| 摘 要： | 贵州八客金矿区以产出富金包为特色，找矿及经济意义较大。以探采实践中所获地质资料为基础，通过对成矿地质背景、矿床地质特征与地球化学、物理化学因素的分析，认为含Au石英脉中富金钨的形成除与特定的地质背景有关外，与控制富金产出的小尺度构造部位、地球化学、地球物理条件的有机配置极为密切。富金包存在的标志是：1）石英脉与节理密集带复合部位、盲裂隙带、小尺度褶皱轴部；2）具有复杂硫化物组合；3）围岩蚀变化出现碳化；4）大量CO2包裹体的出现。八客金矿区乃至黔东地区找到富金包的可能性仍然较大。

| Abstract: | The Jinping Bake gold mining area of Guizhou is characterized by the occurrence of the rich gold package,and has great meaning on prospecting and economy.Based on the information of the detecting and mining practice,by analyzing of the ore forming geological setting, geological features of deposits and geochemical,geophysical factors,shows that apart form the certain geological setting,controlling part of the small scale tectonic,geochemical,geophysical conditions are all closely related to the forming of the rich gold package in aurifous quartz veins.The sign of existence of the rich gold package are as follows:1) The compound zone of Quartz vein and close jointed area, blind fissure zone,small scale fold axial zone;2)existing of the complex sulfide assemblage; 3) carbonization occurred in wall rock alteration;4) emerging of a large number of the CO 2 inclusions.Above all,there is still great possibility for finding rich gold package in the Bake gold mining are or eastern Guizhou. |
