摘　　要：运用古今水系对比、轻/重矿物组合比对、岩屑组分分析、砂岩厚度等值线等方法,分析研究区目的层段的物源。结果表明:蠡县斜坡沙一下亚段物源来自斜坡西南部和北部,物源区分别位于西部太行山隆起和北部的牛驼镇凸起,其中西南方向物源为优势物源,北部物源为次要物源,且两者在西柳地区发生交汇。By analyzing ancient and modern water system,light mineral combinations,heavy mineral combinations,lithic component and sandstone thickness contour,the provenance of the lower first member of Shahejie Formation in the Lixian Slop are systematically studied.The analysis result shows that the provenances are mainly derived from the northern and the southwest of the slope.The source areas are Taihang Mountain in the west and the Niutuozhen salience in the north.The southest direction provenance has advantage against the north direction provenance,and the two sources meet together at Xiliu area.
