摘要
安徽省五河地区有钱台子、西坂、硖石三个小型金矿在开采,多处金矿点正在勘查。区内成矿地质件较好。太古界五河岩群西崮堆组是金矿有利的成矿围岩和矿源层。郯庐断裂带及其次级构造控制金矿体分布,燕山期岩浆热液流体沿断裂系统充填为大量的岩脉和含金石英脉,形成中—低温热液型金矿床。
There are 3 small gold producing mines as Qiantaizi, Xifan and Xiashi, and many gold prospects under exploration in the Wuhe area, which is good in ore-forming geological conditions. The Xigudui Formation of Achaean Wuhe Group-Complex is the favorable gold ore-forming wall rock and mineral source. The Tan-Lu Fault and its secondary structures control distribution of the gold ore body, and the Yanshanian magmatic thermal fluid moved along the fault to form by filling a great number of dykes and auriferous quartz veins, giving rise to medium-low-temperature gold ore deposits.
