Channel deposits, consisting of sand, silt and clay, fill the valleys cut by a river system . 河道沉积由砂,粉沙和粘土组成,充填于河流切割的河谷之中。
More commonly though, the sulfide is restricted to solid aggregates filling the space between the paths . 硫化物通常只局限为固体集结物充填在这些途径中间。
Gouge or infilling is the material between two faces of a structural discontinuity such as a fault . 断层泥或充填物是指一个不连续面(如断层)的两个表面之间的物质。
The cement paste covers the surface of the stones and sand particles, binding them together when it hardens . 水泥浆充填盖满石子和砂粒的表面,硬化时将它们胶结在一起。
The main valley-fill unit, which is above 450 km wide and 15 m thick, trends north-south and has been traced for 40km . 主要的河谷充填砂岩单元,宽在450公里以上,厚15米,往南北方延伸。已跟踪约40公里。
Individual sand bodies, filling erosional features cut by a river, may be elongate or arcuate depending on the course of the river . 充填在河流切割形成的侵蚀地貌中的各个砂体,在形状上可以是伸长状的或弓形的,这要决定于河流的河边。
The latter sedimentary feature is common in estuaries where the development of cut-and-fill deposits of sand is strongly influenced by tidal movements . 后一种沉积特征在港湾内很普遍,在那里沙层沉积的切割和充填的发育受到潮汐运动的强烈影响。

The channel sand is not of the cut - and - fill type 水道砂岩不是切割- -充填类型的。
