江西包公尖——仙山岗金成矿带地质特征及找矿前景

Geological characteristics and prospecting potential of the Bao Gong Shan Xian Shan Gang gold metallogenic belt, Jiangxi

江西包公尖～仙山岗金成矿带位于华南加里东褶皱系北缘,与钱塘台拗嵌合地带,就位于信江铜银金成矿带东部的铅山～广丰中生代火山岩盆地内。近年在该成矿带内发现两个小型金矿床,即包公尖金矿和仙山岗金矿,分别为构造破碎带型和隐爆角砾岩型,具有典型特征。该成矿带呈北东走向,带长30Km,带宽3Km,次级断裂构造和密集裂隙带发育,蚀变强烈种类多样,化探异常发育,有较大的金矿找矿前景。

The Baogongjian-Xianshangang gold metallogenic belt in Jiangxi Province is located in the northern margin of Caledonian fold system in South China and the Qiantang depression, which is located in the Yinshan-Guangfeng Mesozoic volcanic basin in the east of Xinjiang copper-silver-gold metallogenic belt. In recent years, two small gold deposits, namely Baogongjian gold deposit and Xianshangang gold deposit, have been discovered in this metallogenic belt. They are tectonic fracture zone type and cryptoexplosive breccia type, with typical characteristics. The metallogenic belt is NE-trending,with a length of 30 km and a bandwidth of 3 km. The secondary faults and dense fracture zones are well developed, and the alterations are intense and varied, and the geochemical anomalies are well developed. It has great prospects for gold prospecting.
