Aragonite: Mineral information | Rock & Gem Magazine

2019-7-11 · Aragonite is a wonderful collector mineral because it is common enough to be found in quantity. It develops in a variety of attractive crystals. Some are long, tapered beauties that approach needle-like form. Such superb slender aragonites were found in Podrecony, Slovakia. These crystals measured as much as 6 inches long and are snow-white ...

Aragonite CaCO 3 (Pmcn and Z = 4) is a commen calcium carbonate mineral in pelagic marine sediments. It shows a greater stability over its homomorphic polymorph, calcite (R-3 c and Z = 6), above 0.3–2 GPa [17,18]. Aragonite had long been considered a stable CaCO 3-polymorph in the earth''s interior from megapascals regimes to the lower ...
