How is sedimentary rock classified.

Sedimentary rocks can be classified in two broad categories: clastic and chemical. Clastic Sedimentary Rocks are made from the fragments of eroded bedrock and sediment, which is usually derived from physical weathering. We classify clastic rocks by their grain size, shape, and sorting. Jul 28, 2017 · Detritus, or the rock and mineral particles that are moved by gravity, water, ice, or wind, forms the basis of detrital sedimentary formations. Grain size is used to classify detrital deposits. The size of the grain is used to categorize debris. Gravel is a term for grains that are larger than 2 millimeters. The word clast means rock fragment; the word is derived from the Greek word klastos which means broken. Gravel, sand, and silt are examples of clastic sediments. Lithogenous sediments (described above) are mostly clastic sediments. A classification of clastic sediments and sedimentary rocks is illustrated in Figure 6.39 and with details ...Shale is an argillaceous rock, and argillaceous rocks are "detrital sedimentary rocks" [1]. They are composed of clays and the bedding plane within the shales is "due to the orientation of the clay minerals" [1]. Clearly a sedimentary rock. Coal however, as you state in your question is derived from organic material - vegetation.

Sedimentary rocks are found covering a majority of the Earth’s upper crust. Formed from the deposition of mud and sand that is buried and compressed to form solid rock, sedimentary rocks usually begin their life underwater, rising to the Ea...There are two major groups of sedimentary rocks: 1) siliciclastic and 2) chemical and organic.

Most fossils are found in sedimentary rocks; exceptions are specimens found in metamorphic rocks that were once sedimentary (e.g., fossil shells in marble) or those found in ice (e.g., remains …

Metamorphic rocks are classified by their structure and their dominant minerals. Metamorphic rock structure is either foliated (has a definite planar structure) or nonfoliated (massive, without structure). Metamorphic rocks include slate, phyllite, schist, and gneiss. Sedimentary rocks are layered rocks that are composed of accumulated sediments.Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic material. There are three different types of sedimentary rocks: clastic, organic (biological), and chemical.

Conglomerates ...

Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, mass movement, or glaciers. Some examples of sedimentary rocks are limestone, sandstone, siltstone, shale, conglomerate, and breccia. Most sedimentary rocks contain either quartz or calcite.

Clastic (or detrital) rock is classified and named based on the size and composition of the clasts. Their various sizes, from boulders to clay, is referred to as the sediment grain size. The classification and description of the various clastic rocks appears in the top section of the chart below.
