    Aug 22, 2019 · 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 calcite, resulting in a different crystal shape, an orthorhombic system with acicular crystals.

  • Aragonite: The mineral aragonite information and pictures

    A particularly interesting formation of Aragonite is as a deposition product of hot, mineral-rich springs. The water releases calcium upon emerging from the spring, and forms growing mounds and thick crusts around the springs. When these are banded, they may be carved and given trade names such as "Onyx Marble", and "California Onyx".
