摘要
文章以构造地层学和层序地层学相结合的综合地层学分析方法作为分析龙门山前陆盆地的基础,以不整合面和其对应面作为分割盆地充填序列的基本界面,并按不整合面的规模和性质,将龙门山前陆盆地充填序列分割为6个构造层序和14个层序,初步查明了龙门山前陆盆地充填序列和沉积体系三维空间配置模式及其在时间上的演变,建立了龙门山前陆盆地地层格架和充填模式。
Longmen Mountains foreland basin is one of typic foreland basins and an important petroliferous basin in China. According to the principle of tectostratigraphy and sequence stratigraphy, the filled strata of Longmen Mountains foreland basin can be divided into six tectonic sequences and fourteen sequences by uncomformities. The tectonic sequence can be summarized into two kinds of filling model by the internal texture and distribution pattern of the sedimentary system,including progressive tectonic sequence and retrogressive tectonic sequence.
