| 摘 要： | 青岗坪金矿位于华北地块南缘熊耳山变质核杂岩中部,其矿化类型为构造蚀变岩型。熊耳山变质核杂岩之拆离断层和次级断裂是该区的主要控矿构造,矿体主要赋存在层间破碎带中部的强硅化蚀变岩和蚀变糜棱岩中,金品位平均为7.04×10-6;成矿流体的1δ8OH2O为2.7‰-6.6‰,δDH2O为-63.1‰--96.3‰,成矿流体主要来源于岩浆水;石英包体测温结果为347.5-370℃,矿床成因类型属于中高温热液金矿床。

| Abstract: | Qinggangping gold deposit lies in the Xiongershan metamorphic core complex which is in the south of North China.The mineralization type is structural alterations.The Xiongershan detachment-metamorphic core complex is the main ore-controll structure.Most gold ore-bodies locate within the fractured zone of the fault and the mylonite zone.Au concentration grade is 7.04×10-6.δ18 OH2O value of ore fluid ranges from 2.7‰ to 6.6‰,δDH2O value from-63.1‰ to-96.3‰,indicating that the ore fluid is dominantly magmatic water,with the component of fluid inclusion.The temperature of fluid inclusions ranges from 347.5 to 370 ℃.The deposit genetic type is attributed to meso-epithermal of gold deposit. |
