Georgia’s rocks and geological structures define the shape and relief of the land, providing the topographic … 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 … See more • Chalcedony – Microcrystalline varieties of silica, may contain moganite as well • Chert – Hard, fine-grained sedimentary rock composed of cryptocrystalline silica See more Diagenesis alters the proportions of organic collagen and inorganic components (hydroxyapatite, calcium, magnesium) of … See more
