| 中文摘要: |
| 七宝山金铜矿床产于鲁东胶莱坳陷西南缘,沂沐断裂带东亚带,受中生代破火山口内隐爆角砾岩筒的控制。本文较系统地论述了该矿床微量元素、同位素、流体包裹体地质地球化学特征,认为成矿与橄榄安粗岩系火山—侵入杂岩关系密切,成岩、成矿物质同源,均来自上地幔或下部地壳,矿化发生在中低温浅成条件下,属次火山中低温热液矿床。 |
| 英文摘要: |
| Qibaoshan Au-Cu deposit is situated in the East sub-belt of Yishu Fracture in southwestern margin of Jiaolai Depression, East shandong province. It is controled by a blind exploded breccia pipe in a crater of Mesozoic age. This paper deals with systematicaly microelements, isotopes,fluid inclusion and geochemistry of the deposit. A conclusion is drawn that ore and the enclosing rock are of the same source of upper mantle and lower crust and metallogeny is closely related to woodendite volanic intrussive complex. The ore was formed under super-medium-low temperature condition. |
