摘要: 基于对冀中坳陷饶阳凹陷蠡县斜坡碎屑岩分析化验资料,结合该区古水系与古地貌特征,从岩样的碎屑组分、岩屑类型、重矿物组合与ZTR指数及地震剖面反射特征等方面,对古近系沙河街组一段下亚段(沙一下亚段)沉积的物源方向进行综合研究。结果表明:蠡县斜坡古近系沙一下亚段的沉积物主要来自于斜坡西南部和北部,其中西南部物源区主要位于太行山隆起,沉积物分别由古大沙河经由斜坡南部及古唐河越过高阳低凸起运移进入斜坡,是主要物源;北部物源主要来自牛驼镇低凸起,是次要物源。西南部物源与北部物源交汇于蠡县斜坡东部西柳地区。

Abstract: Based on the testing data,the provenance was determined according to the palaeodrainage pattern and palaeomorphology,clastic components,lithic fragment types,heavy mineral assemblages and ZTR index and seismic profile features. The results show that the sediments of the lower part of Member 1 of Paleogene Shahejie Formation in Lixian Slope mainly derived from the southwestern and northern provenances. The southwestern provenance mainly located in the Taihangshan uplift,whose sediments were carried by the ancient Dashahe river through the southern slope,and the ancient Tanghe river cross Gaoyang low uplift. The northern provenance mainly located in the Niutuozhen low uplift. The southwestern provenance was dominant while the northern one was minor. Xiliu area was a convergence region of both procenances.

Key words: Lixian Slope, Paleogene Shahejie Formation, palaeodrainage and palaeomorphology, heavy mineral assemblages, provenance analysis
