Diagenesis is the process that describes physical and chemical changes in sediments first caused by water-rock interactions, microbial activity, and compaction after their deposition. Increased pressure and temperature only start to play a role as sediments become buried much deeper in the … See more The term diagenesis, literally meaning "across generation", is extensively used in geology. However, this term has filtered into the field of anthropology, archaeology and paleontology to describe the changes and alterations that … See more When animal or plant matter is buried during sedimentation, the constituent organic molecules (lipids, proteins, carbohydrates and lignin-humic compounds) break down due to the increase in temperature and pressure. This transformation … See more Diagenesis alters the proportions of organic collagen and inorganic components (hydroxyapatite, calcium, magnesium) of … See more • Chalcedony – Microcrystalline varieties of silica, may contain moganite as well • Chert – Hard, fine-grained sedimentary rock composed of cryptocrystalline silica • Flint – Cryptocrystalline form of the mineral quartz See more WebDiagenesis is considered a relatively low-pressure, low-temperature alteration process, whereas metamorphism is considered to be a rock-alteration process occurring at …
WebJan 1, 1979 · This chapter discusses diagenesis of sediments and rocks. Diagenesis are defined as the changes that occur in the character and composition of sediments, beginning from the moment of deposition and lasting until the resulting materials are moved into the realm of metamorphism or become exposed to the effects of atmospheric weathering. Webbig group of information reflects post-sedimentary transformation of the rock. Such a process, called diagenesis, is characterized by elevated temperature and pressures. In fact, when chemical, structural, and isotopic composition of minerals, organic matter, and/or whole rocks are determined, estimations of the conditions of transformation
