Beef and cone-in-cone calcite fibrous cements associated with

Jan 01, 2016 · Most samples cannot provide proof of formation of B-CIC calcite before lithification, but crushed ammonites encased in B-CIC calcite prove these fibrous calcite cements formed after compaction. Thus it is problematic to demonstrate that crystal growth occurred in unconsolidated sediment (critical to the proposal of a novel carbonate factory) in the shallow sea floor soon after deposition, prior to lithification.

Aquarium Chemistry: Calcite, Aragonite, Limestone, and More

So, crushed oyster shell gravel is composed of calcite. Crushed coral gravels. In light of the fact that stony corals use aragonite to build their skeletons, it should make perfect sense that any bags of gravel labeled “crushed coral” are in fact bags of aragonite. However, I’ve also seen many bags of crushed coral gravel that were ...

Origin of bedding-parallel fibrous calcite veins in

Apr 01, 2019 · The fibrous calcite likely precipitated from modified pore water at elevated temperature, which is supported by its low δ 18 O values (−13.7‰ to −11.4‰ VPDB). The veins formed over two stage and the fibrous calcite growth was continuous and at least partly driven by the force of crystallization.

Aragonite - Wikipedia

Aragonite is metastable at the low pressures near the Earth's surface and is thus commonly replaced by calcite in fossils. Aragonite older than the Carboniferous is essentially unknown. [6] It can also be synthesized by adding a calcium chloride solution to a sodium carbonate solution at temperatures above 60 °C (140 °F) or in water-ethanol ...
