摘要: 对鄂尔多斯盆地石油中沥青的微量元素和稀土元素地球化学特征研究表明,鄂尔多斯盆地石油中沥青富集铁族元素、亲硫元素和碱金属元素,相对贫含稀有稀土元素和放射性元素,稀土元素比值接近上地壳及中国沉积岩的稀土元素特征,反映其并非全是.上地壳沉积岩中的有机质的聚集,还应有部分深部物质的加入。

Abstract: Geochemical characteristics of trace elements and rare earth element (REE) of oil bitumen in Ordos basin are studied, and results show that such oil bitumen is rich in trace elements of iron group, sulphur group and alkali metals, relative absence of REE and radioactive element. The REE is similar to those of upper crust and Chinese sedimentary rock, indicating that the original materials for forming oil in Ordos basin are not only from organic matter of upper crust, but also partly from deep materials.

Key words: Ordos basin, oil, bitumen, geochemistry
