内蒙古西部额济纳旗及邻区石炭纪-二叠纪盆地重矿物的特征及意义
Heavy mineral characteristics of Carboniferous-Permian strata in Ejin Banner and its vicinities, western Inner Mongolia, and their significance
摘要
Abstract
Aim-to confirm the basin-and-range structural framework evolvement and provenance system of Carboniferous to Permian in Badanjaran basin. Method-by analyzing the content and the combined characteristic of clastic heavy mineral in sections of different depression belts of Carboniferous to Permian. Results-most of the heavy minerals in Badanjaran basin didn't suffer long-distance transport and the heavy minarals combination are different in different secondary units of different periods. In Carboniferous, the combination forms are zircon+apatite in Hongshishan-Heiyingshan depression, zircon+rutile +apatite+tourmaline in Hongliudaquan depression, zircon + rutile+apatite+tourmaline+garnet in Xilinhaote depression with garnet's drastically increasing upwards and zircon+rutile+apatite+ tourmaline in Zhusileng delve. Whereas, in Permian, the combination forms are zincon+apatite+ garnet in Hongshishan-Heiyingshan, zircon+rutile+apatite+tourmaline+garnet in Hongliudaquan depression, zircon + garnet + tourmaline in Xilinhaote depression, zircon+rutile+apatite+tourmaline+garnet in Zhusileng delve. Basin heavily shrinked in Late Permain northwards and marine sedimentary heavy mineral combination is zircon + rutile+apatite + tourmaline. Conclusion-there are two provenance systems in Badanjaran basin,Alashan-Langshan ancient land and Mazongshan slitter palaeohigh.关键词
