| 摘 要： | 研究表明，霍各乞大型铜多金属矿田的Ｃｕ、Ｚｎ、Ｐｂ、Ｆｅ主要来自海底火山喷溢，部分来自海水对基底岩系的淋滤；Ｓ主要来自海水ＳＯ２－４的还原，少部分来自地幔；从微量元素、稀土元素、同位素等方面论证了霍各乞矿田中元古宙为大陆边缘弧后裂谷盆地构造环境。

| Abstract: | The large sized Huogeqi polymetallic orefield is located in the northen part of the Langshan Mountains. Geochemical study showing that Cu,Zn,Pb,Fe were mainly originated from submarine volcanic eruption, and secondly from brine leacheaing of basement rocks, and that S mainly from reduced SO -2 4 in sea water and secondly from mantle. The studies of microelement, rare earth element and isotope compositions that the Huogeqi polymetallic ore field was formed in rift basin of back arc continental marging during Proterozoic Era. |
