| 摘 要： | 重点阐述了川西北地区浅成低温热液金矿系列所经历的四个主要成矿阶段，即金的初始沉积预富集阶段，金的改造预富集阶段、金的叠加改造工业富集阶段和金的剥蚀氧化阶段的区域成矿地质背景，提出了拉日玛式、东北寨式、丘洛式和大水式微细浸染型金矿的分类方案与划分依据；探讨了区域金矿的层控规律、时控规律、岩控规律与构造控矿规律。

| Abstract: | Regional geological setting for 4 ore-forming stages of epithermal An deposits in northwest Sichuan is expounded. The 4 ore-forming stages are sedimentary primary pre-enrichment, reformation pre-enrichment, superimposed pre-enrichment adn denudation-oxidation stages. The fine disseminated type Au deposits may be divided into Larima, Dengbeizhai, Qiuluo and Dashui subtypes. Stratabound and timebound characters, lithological and structrual controls are discussed. |
