| 摘 要： | 新疆柯柯亚地区上石炭统(柳树沟组、齐家沟组、奥尔吐组)硅质岩分布广泛.通过野外地质填图、剖面测制和常量、微量、稀土元素研究,结果表明,这些硅质岩是海底火山喷发多次活动结果研究区硅质岩具高TiO2 、富Ni、贫Co,低K2O、P2O5,Al2O3与TiO2呈正相关,在TiO2-Al2O3双变量图解中,属火山成因硅质岩,δCe与陆缘硅质岩非常接近,形成于大陆边缘环境. |
| 关 键 词： | 柯柯亚 上石炭统 硅质岩 火山成因 大陆边缘 |

| Abstract: | Cherts are wildly distributed in the Upper Carboniferous(Liushugouzu C2l,Qijiagouzu C2q and Aoertuzu C2ae) in Kekeya area of Xinjiang.By detailed field observation in mapping,profile survey,combined with the date of macro-analysis,Ree and other trace elements.The results show that those cherts come from the many times volcanic eruption.The Characteristic of chert such as rich in TiO2 and Ni,But very poor in Co,K2O,P2O5,The AL2O3 varies directly with TiO2,discrimination diagram of biviriates TiO2-Al2O3,belon... |
