| 摘 要： | 廖家坪金矿床属江南地轴东南缘桃江－城步锑金多金属成矿带的一部分,以NE向桃江－城步深断裂为导矿构造,以长度＞2km,地层断距＞200m的矿区主干断裂为配矿构造,以早期NWW向剪切劈理带中叠加的长度＜1km,地层断距不明显的次级断裂破碎带为容矿构造,矿区38条金矿脉构成两个含矿带8个矿脉群,含矿带的分布与地层岩性有一定关系,矿脉群的分布与早期花岗斑岩脉关系密切,金矿脉主要有4组,NNE向组最发育,NWW向组规模最大,矿化富集与围岩蚀变种类及强度,矿脉交切部位及产状变化段关系密切,根据区域成矿地质条件,金矿床成矿规律,指出湘中地区有廖家坪、白云铺、三德堂矿区及外围和古台山地区4个廖家坪式金矿床找矿远景区。

| Abstract: | Au deposit of Liaojiaping is a part of Sb-Au polymetallic metallogenic zone along with Tiaojiang-Chengpu structural zone on the Eastsouthern fringe of Jiangnan earth aix. The deposit takes the NE trend's Tiaojiang-Chengpu deep-seated fault as the trans-ore soures structure, takes the main fault of length > 2km with strata's fault displacement > 200m, in the mine, as made-up ore structures, takes the early NWW trend's shear cleavage zone being superiomposed with sub-fracture zone of length < 1km with unobvious strata's fault displacement as ore-contained structures. 38 Au ore veins form the two ore-bearing zones and 8 groups of ore veins, in the mine, the distribution of the ore-bearing zone has fixed relationship with lithology of the strata, the ore vein groups have a close relationship with granite porphyry. There are mainly 4 sets of Au ore veins in the mine, and the NNE trend set is the most growth, and the NNW trend set's scale is the largest. The mineralization richening regular in the mine has a close relationship with the types and intensity of wall rock alteration, the intersect places and occurrences chang sections among ore veins. Based on regional metallogenic geological conditions, metallogenic regular of Au deposits in the middle Hunan, the author points out there are 4 "Liaojiaping style" prospect foreground areas of Au deposit in middle Hunan, i.e. Liajiaping area, Beiyunpu area, Sandetang area and its periphery, Gutaishan. |
