金盆沟地区金成矿地质特征及其找矿前景分析

金盆沟地区位于石泉-旬阳金成矿带,志留系下统梅子垭组广泛分布,以富含炭硅质为特征,素有"黑色岩系"之称,为区内主要含金岩系和赋矿层位。从地层条件、热源条件、构造条件、围岩蚀变等方面简述金盆沟地区金成矿地质背景,对金成矿地质条件、成矿规律进行了总结、分析,并与黄龙金矿床成矿特征类比,认为二者在成矿地质环境、含矿层位、矿体特征、围岩蚀变、矿床成因等方面基本相同,同属热液改造型金矿床,且具有有利的金成矿地质条件和良好的找矿前景。

Jinpengou geologic characteristics of gold mineralization and its prospective analysis

Jinpengou area is located in the Shiquan-Xunyang gold metallogenic belt, Meiziya group the Silurian department widely distributed, rich in carbon, siliceous is characterized by, known as the ＂black rock series＂, as a major regional gold-bearing rocks and ore-bearing strata. The geological back- ground of gold mineralization is elaborated from the formation conditions, heat conditions, structural conditions and wall rock alteration. The geological conditions of the gold mineralization and the mineral- ization law are analyzed,which is compared with characteristics of Huanglong gold mineralization, showing that two are basically same in the ore-forming geological environment, ore-bearing strata, ore body characteristics, wall rock alteration, and ore genesis, belonging to the hydrothermal-modified gold deposit, with good geologic conditions of gold mineralization and good ore prospects.
