depositional system tract meaning in Chinese

沉积体系域

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
层序构成和沉积体系域的发育分布受到盆地形成演化过程中各种构造作用的控制。
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
不同构造演化阶段的层序结构和沉积体系域构成等存在显著差异，主要取决于古构造格架和同沉积构造的活动。
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
构造坡折带是由构造活动所产生的、对沉积作用具有长期控制作用的古沉积斜坡或古地貌突变带，在断陷或前陆等盆地中普遍发育，其识别对阐明盆内沉积体系域，特别是构成重要油气藏的低位域的分布和预测具有重要意义。
