| 摘 要： | 研究了贵州天柱磨山—油麻坳金矿化带的成矿条件、控矿规律及地球化学特征。认为：金元素来源于地层；成矿流体具变质水和大气降水混合特征；褶皱翼部与断裂交汇带及层间破碎带等控制着矿体产出。成矿作用过程具沉积变质改造作用特点，多期次的构造变质作用对金元素的迁移聚集有着重要控制作用。

| Abstract: | The gold-bearing quartz vein of the Mosmaa-Youmaao mineralized zone in Tianzhu Guizhou province occurs in the Qingshuijiang formation of the Xiajiang group volcanic tuffaceous slate. Orefluids were mainly derived from mixing flow of the meteoric water and metamorphic water.Metalloginic environment was the weak reduction type.It is obvious that the initial stage,the tectonics movement and hydrothermal reformation took place the gold element in rich in strata,in the late stage,the gold-bearing quartz veins have been reached through repeated concentration of such metallogenic element as gold under the action of multiple geologic and fluid reforming processes. |
