摘　　要：结合盆地区域地质背景、岩石类型、重矿物组合等特征，重点应用稀土元素配分模式对鄂尔多斯盆地洛川地区延长组进行了物源分析。结果表明：鄂尔多斯盆地洛川地区的物源主要来自北部大青山地区太古界乌拉尔山群．东部吕梁山和南部秦祈造山带此时并未对其提供物源。In the light of features such as regionally geological background of the basin, the rock type, and heavy mineral combination, source of the Yanchang Formation of Luoehuan area of Ordos Basin was analyzed mainly by the application of REE patterns. The results show that the source of Luochuan area was from the Urals Group of Archean in the DaQingshan area of northern Ordos basin. The Lvliang Mountain in the east and Qinling-Qihan orogenic belt in the south did not provide the source at this time.
