The sequence architecture and the distribution of depositional systems tracts were mainly controlled by a variety of tectonic activities during the formation and evolution of the basins 層序構成和沉積體系域的發(fā)育分布受到盆地形成演化過程中各種構造作用的控制。
The sequence units formed in different evolutional stages of basin show significant difference in sequence architecture , in depositional systems tracts and in sedimentary disposal patterns , which were predominantly determined by the paleo structural framework and the activation of syndepositional structures in the basins 不同構造演化階段的層序結構和沉積體系域構成等存在顯著差異,主要取決于古構造格架和同沉積構造的活動。
The structural slope - break zones are defined as the depositional slopes abrupt change in geomorphology and developed widely in fault and foreland basins , the recognition of which is significant for predicting the distribution of depositional systems tracts , particularly the lowstand systems tracts which usually comprised economically important reservoirs in these basins 構造坡折帶是由構造活動所產(chǎn)生的、對沉積作用具有長期控制作用的古沉積斜坡或古地貌突變帶,在斷陷或前陸等盆地中普遍發(fā)育,其識別對闡明盆內沉積體系域,特別是構成重要油氣藏的低位域的分布和預測具有重要意義。
