广东圆顶山金矿地质特征及前景

The Geological Characteristic and the Prospect of Yuandingshan Golden Deposit ,in Guangdong Province

圆顶山金矿属于桂东—粤西金矿带的一部分,区内寒武系浅变质岩系地层,其金含量较高,认为是金矿成矿的初始矿源层。矿区内EW向及NW向构造发育,所发现的主矿体均受控于NW向断裂,呈脉状或复脉状产于构造破碎带中,属破碎带变质热液含金石英脉型金矿。在综合研究矿区地质特征的基础上总结矿床成矿规律,指出找矿标志及目标。

Yuandingshan golden deposit is a part of eastern Guangxi and western Guangdong gold belt. In region gold is rich in Cambrain system lower metamorphic rock series stratum which is regarded as original source bed. EW and NW structures develop in mining area. Main orebodies are controlled by NW faults that exist in the form of vein or compound vein in structural fracture zone, therefore this golden deposit is of metamorphic hydrothermal quartz vein golden deposit in fracture zone. On the base of synthetic research of geological characteristic, ore-forming rule is generalized, indicating prospecting marks and target.
