文摘:运用层序地层学原理，对华南二叠纪含煤盆地和侏罗纪鄂尔多斯含煤盆地进行研究，建立了被动大陆边缘盆地和陆相坳陷盆地的地层层序沉积模式和层序聚煤模式，并对两者聚煤作用作了简要对比。 - The basement of the basin is consist of precambrian crystal basement and paleozoic folding basement , while the cover has undergone the evolution of intra - continental rife in permian , down warped basin in triassic - cretaceous period and inter - mountains basin in tertiary . the main sediments are huge - thick volcanic rock , shallow intrusive rock and tuff in early permian , dark mudstone , marl and muddy dolostone in lucaogou formation in middle permian , huge thick volcanic rock , intruder in tiaohu formation in middle permian , miscellaneous sandy gravel , sandstone and gray mudstone in triassic ( the red is under the gray , and huge - thick dark gray , gray sandy gravel , sandstone , mudstone with coal layer in jurassic
盆地基底由前寒武纪结晶基底和古生代褶皱基底组成，盆地盖层则经历了二叠纪的裂谷盆地、三叠纪?白垩纪的坳陷盆地和第三纪后的山间盆地的演化过程。盆地主要沉积了下二叠统巨厚火山岩、浅成侵入岩和凝灰岩；中二叠统芦草沟组的暗色泥岩、泥灰岩、白云质岩石以及条湖组的巨厚层火山岩、侵入岩；三叠系杂色砂砾岩、砂岩及灰色泥岩(下红上灰) ；以及侏罗纪厚层深灰、灰色砂砾岩、砂岩、泥岩夹煤层。
