| 摘 要： | 金矿化与蚀变超基性岩体的空间关系、矿化特征、蚀变超基性岩体、成矿流体、微量元素、硫同位素组成、表明金主要来源于金厂蛇纹石化、滑石化、碳酸盐化超基性岩体。在岩体蚀变过程中，在碱性相对还原的介质条件下，金主要以硫络合物的形式进入成矿溶液，在Ｔ、Ｐ、ＰＨ、Ｅｈ等物理化学参数发生变化的条件下沉淀。

| Abstract: | The spatial relation between the Jinchang altered ultrabasic pluton and gold mineralization,the nature of metallization,geology of pluton, fluid,trace clements and sulfur isotope indicate that gold mainly originated from the Jinchang pluton with serpentization,talcization and carbonatization.During the alteration process,gold was extracted into solution as sulfur complex under the conditions of alkali and reduction,and was deposited with change of physico-chemical parameters,such as T,P,pH,Eh etc. |
