摘要
湖南安化泉塘金银矿点处于安化-浏阳构造带与桃江-城步构造带的复合部位,沩山岩体、芙蓉岩体的北西侧。根据矿体的地质背景、化探异常、形态规模等特征,分析了其成矿机制及成矿模式。认为区内金银锑钨成矿与脆-韧性构造及花岗斑岩脉关系密切,在化探异常显著且成矿有利的构造部位可能存在较大规模的隐伏矿体,具有较好的找矿远景。
Quantang gold-silver ore spot in Anhua,is located in the compound part of Anhua-Liuyang structural belt and Taojiang-Chengbu structural belt,and the north west side of Weishan and Furong rock mass.According to the characteristics of the geological background,geochemical anomaly,morphological scale of the ore body,the metallogenic mechanism and model are analyzed.It is considered that the mineralization of Au-Ag-Sb-W is closely related to brittle-ductile structure and granite porphyry vein in the area.There may be a large concealed ore body in the structural position with significant geochemical anomalies and favorable mineralization,which has a good prospecting prospect.
