河南省石窑沟金矿地质特征及成因探讨

河南省石窑沟金矿是近年来在熊耳山—外方山金成矿带上发现的一个中型金矿。从区域地质背景、矿区地质、矿床地质特征、矿床成因等方面对该矿床进行较为全面的研究,指出马超营大断裂的多期活动和多次热液作用特别是燕山期强烈的火山热液活动是成矿的主要因素,矿体严格受马超营大断裂的控制,矿床成因类型属中低温热液构造蚀变岩型,总结找矿标志,指出找矿方向,并提出建议。

Geological characteristics and genesis of Shiyaogou gold deposit in Henan province

The Shiyaogou Gold Deposit in Henan Province is a medium-sized gold deposit,which was discovered in the Xiongershan-Waifangshan metallogenic belt in recent years.The regional geological background,mine geology,geological characteristics of ore deposit and ore genesis are studied in this paper.It is indicated that the main factors in mineralization are multi-period activities of Machaoying major fracture and multiple hydrothermal process especially the volcanic hydrothermal activity.The ore body is strictly controlled by Machaoying major fracture,and the ore genesis type is middle-low temperature hydrothermal structural altered rock type.The prospecting criteria and direction are analyzed,and recommendation is made for the future work.
