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
盆地基底由前寒武紀結晶基底和古生代褶皺基底組成，盆地蓋層則經歷了二疊紀的裂谷盆地、三疊紀?白堊紀的坳陷盆地和第三紀后的山間盆地的演化過程。盆地主要沉積了下二疊統巨厚火山巖、淺成侵入巖和凝灰巖；中二疊統蘆草溝組的暗色泥巖、泥灰巖、白雲質巖石以及條湖組的巨厚層火山巖、侵入巖；三疊系雜色砂礫巖、砂巖及灰色泥巖（下紅上灰） ；以及侏羅紀厚層深灰、灰色砂礫巖、砂巖、泥巖夾煤層。The gravity drive is interpreted as the major cause of the northerly detachment along the coal layer in the proximity of the t9 boundary
以地震反射特徵的明顯差異為依據，結合區域地質特徵，研究了鄂爾多斯地塊西部南北向基底拆離形成的韋州石溝驛拆離滑覆構造。The further study shows that the sandstones at the bottom of the lower ganchaigou formation, which is a tr lithostratigraphic unit, were deposited in different stages of base level cycle, and they are not chronostratigraphic unit. so, to identify different sequences, especially high order sequences in analysis of terrestrial stratigraphic sequences, the sequence distribution feature must be fully consided. this view has practical significance for recognizing forming, evolution and filling history of qaidam baisn correctly, and has both theorical and practical meaning for directing further oil exploration
研究還表明，傳統巖石地層單位中下乾柴溝組底部的砂巖代表了基準面變化旋迴不同階段沉積的產物，它們屬于不同的成因單位，也非等時地層單位，因此，在進行陸相層序地層分析時，各級層序尤其是高級層序的識別要充分考慮面上的層序展布特點，這一觀點對正確認識柴達木盆地的形成演化和沉積充填歷史，指導今後的勘探具有一定的理論和實際意義。
