1.sedimentary rock is a type of rock that is formed from substances that have been left by water, wind, or ice and have become pressed together through time. The other types of rock are igneous rock and metamorphic rock.
1.The sedimentary features and strata touching relation in the Early-middle Mesozoic of Helanshan area were contrast to that of Ordos Basin.
贺兰山地区中生代早中期的沉积特征及地层接触关系与鄂尔多斯盆地内部相一致；
2.A very common sedimentary rock is called shale, which is a soft rock and was obviously formed by being deposited on the sea bed.
一块极普通的沉积岩叫页岩，这种页岩质地松软，很明显是通过海底沉积作用形成的。
3.It has special physical and mechanical properties due to its composition, structure and sedimentary environment.
特殊的发育环境、物质组成和结构导致了珊瑚砂具有独特的物理力学性质。
4.If there are a lot of reflections and resonances near the point (for instance in a sedimentary valley) the shaking will last longer.
如果在那点附近有很多反射和共振（比如在沉积山谷），震动会持续得更长。
5.If sedimentary rocks are any guide , such a low fluid content would have a negligible effect upon the structural integrity of the material .
如果沉积岩是有任何定向的话，这种低的流体含量对物质结构的完整性几乎不起作用。
6.For the second situation, fault is usually middle or small scope, and develops in sedimentary covers widely.
另一种为重力成因，多为中、小型规模，且广泛发育于沉积盖层中。
7.On Earth, the deposit of sedimentary rock at the bottom of the ocean is part of larger geological cycles.
在地球上，海底沉积岩的累积，也正是更大范围的地质循环的一部分。
8.This fundamental truth is one of the cornerstones of the sedimentary-organic theory for the origin of hydrocarbons.
这一重要事实，是有关碳氢化合物起源的沉积-有机理论的论证基础之一。
9.We use the dip logger to determine the direction of flow, sand body extension, stratification structure and sedimentary characteristics.
