湖南省隆回县杏枫山金矿床地质特征及成矿模式探讨

杏枫山金矿床位于湘中白马山一龙山东西向构造带与古台山一新宁南北向构造带的交汇部位，是一典型的石英细脉带型金矿床。在研究矿区地质特征基础上，通过对矿体特征、矿石成分、成矿作用过程等分析研究，提出该矿床成矿模式。认为该矿床的形成主要经历了4个阶段：第一阶段，青白口系高涧群初始矿源层的形成；第二阶段，区域深大断裂，变质作用阶段，金元素聚集、分解、化合、氧化、还原、沉淀、再循环，形成矿化富集层；第三阶段，多次岩浆活动，成矿热液形成，断裂构造活动，形成运移通道；第四阶段，岩浆活动，旧断裂复活，新断裂产生，金富集成矿。

Geological characteristics and metallogenic model of Xingfengshan gold deposit in Longhui County,Hunan Province

Xingfengshan gold deposit in Hunan Province Longhui County, which is located in Baimashan-Longs- ban east-west tectonic belt and Gutaishan-Xinning south-north tectonic belt junction place,is a typical quartz fine vein belt type gold deposit. Based on the study of geological characteristics, through the features of ore bodies, mineral com- ponents,mineralization process analysis and research,etc,this paper puts forward the deposit metallogenic model. The ore formation mainly experienced four stages： the first stage, the primary source bed formation in Qingbaikouan Peri- od, the second stage, regional deep tectonic, metamorphism phase, gold element gathered, decomposition, combining, oxidation, reduction, precipitation, recycle, form mineralization enrichment layer, the third stage, multi-phase magmatic activity, metallogenic hydrothermal formation, fracture tectonic activities, form migration channel, the fourth stage, mag- matic activity, old fracture resurrection, new fracture generate, gold enrichment.
