| 摘 要： | 对养麦冲金矿进行岩石化学、元素地球化学、包裹体、同位素、稀土元素地球化学研究，揭示了燕山期脆-韧性剪切变形变质作用在金矿成矿过程中的主导作用。矿床成矿期三分，以中期为主，该期成矿环境以温度、氧逸度增高，压力、密度降低为特征，属弱酸-弱碱性介质，弱还原环境。

| Abstract: | By means of studying petrochemistry and geochemitry of inclusion, isotope and element including REE in Qiaomaichong gold deposit, it is revealed that the brittle-ductive shear deformation and metamorphsim play a leading role in the process of the gold metallogenesis and the principal metallogenic epoch is in the medium stage in weak reduction environment with weak acid-weak alkaline medium characterized by higher temperature, higher oxygen fugacity, lower pressure and lower density. |
