Clastic sedimentary rocks are classified based on the dominant particle size. The Udden-Wentworth grain size scale is commonly used by geologists to classify unconsolidated sediment into three fractions: gravel (>2 mm diameter), sand (1/16 to 2 mm diameter), and mud (1/16 mm diameter). Silt (1/16 to 1/256 mm diameter) and clay (1/256 …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, …Sedimentary rocks form whenever these sediments are deposited and lithified and can be classified based on the size of their grains. Gravel forms coarse rocks with grains over 2 mm in size. If the fragments are rounded, they form conglomerate, and if they are angular, they form breccia. Sand, as you may guess, forms sandstone.Molten rock is called magma when it is inside the earth and lava when it is released from a volcano. Fossils are only found in sedimentary rocks. Some rocks like pumice can float on water. The oldest minerals in the world are found in Jack Hills in Western Australia. The mineral is called zircon and it is 4.374 billion years old!Major types of clastic sedimentary rocks are (from fine to coarse constituent clasts): mudstone: clay ("blocky") and shale (splits easily) siltstone sandstone sedimentary conglomerate or breccia. Clastic sedimentary rocks are classified mainly on the basis of texture, with sensible names that refer to the size of material they contain. Clastic sediment is sediment consisting of fragments of rock, transported from elsewhere and redeposited to form another rock. Clasts are individual grains that make up the sediments. The sediment particles are then further exposed to rain, wind, and gravity, which batters and break them apart through further weathering and erosion processes.CLASTIC.
