4.8: Sedimentary Rocks
Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. Biochemical sedimentary rocks form in the ocean or a salt lake. Living creatures remove ions, such as calcium, magnesium, and potassium, from the water to make shells or soft tissue. When the organism dies, it sinks to the ocean floor ...

sedimentary rock
Sedimentary rock can also be formed when the shells of sea creatures fall to the floor of the sea after the creatures die. When the shells form a thick enough layer they become compressed and form rock. In some places where there are shallow bodies of water another kind of sedimentary rock may be formed. In these cases, if the surrounding air ...

Porosity of the rock matrix also is a function of post-induration processes, such as changes in lithostatic loading, regional and local tectonism, and weathering. Porosities of sedimentary rocks have been shown to vary from less than a percent to > 20% (Dorsch and Katsube, 1999, Pearson, 1999, Bloomfield et al., 2001). Larger porosity in the ...

sedimentary rock
The most common type of rock exposed on Earth's surface is sedimentary rock. However, Earth's crust is formed predominantly of the other two main types of rock, igneous rock and metamorphic rock. Sedimentary rocks are produced by the weathering of old rocks, which breaks apart the rocks into particles or fragments called sediment.

Sedimentary rock is formed over millions of years. It is built up layers. Fossils can be found in sedimentary rock. Fossilisation. If a marine organism dies, falls to the ocean floor and doesn't rot away, it may form a fossil. Over time, sediment is layered on top of it.

Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, and 0.08 inches, …
