冀中坳陷蠡县斜坡古近系沙一下亚段沉积物源分析
Provenance analysis of the lower part of Member 1 of Paleogene Shahejie Formation in Lixian Slope, Central Hebei Depression
摘要
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 prove-nances.The southwestern provenance mainly located in the Taihangshan uplift,whose sediments were car-ried 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 prove-nance was dominant while the northern one was minor.Xiliu area was a convergence region of both proce-nances.关键词
