Genetically, gold ore dcposits in Hunan may be divided into 8 majortypes and 16 subtypes. Ore deposits of main types are controlled by differentgeotectonic units. For example, metamorphic-hydrothermal gold ore deposits(Ⅰ) and their associated magmatic-hydrothermal superimposed reformation- type ones (Ⅳ)mainly occur within the Mashan-Lonshan-Ziyunshan EW-trending quaquaversal rise area between the Xuefengian ancient land andthe central Hunan sag.

Genetically, gold ore dcposits in Hunan may be divided into 8 majortypes and 16 subtypes. Ore deposits of main types are controlled by differentgeotectonic units. For example, metamorphic-hydrothermal gold ore deposits(Ⅰ) and their associated magmatic-hydrothermal superimposed reformation- type ones (Ⅳ)mainly occur within the Mashan-Lonshan-Ziyunshan EW-trending quaquaversal rise area between the Xuefengian ancient land andthe central Hunan sag. Their ore-forming epoches are Xuefengian andCaledonian. The latter was superimposed by Yanshanian post-magmatichydrothermal solutions; Magmatic-hydrothermal Au-Pb-Zn polymetallie oredeposits and magmatic-hydrothermal Au-bearing polymetallic ore deposits(associated gold) are located in the Lanyang-Linwu SN-trending foldzone consisting of Late Paleozoic formations. Their ore-forming epoch isYanshanian. In the past, the exploration and mining of gold ore depositswere mainly centred around Precambrian metamorphic-hydrothermal ones.As a result of a prospecting breakthrough of recent years, magmatie-hydrothermal Au-Pb-Zn-Ag polymetallic ore deposits and Quaternary placergold ore deposits, together with metamorphic-hydrothermal gold ore depositshave become the ones of main types in Hunan. Thus, a new prospectingfield has been opened up.

湖南金矿的成因类型可划分为8大类16亚类。主要类型矿床受不同大地构造单元控制。如变质热液金矿(Ⅰ)及与其相关联的岩浆热液叠加改造型金矿(Ⅳ),主要产于雪峰古陆与湘中凹陷的马山—龙山—紫云山东西向穹窿状隆起区内,成矿期为雪峰期与加里东期,后者(Ⅳ)有燕山期岩浆期后的热液叠加;岩浆热液金-铅-锌多金属矿床及岩浆热液含金多金属矿床(伴生金),均产于晚古生代地层的铜山岭—水口山—七宝山北东向深熔构造岩浆带中,成矿期为燕山期。以往金矿的勘查主要集中在前寒武系的变质热液金矿,近几年的找矿突破,已使岩浆热液金-铅-锌-银多金属矿床及第四系砂金矿床,与变质热液金矿床一起,成为该省金矿的主要类型,从而开拓了新的找矿领域。

Yingbishan gold ore deposit is a volcanic hydrothermal deposit hosted in the volcanic breccias chimney whose occurrence is controlled by the nearly-transmeridional fracture F_1 in the ore field.The ore bodies are strictly confined within the fractured zones with different orientations in the pipe, and the nonhomogeneous gold mineralization mainly displayed the relationship between the mineralization and the intense silicatization as well as the fine-micro grained pyritization . From the middle of the pipe towards the marginal rim the ore-tenor exhibits the decreasing tendency implying that the mineralizing material sources have originated from the central parts of the pipe.In the term of the ore-forming process mechanism, the Jurassic period volcanic rocks (K1y)invaded along the hanging wall of the incipient fracture F1(conducting structures) and formed the breccias chimney, and the later stage auric volcanic hydrothermal fluids filled the tensional fractures (host structures)in the pipe finally yielded this volcanic hydrothermal gold ore deposit.

影壁山金矿是一个产于火山角砾岩筒内的火山热液型金矿床,而角砾岩筒又受区内近东西向的断裂F1的控制。矿体产出的位置严格限定在角砾岩筒内多组不同方向的断裂破碎带内,金矿化主要与强硅化、细粒-微细粒黄铁矿蚀变有关,矿化极不均匀,从岩筒中部向岩筒边部品位有降低的趋势。在成矿机制上侏罗纪火山岩(K1y)沿早期断裂F1(导矿构造)上盘上侵形成角砾岩筒,而后期含金火山成矿热液又沿角砾岩筒内部张性断裂(容矿构造)充填而形成金矿床。
