About AragoniteHide

Formula:
CaCO3
Colour:
Colorless to white or grey, often stained various hues by impurities, such as blue, green, red or violet; colourless in transmitted light.
Lustre:
Vitreous, Resinous
Hardness:
3½ - 4
Specific Gravity:
2.947
Crystal System:
Orthorhombic
Member of:
Name:
Named in 1797 by Abrahan Gottlob Werner for the type locality, the village of Molina de Aragón, Spain, and not the province of Aragón, a mistake made by several later writers.
Aragonite Group.
The Ca analogue of strontianite.

The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite). It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions. It is metastable relative to calcite and often converts to calcite accompanying changes in the environment. It is nearly always a low-temperature, near surface mineral.

Aquilano et al. (2023) suggest a re-examination of the polymorphic calcite-aragonite system due to (overlooked) homo-epitaxy.

Aragonite Satin SparA gem name for a fibrous variety of aragonite.
Cobalt-bearing AragoniteA variety of aragonite containing Co2+ replacing Ca.

May appear visually similar to cobalt-bearing calcite or cobalt-bearing dolomite.

Usually occurs as a secondary phase in ore deposits containing primary Co minerals.
CtypéiteCtypéite was introduced by the French mineralogist Alfred Lacroix in 1898 for a white or yellowish aragonite that occcurred with the pisolite habitus (pisolitic aragonite).
Flos FerriA helictitic, sometimes coral-like variety of Aragonite.

Originally reported from Styrian Erzberg, Eisenerz, Styria, Austria.
Lead-bearing AragoniteTraditionally called 'tarnowitzite', much 'tarnowitzite' has been identified as a mixture of aragonite and cerussite, but lead-bearing aragonite with up to 3% PbCO3 may be homogeneous.

Originally reported from Tarnowskie Góry (Tarnowitz), Upper Silesia...
PelagositeA variety of pisolitic aragonite

It consists of hard, shiny, dark coatings on rocky substratum, produced by the action of
cyanobacteria where the supralittoral rock is frequently wetted by sea aerosol.
