Mg isotopic systematics during early diagenetic aragonite ...
· The aragonite and calcite endmembers have distinct Mg isotopic compositions, suggesting significant fractionation during this process, involving with aragonite dissolution (no fractionation) followed by calcite precipitation (large fractionation). In addition, Mg isotopes of calcite show a wide range of variation (~1‰), suggesting either a change in the fractionation factor or a change in ...

Techniques for Collectors : Calcitearagonite test
· The easiest and fool proof test to distinguish calcite from aragonite is using Feigl's solution. A sample of aragonite placed in Feigl's solution will turn black in less than 30 minutes ( at room temp.), whereas calcite will take at least 10 times as long to turn black, if at all. To make sure my solution is still good a always add a known sample of calcite and aragonite as standards when ...

Production and characterization of synthetic aragonite ...
In this paper, we investigate the influences of these experimental conditions on the production of synthetic aragonite crystals from dolomite using a leaching carbonation process. The proposed process is believed so be more ecofriendly than other methods suggested in the literature because the CO2 released from the dolomite during the leaching stage is stored for use in the carbonation stage ...

Impact of skeletal dissolution and secondary aragonite on ...
· Aragonite is, however, metastable in the marine environment. Early diagenesis can occur as dissolution and/or infilling of vaed skeleton with secondary aragonite Constantz, 1986]. In this paper we show, for the first time, that both dissolution and secondary aragonite influence a wide range of tracers that are commonly measured in coral skeletons (density, δ 13 C, δ 18 O, Sr/Ca, U/Ca, and ...

A Brief review of Aragonite Precipitated Calcium Carbonate ...
Generally, aragonite is synthesized by two methods: carbonation process [1720], and solution process [21,22], as shown in Fig. 2. Among which, carbonation is being widely used because of its industrial importance. Extensive research has been done based on synthesis of calcium carbonate for many decades in water systems.

Aragonite: Meanings, Properties and Powers
Aragonite does not score very high on the hardness scale. So if you wish to clean your Aragonite stone, avoid using mechanical cleaners like steam and ultrasonic processes. What you can do instead is to use a soft brush, warm water, and mild detergent to clean it. Wipe your Aragonites dry with a soft cloth to remove all traces of water. Make sure that you store your Aragonites separately from ...

Mystery solved: Why seashells' mineral forms differently ...
· For almost a century, scientists have been puzzled by a process that is crucial to much of the life in Earth's oceans: Why does calcium carbonate, the tough material of seashells and corals, sometimes take the form of calcite, and at other times form a chemically identical form of the mineral, called aragonite, that is more soluble — and therefore more vulnerable to ocean acidifiion?

Crushed coral vs Aragonite
· Aragonite sand comes in a wide selection of grain sizes nowadays – from extremely fine grains to large ones suited for tanks with a strong water flow. This is very handy because you get to choose the size that works best for your tank. For example, if your tank has a high flow, avoid very fine sand unless you're a fan of sandstorms. Compared to crushed coral, aragonite sand is much easier ...
