河东煤田离柳矿区石炭-二叠系沉积地层及岩石特征

Stratigraphy characteristics of the Carboniferous-Permian in Liliu District,Hedong Coalfield

鄂尔多斯盆地东部河东煤田离柳矿区,出露的石炭系地层包括上石炭统本溪组C2b和太原组下段C2t,二叠系出露的地层包括下二叠统太原组上段P1t、中下二叠统山西组P1-2s、中二叠统下石盒子组P2x和中上二叠统上石盒子组P2-3s,运用野外实测剖面和新的地层划分方法,本文对该区苏村-毛港剖面石炭-二叠系沉积地层进行详细的地层学研究.

In the Hedong Coalfield of east Ordos basin,Carboniferous stratigraphy includes the Upper Benxi Formation and Taiyuan Formation,while the Permian stratigraphy contains the Lower Taiyuan Formation,Middle-Lower Shanxi Formation,the Lower Xiashihezi Formation and Middle-Upper Shangshihezi Formation. We explore the detailed stratigraphy research in Sucun-Maogang section from Carboniferous to Permian by using field measured sections and the new stratigraphic classification method.
