  1. 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。
  2. In this paper, the authors prove the sedimentary environment of every lithostratigraphic unit of devonian, and precisely divide the geomorphic units of petrologic paleogeography of that period, based on the multiple division and detailed study to the petrostratigraphy, biostrtigraphy and sequence stratigraphy of devonian in hubei and its adjacent provinces

    摘要通過對湖北及鄰省泥盆紀巖石地層、生物地層與層序地層進行多重劃分對比和詳細研究,以大量實際資料確定該時期各巖石地層單位的沉積環境,準確劃分出該時期巖相古地理地貌單元。
