  • Sedimentary Rocks - an overview ScienceDirect Topics

    Miner's observations of the succession of sedimentary rock layers they saw and quarried below the Earth's surface gave birth to a domain, viz. stratigraphy, and an understanding of sedimentary rocks. Berry (1968 , 1987) discusses—from a historical perspective, the geological timescale—how an economic imperative became a significant force in

    These rocks are of basic two types – clastic rocks, which are formed by pressing together of broken particles called clasts; and biochemical sedimentary rocks, that are formed by the action of chemical and biological forces. The texture of a sedimentary rock indicates the various types and sizes of clasts that are a part of the rock.
