| 摘 要： | 陕西镇安-旬阳地区是南秦岭重要的金属矿产地之一,形成的主要金属矿种有铅锌矿、汞锑矿和金矿.它们在物质来源、成矿物化条件和成矿流体性质等方面既有联系又有差异.通过总结该地区的同位素及流体包裹体资料,结合其他地球化学动力学背景分析认为:铅锌矿和金矿物质来源均与海底喷流作用有关,而金矿和汞锑矿则具有相同的成矿背景.它们构成镇安-旬阳地区晚古生代到早中生代的一个互有联系的成因体系.

| Abstract: | Zhenan-Xunyang area of Shaanxi Province is one of the main metal mineral sources in Southern Qinling Mountains. The major metal resources are Hg-Sb, Pb-Zn and Au deposits, which are different but correlative in source materials, physical-chemical conditions and the characters of mineralizing fluid. By the study on the isotopes and fluid inclusions in the area, with analysis of their geodynamics background, it shows that the source material of Pb-Zn deposits and Au deposits are both related to submarine exhalation, and the mineralization backgrounds of Hg-Sb deposits and Au deposits are the same. The deposits are related to each other, forming a genetic system from Late Paleozoic to Early Mesozoic eras in Zhenan-Xunyang area. |
