The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals. The above classification scheme is the most commonly used and accepted, though sometimes an older system is used which divides iron-rich sedimentary rocks into three categories: bog iron deposits, ironstones, and iron formations. A bog-iron deposit is iron that formed in a bog or swamp through the process of oxidation.This will build a foundation while understanding the rock cycle. There are 3 main types of rocks i.e. the igneous rocks, sedimentary rocks, and metamorphic rocks. Rocks are classified according to the way they are formed. We consider factors such as hardness, cleavage ( how the rocks split), lustre ( how shiny it is), colour, texture, etc.Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals.
