| 摘 要： | 金窝子金矿构造上地处星星峡古生代岛弧南缘，红柳河断裂以南，包括南、北两矿区（ 金窝子金矿和２１０ 金矿） 。根据金矿化与岩体的空间关系，分产在花岗岩体中的金矿和围岩中的金矿两种类型。按矿化类型又可分为含金石英脉型和蚀变破碎带型。矿床在空间上和成因上与金窝子花岗岩关系密切。矿床地球化学研究表明，硫为深源硫，来自深部岩浆。包体以液相包体为主，其次有少量气态包体，还有ＣＯ２ 多相包体。包体成分类型属于ＣＯ２ － Ｈ２Ｏ－ ＮａＣｌ 型。热液水以岩浆水为主，矿床形成于碱性还原条件，为一典型的岩浆热液型金矿。

| Abstract: | The Jinwozi gold deposit is located to the south of Hongliuhe fault on the southern margin of the Xingxingxia isoland arc. It comprises ores hosted in granite and those in sedimentary clastic rocks of Lower Permian. Orebodies occur as gold-quartz veins and gold-bearing altered rocks. It is spatially and originally related to the granite. The sulfur of ores derived from deep magmatism. The fluid inclusions are dominated by liquid inclusions, and secondly gaseous inclusions and CO 2 inclusions. The inclusion composition features CO 2-H 2O-NaCl. It was formed under alkaline and reduction condition with domination of magmatism-derived water. It is originally of one typical magmatic hydrothermal gold deposit. |
