摘　　要：结合前人研究,本文通过重矿物分析,发现延安以南以及永坪以北的锆石、石榴子石及白钛矿含量有明显差别,得出研究区山西组存在南北两个主要物源方向,进一步分析还可将北物源分为两部分。By theanalysis of the heavy minerals, this paper shows that the contents of zircon,garnet and leucoxene in south of Yan-an are different from that in north of Yongping. It concludes that there are mainly two sediment source regions in Shan-xi formation. Further, the north sediment source can he divided into two different regions.
