Diagenesis - Wikipedia
网页Diagenesis (/ ˌ d aɪ. ə ˈ dʒ ɛ n ə s ɪ s /) is the process that describes physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition.
Diagenesis | Chemical, Physical, Biological | Britannica
网页Diagenesis, sum of all processes, chiefly chemical, by which changes in a sediment are brought about after its deposition but before its final lithification (conversion to rock). Because most sediments contain mineral mixtures in which not all the minerals are in chemical equilibrium with each.
网页DIAGENESIS 1. INTRODUCTION 1.1 Diagenesis is the term used for all of the changes that a sediment undergoes after deposition and before the transition to metamorphism. The multifarious processes that come under the term diagenesis are chemical, physical, and biological. They include compaction, deformation, dissolution, cementation,
What Is Diagenesis in Geology? - ThoughtCo
网页2019年2月22日 · Diagenesis is the name for a wide range of changes that affect sediments during their progress to become sedimentary rocks: after they are laid down, while they are becoming rock, and before they first undergo metamorphism.
8: Diagenesis - Geosciences LibreTexts
网页Diagenesis is the process that transforms sediment into sedimentary rock. The most important diagenetic processes are compaction (reduction in volume) and cementation (precipitation of mineral …
Diagenesis - an overview | ScienceDirect Topics
网页Diagenesis is defined as the physical and chemical changes that occur when sediment is transformed into sedimentary rock, involving processes such as mineral dissolution, precipitation, and microbial reactions within the Earth's crust.
Diagenesis of Sedimentary Rocks - Geology Science
网页2023年4月23日 · Diagenesis is the process by which sedimentary rocks are altered after they are deposited, but before they are buried and lithified (turned into rock). This process involves physical, chemical, and biological changes that can affect the mineralogy, texture, and other properties of the sedimentary rock.
Diagenesis - SpringerLink
网页2018年1月1日 · Diagenesis involves both the conversion of sediments into sedimentary rock and the subsequent changes that occur prior to entering the metamorphic realm. There is no distinct boundary between the culmination of diagenesis and the onset of metamorphism nor between early diagenesis and weathering.
Diagenesis - SpringerLink
网页Diagenesis encompasses all the physical and chemical processes that affect sediments and sedimentary rocks in the portion of the rock cycle that includes the period of burial between deposition and weathering, and also between deposition and the onset of metamorphism.
Diagenesis - SpringerLink
网页2018年1月30日 · Diagenesis is the sum total of processes that occur following deposition of a sediment up to but excluding metamorphism. It includes compaction, mineral precipitation, mineral dissolution, and mineral transformation.
