<中国地质>2007年34卷3期发表关于鄂尔多斯盆地石油、煤、含铀砂岩及其围岩的氯仿沥青Sm-Nd同位素研究的文章.潘爱芳等人指出赋存于同一套地层中的含铀砂岩沥青、煤沥青及石油沥青均具有富集地幔特征.笔者通过对其同位素数据重新计算厘定,得出其物质来源是盆地基底变质重熔与年轻物质混合的产物,以壳源为主且与富集地幔无关的结论.

"Sm-Nd isotope study of chloroform bitumen in various energy minerals of the Ordos basin" written by PAN Ai-fang et al. was published in "Geology in China" in 2007. They concluded that chloroform bitumen of various energy minerals in Caboniferous-Jurassic strata was derived from the enriched mantle on the basis of Sm-Nd isotopic compositions of chloroform bitumen in oil, coal, uranium-bearing sandstone and their country rocks in the Ordos Basin. Nevertheless, based on re-calculation by corrected methods, the authors have reached the conclusion that the chloroform bitumen resulted from the mixture between the anatexis products of the basin's basement and the younger accreted materials from the depleted mantle, rather than from the enriched mantle.
