| 摘 要： | 塔斯特金矿床为一破碎带蚀变岩型金矿。通过稳定同位素、包裹体、成矿元素及成矿物理化学条件的研究,提出该矿的成矿溶液是岩浆水和大气降水之混合物。成矿元素主要来自深源侵入的二长花岗岩。成矿温度为中偏高温。成矿溶液为高盐度、高密度和高挥发份条件。为深源岩浆侵入的花岗岩中破碎蚀变岩型金矿。

| Abstract: | Tasti gold deposit is of an altration type in fracture zones. The study of stable isotopes, inclusions and metallogenic elements as well as physical and chemical conditions reveals that the metallogenic fluid is the mixture of magmatic fluid with water and precipitation. The metallogenic fluid is of high salinity, high density and high volatile. The ions of inclusion have the similar composition with those of magmatic hydrothermal gold deposit. In the early metallogenic stage the ore fluid is in an acid oxidization enviroment; in the main metallogenic stage it is in an intermediate reduction enviroment. The gold-bearing fluid moved along the fractured alteration zone, and then concentrated and precipitated to form ore body. |
