| 摘 要： | 东川铜矿田位于云南省东北部昆阳元古宙裂谷中，矿体呈层状、似层状赋存在昆阳群因民组、落雪组和黑山组内．岩石学、矿物学和地球化学的新证据表明，容矿主岩为火山岩、火山碎屑岩和喷流岩系，成矿物质主要来自于地球深部，是通过与火山岩浆活动有关的喷流作用参与成矿的．作者结合矿床地质的研究，建立了东川铜矿的喷流沉积成矿机制．

| Abstract: | Dongchuan Copper Field is located in the Kunyang Proterozoic Rift, Northeast Yunnan,China, whose orebodies with the stratiform and lentiform shapes are hosted in Yinmin Formation, Luoxue Formation and Heishan Formation of Proterozoic Kunyang Group. New petrological, mineralogical and geochemical evidence displays that host rocks are volcanic,pyroclastic and exhalative rock series, ore-forming materials originated mostly from the depth of the earth and are developed into ore bodies by the exhalative sedimentary metallization related to the volcanic magmatic activity. Based on geology research of the deposits,mechanism of exhalative sedimentary metallization in Dongchuan Copper Field is suggested. |
