1·Attempts were made to calculate Earth's age from the thickness of surviving sedimentary rock and from the current level of the oceans' salinity.

人们曾试图根据现存沉积岩的厚度和目前海洋的盐度水平来计算地球的年龄。

2·Sedimentary rocks—the most common rock type near the surface—are also the most common reservoirs for water because they contain the most space that can be filled with water.

沉积岩——地表附近最常见的岩石类型——也是最常见的储水层，因为它们可以装水的空间最多。

3·Concepts of sedimentary rock.

沉积岩的一般概念。

4·Texture of sedimentary rock: clastic texture and nonclastic texture.

沉积岩的结构：碎屑结构和非碎屑结构。

5·Bedding is the most important structural feature of sedimentary rock.

层理是沉积岩最主要的构造特征。

6·Sedimentary rock layers are always characterized by a particular seismic response.

沉积岩地区，总是以一种独特的地震响应为特征的。

7·Likewise, the layered beds on Mars may be sedimentary rock formed in ancient lakes and seas.

所以火星的千层榚地貌，很可能是古湖或古海沈积物所形成的沈积岩。

8·The lithology is mainly composed of lava basalt, pyroclastic rock and volcanic sedimentary rock.

其岩性主要为熔岩类玄武岩，火山碎屑岩和火山沉积岩；

9·Coal is a sedimentary rock composed principally of organic carbonaceous macerals and inorganic minerals.

煤是一种有机沉淀岩，主要包括有机碳化合物和无机矿物。

10·The organic matter abundance of sedimentary rock is low, and there is basically no effective source rock.

沉积岩的有机质丰度低，基本无有效生油岩发育。
