Lithification deposition
WebLITHIFICATION: In the process of going from unconsolidated clasts/ sediment or crystals to sedimentary rocks, sediments are compacted and cemented. During compaction, clasts are forced together and some of the water in the sediments is driven out. Web5.3.1 Lithification and Diagenesis Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.

Webstromatolite, layered deposit, mainly of limestone, formed by the growth of blue-green algae (primitive one-celled organisms). These structures are usually characterized by thin, alternating light and dark layers that may be flat, hummocky, or dome-shaped. http://www.columbia.edu/~vjd1/sed_rx.htm
WebThe lithification event associated with carbonate dissolution and reprecipitation is reflected by a distinct strontium anomaly in the pore waters at a hundred to a few hundreds of meters subsurface depth (Figs. 9.3 and 9.24).The Sr 2+ concentration of biogenic calcite is three to five times higher than that of the inorganic calcite reprecipitated from solution (Baker et … WebLithification (from the Ancient Greek word lithos meaning 'rock' and the Latin -derived suffix -ific) is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock. Essentially, lithification is a process of porosity destruction through compaction and cementation.
WebDiagenesis. Diagenesis is defined in the Glossary of Geology (Jackson, 1997) as “All the chemical, physical, and biologic changes undergone by a sediment after its initial deposition, and during and after its lithification, exclusive of surficial alteration (weathering) and metamorphism…. WebDeposition takes place where the conditions change enough so that sediments being transported can no longer be transported (e.g., a current slows). Burial occurs when more sediments are piled onto existing sediments, and layers formed earlier are …
