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.%为了确定巴丹吉林盆地石炭系-二叠系盆山构造格局和物源体系,分析了巴丹吉林盆地石炭系-二叠系剖面碎屑岩中重矿物的含量和组合特征.结果显示:石炭系红石山-黑鹰山坳陷重矿物组合为锆石+磷灰石,红柳大泉坳陷为锆石+金红石+磷灰石+电气石,锡林浩特坳陷为锆石+金红石+磷灰石+电气石+石榴子石,珠斯棱凹陷为锆石+金红石+磷灰石+电气石;二叠系红石山-黑鹰山坳陷重矿物组合为锆石+磷灰石+石榴子石,红柳大泉坳陷锆石+金红石+磷灰石+电气石+石榴子石,锡林浩特坳陷为锆石+石榴子石+电气石,珠斯棱凹陷为锆石+金红石+磷灰石+电气石+石榴子石.巴丹吉林盆地存在阿拉善-狼山古陆和马鬃山-切刀古隆起2个物源体系.
