| 摘 要： | 阿舍勒多金属矿田，位于阿舍勒陆缘裂陷槽中。矿田构造为两个复式向斜夹一个复式背斜组成的褶皱束，具有６组断裂，经历了３次拉张，３次闭合的演化历史。矿田地层为泥盆系火山岩建造及下石炭统火山－沉积岩建造。中泥盆世艾菲尔期和晚泥盆世弗拉斯期，为矿田的两个主要成矿期。Ⅰ号矿床形成于艾菲尔期，矿体赋存于古火山机构通道相的次辉绿岩筒筒壁间隙之中。

| Abstract: | Ashele multimetal ore field is located at the rift depression of continental margin,characterbod by two synclinoria and one anticlinorium. The six-group fractures in the field show the evolution history of 3-time tension and 3-time closure. The stratigraphy is shown as volcanic formations of Devonian and volcanic-sedimentary formations of Lower Carboniferous. There exist two main ore mineralization stages,i. e,Aifeir stage of Middle Devonian and Feilars stage of Late Devonian. No. 1 ore deposit was formed at the Aifeir stage,with ore body mianly at the in tersetion of sub-diabade cylinder of palaeo-volcanic apparatus phase. |
