The pre-existing rock is called either the parent rock or the protolith. Your textbook incorrectly uses the term “source rocks” for the pre-existing rock. The term source rock used in sedimentary deposits to describe the rock from which petroleum is derived, or the rock that erodes to produce sediment and later sedimentary rock.Updated on January 20, 2019. Sedimentary rocks are the second great rock class. Whereas igneous rocks are born hot, sedimentary rocks are born cool at the Earth's surface, mostly under water. They usually consist of layers or strata; hence they are also called stratified rocks. Depending on what they're made of, sedimentary rocks fall into …

sedimentary rock, it is important to look at the grain size, grain roundness, and grain sorting. Grain Size Classification of clastic sedimentary rocks is based on the average diameter of constituent fragments. Grain size can be divided into four classes (Figure 5-2): (1) Coarse-grained (boulder-, cobble-, and pebble-sized) – larger than 2 mm. Rock Identification Tips. First, decide whether your rock is igneous, sedimentary or metamorphic. Igneous rocks such as granite or lava are tough, frozen melts with little texture or layering. Rocks like these contain mostly black, white and/or gray minerals. Sedimentary rocks such as limestone or shale are hardened sediment with sandy or clay ...Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.THE ROCK KEY Use this key to ask and answer questions on your unknown rock specimens.
