矿空间;构造转折或交叉部位,更易形成厚度大、品位高的萤石矿。

Tectonic control of Guanyinmiao fluorite deposit, Nanzhao County, Henan Province

Guanyinmiao fluorite deposit is a new hydrothermal filling vein deposit discovered in Nanzhao County in recent years. In order to summarize the genesis and ore controlling factors of the deposit and guide the next exploration and prospecting, this paper, based on the study of the geological characteristics of fluorite deposits in this area, through the analysis and comparison of the relationship between structural action and mineralization, draws the conclusion that the fault structure controls the production of fluorite deposits and provides the migration channel and ore holding space for ore-bearing hydrothermal fluids; the structural turning or intersecting parts are more likely to form thick High grade fluorite ore.
