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。
