Sedimentary rocks can be broadly classified into three main types based on their origin and characteristics: clastic, chemical, and organic sedimentary rocks. Clastic Sedimentary Rocks: Clastic rocks are formed from the accumulation and lithification of fragments of other rocks and minerals, known as clasts. These clasts are typically ...5.3: Sedimentary Rocks Sedimentary rock is classified into two main categories: clastic and chemical. Clastic or detrital sedimentary rocks are made from pieces of bedrock, sediment, derived primarily by mechanical weathering. Clastic rocks may also include chemically weathered sediment. They are classified by grain shape, grain size, and …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, …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.

detrital sedimenty rocks are solid products of weathering and often times classified based on their texture How are chemical sedimentary rocks classified? (soluble material produced largely by chemical weathering) Chemical sedimentary rocks derive from ions that are carried in solution to lakes and seas, which then precipitates to form chemical ...Clastic sedimentary rocks are classified according to the grain size of the sediment and the kinds of rock fragments that make up the sediment (Table ).
