channel deposit meaning in English

河道沉积

In the chronstratigraphic framework , the facies , the depositional system and the principle and range of reservoirs distribution are studied . the main depositional system is braided delta ? ub - lake fan . the coarse lithofacies which form braided delta depositional system is sub - water channel deposits ; the coarse lithofacies which form the sub - lake fan depositional system include turbidity channel deposits and bedded turbidity deposits
在等时地层格架内，总结了各个中期旋回的沉积相类型、沉积体系和展布规律及范围，认为研究区在该时期以辫状三角洲?湖底扇沉积为主；构成辫状三角洲的粗碎屑相为水下分支河道；构成湖底扇的粗碎屑相包括：浊流水道相、层状浊积岩相。
This result lays a solid foundation for the research . 2 . based on the study of petrology facies , facies association and sedimentary sequences , the sedimentary processes and systems are established . they consist of debris and hyper concentration flow deposits , channel deposit of braided and meandering streams , and alluvial fans , floodplains , fan - deltas and lacustrine turbidities
根据岩相、相组合以及沉积层序的研究，确立了研究区的沉积作用类型和沉积体系，它们包括碎屑流和超浓缩洪流沉积、辫状河河道沉积，以及冲积扇沉积、洪泛平原沉积、扇三角洲沉积和湖相浊流沉积。
