Cementation is continuous in the groundwater zone, so much so that the term "zone of cementation" is sometimes used interchangeably. Cementation occurs in fissures or other openings of existing rocks and is a dynamic process more or less in equilibrium with a dissolution or dissolving process.
In the case of pervasive growth, cementation of the host sediments, by infilling of its pore space by precipitated minerals, occurs simultaneously throughout the volume of the area, which in time becomes a concretion. Concretions are often exposed at the surface by subsequent erosion that removes the weaker, uncemented material.
Compactions and cementation generally lead to permeability reduction by losing porosity. [1] When a large region, which consist a fault zone, experience compaction and cementation, porosity loss in host rock (undeformed rock surrounding the fault zone) can be greater than that of fault zone rock. Hence, fluids are forced to flow through a fault ...
Cementation is the diagenetic process by which coarse clastic sediments become lithified or consolidated into hard, compact rocks, usually through the deposition or precipitation of minerals in the spaces between the individual grains of sediment. [4] Cementation can occur simultaneously with deposition or at another time.
Cementation may refer to: Cementation (biology) , the process whereby some sessile bivalve mollusks (and some other shelled invertebrates) attach themselves permanently to a hard substrate Cementation (geology) , the process of deposition of dissolved mineral components in the interstices of sediments
President-elect Donald Trump had not been terribly successful in suing media organizations until this weekend when ABC News agreed to settle a closely-watched defamation case he brought against ...
Drift (geology) – Material of glacial origin; Flocculation – Process by which colloidal particles come out of suspension to precipitate as floc or flake; Longshore drift – Sediment moved by the longshore current; Overbank – Alluvial geological deposit; Sedimentary rock – Rock formed by the deposition and cementation of particles
