Aragonite is a carbonate mineral and its formula is calcium carbonate. It has the same formula as Calcite and Vaterite, but has a different crystal structure. They are tabular, prismatic or needle-like, …
Aragonite has come from Austria in a Siderite mine in Eisenerz, Styria (mainly in the Flos Ferri variety), and in the salt mines of Salzburg. The old iron mines at Frizington, …
Photos of Aragonite (4765) Aragonite Group. The Ca analogue of strontianite. The principal member of the Aragonite Group, aragonite is the second most common polymorph of …
Aragonite structure easily accomodates Ba, Pb, Sr and Zn. It forms solid solutions with other carbonates from aragonite group: witherite (BaCO 3), cerussite (PbCO 3), strontianite (SrCO 3) and smithsonite …
Aragonite, CaCO 3, is classified as a Aragonite Group Carbonate. A calcium carbonate mineral with a formula unit identical to — and thus a polymorph of — calcite, aragonite …
A pair of doubly terminated, translucent and lustrous, hexagonal aragonite crystals from the Type Locality in Spain. The body is a nice lavender color, which grades to a light gray …
Aragonite is a carbonate mineral, one of the two common, naturally occurring polymorphs of calcium carbonate, CaCO3. The other polymorph is the mineral calcite. Aragonite's crystal lattice differs from that of …
aragonite, widespread mineral, the stable form of calcium carbonate (CaCO 3) at high pressures. It may be distinguished from calcite, the commoner form of calcium carbonate, by its greater hardness and …
In aragonite, triangular (CO 3) 2- groups are in layers perpendicular to the c-axis, as in calcite. Alternate layers, however, have their (CO 3) 2- groups pointing in …
