Sedimentary-tectonic framework and provenance analysis of the late Paleozoic in the northern Ordos Basin
摘要
Abstract
Sedimentary-tectonic characteristics of Ordos Basin are determined by the regional geotectonic background,and the regional geotectonic background limits further the paleo sedimentary-tectonic framework of the basin. According to the study of the development background, the stratigraphic distribution characteristics, the lithology characteristics and the sedimentary-tectonic framework of the late Paleozoic in the northern Ordos Basin, it is held that the sedimentary-tectonic framework of the late Paleozoic in the studied area is mainly affected by the evolution of Xingan Mongolia Trough in the north margin of the basin,and it gradually changed from the EW-trending framework to the NE-SW-trending framework. Based on the previous research results of sedimentary-tectonic evolution, the provenance distribution of the late Paleozoic in the studied area is further studied and its provenance evolution mode is established according to the present tectonic characteristics of the northern Ordos Basin and drilling and outcrop data. It is shown that, from Benxi stage of the late Carboniferous to Taiyuan stage of the early Permian,Yimeng ancient uplift is denudated as the provenance of the northern Ordos Basin,and it had certain barrier effect on the provenance providing of Yinshan ancient land to the northern Ordos Basin;from Shanxi stage of the early Permian to Shiqianfeng stage of the late Permian, with the Yimeng ancient uplift area begining accepting deposition, Yinshan ancient land became the common provenance of the north area of the basin and Daqingshan area in the north margin of the basin.关键词
