| 摘 要： | 本文在对小秦岭金矿脉、围岩、石英中气液包裹体等采取27个氢氧同位素样品并进行测试分析的基础上,论述了该金矿的氢、氧同位素组成特征及其成因意义,认为该金矿的成矿溶液可能是以大气降水为主,同时有岩浆水和变质水参加的混合水。这为该金矿床应属与燕山期构造及岩活动有关的层控矿床这一成矿理论提供了同位素方面的依据。

| Abstract: | Based on the determination and analysis of 27 isotopic samples of Hydrogen and oxygen from the mineral veins, the surrounding rocks and the fluid inclusions in quartz in the Xiaoqingling goldfield, this paper expounded the characteristics of the isotopic compositions of hydrogen,and oxygen and their genetic meaning in the goldfield.The writer holds that the mineralizing fluid may be a kind of mixed water which mainly consists of the atmospheric water,partly the magma-tic water and the metamorphic water .This paper provides an isotopic evidence for the metallotect theory on the strata-bound deposit,in which the gold-bearing beds should be related to the tectonization and the magmation during the Yanshan Stage. |
