摘要
贞丰水银洞金矿床是通过成矿预测发现的以层控型为主、断裂型为辅的复合型隐伏卡林型金矿床。是滇黔桂"金三角"金矿勘查区层控卡林型金矿的典型代表。在概括水银洞金矿床地质特征的基础上,对矿区内典型金矿点构造蚀变体作了初步的研究与分析,并结合前人研究资料,从成矿物质来源、成矿阶段2个方面对矿床成矿规律进行探讨,初步认为水银洞金矿床的成矿物质来源主要为深部的隐伏岩体;矿床可划分为沉积成岩期和构造-热液期2个成矿期。
The Shuiyindong gold deposit in Guizhou province was found by metallogenic forecas- ting in the middle 1990＂s, and it has been found to be a complex concealed deposit which com- position with stratabound-based, supplemented by fracture-type. The gold deposit is the first I exploration type Carlin-type gold deposits in China . It is a typical representative stratabound Carlin-type deposit for mineralization forecasting in ＂ Gold Triangle＂ of Yunan, Guizhou and Guangxi. But now there is no systematic studying on the metallogenic regulari- ty of this kind deposits. On the basis of summarizing the geological features of the Shuiyin- dong gold deposit, the auther have made the preliminary analyising on tectonic altered vari- ant of typical gold occurrence of this gold deposit. Combining with previous studies on the basis of information, discussing the metallogenic regularity from the metallogenic matter ori- gin, metallogenie state and Summarized the deposit metallogenic regularity. Preliminary view about the metallogenetic matters of the Shuiyindong gold deposit came from the deep hidden igneous rocks, The deposit is divided into two mineralization stages, namely sedimen- tary diagenetic stage and tectonic-hydrothermal stage, which has the important reality in- structional significance of further impelling the prospecting for the similar Carlin-type gold deposits and the deep part and periphery of the Shuiyindong gold deposit.
