Lithogenous material in marine sediments
WebAbstract The prokaryotes (bacteria) comprise the bulk of the biomass and chemical activity in sediments. They are well suited to their role as sediment chemists, as they are the right size and have the required metabolic versatility to … WebThere are four kinds of marine sediments, Lithogenous, biogenous, hydrogenous and cosmogenous. Lithogenous are from the land, they form through the weathering process and are composed of small particles from weathered rock and volcanic activity. And …

WebThe sediment can consist of terrigenous material, which originates on land, but may be deposited in either terrestrial, marine, or lacustrine (lake) environments, or of sediments (often biological) originating in the body of water. Terrigenous material is often supplied by nearby rivers and streams or reworked marine sediment (e.g. sand ). WebThe following classification of the marine sediments is, therefore, based on the basic sources: (a) Lithogenous Sediment (c) Hydrogenous Sediment (b) Biogenous Sediment (d) Cosmogenous Sediment ADVERTISEMENTS: (a) Lithogenous Sediment: The word ‘lithogenous’ means derived from rocks.
