沉积体系域 meaning in English
depositional system tract
Examples
- 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。 - Comprehensive analysis by combination of basin tectonism during basin formation and evolution with the basin filling and reforming is the key to reveal the configuration of depositional systems and the source , reservoir and seal in the inland tectonically active basins
摘要结合盆地形成演化过程中各种构造作用与盆地沉积充填和改造过程的成因分析，是揭示内陆构造活动盆地沉积体系域时空配置和生储盖发育分布的重要基础。 - 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。 - Abstract : on the basis of a study of sequence stratigraphy , with the systems tract and related boundaries as the mapping unit and using the systems tract condensation method and instantaneous map production method , the authors have compiled the permian sequence paleogeographic map of southwestern china and systematically elucide the characteristics of the permian sequence paleogeographic evolution of the region
