摘　　要：传统的中新元古狼山-渣尔泰山裂陷槽东起渣尔泰山以东,西至狼山一带,是华北陆块北缘西段最重要的有色金属、贵金属及铁矿成矿带。经综合对比研究认为,在其西部的巴音诺尔公等地区发育有相似的中新元古界沉积地层及相应的地质事件,从而初步确定狼山-渣尔泰山裂陷槽向西延至阿拉善右旗的巴音诺尔公地区,扩大了原狼山-渣尔泰山裂陷槽的范围近1/3,该研究成果不仅具有重要的地质意义,同时对地质找矿具有很好的指导意义。Neo-proterizoic Alashan-Zhaertaishan firing system starts from the east of eastern Zhaertaishan and stretches to Langshan＇s west. The rifting system is a very important as nonferrous metal, precious metal, and iron metallogenie belt. Integrated analyses and studies rind that the rifting system can extend west in Bayinnuo, Alashan area. The evidences are that there are neo-proterizoie sedimentary rocks in Bayinnuo since these sedimentary rocks have similar characteristics with those in Zhaiertaishan, and had undergone similar events. This paper infer that Alashan platform and northern China Craton occur as a whole craton before meso-proterozoic Langshan-Zhaertaishan firing system, and are promising for more deposits in Alashan area.
