Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, CaCO3 (the other forms being the minerals calcite & vaterite). It is formed by biological & physical processes, including precipitation from marine & freshwater environments. The crystal lattice of aragonite differs from that of calcite, resulting in a different crystal shape, an orthorhombic crystal system with acicular crystal. Repeated twinning results in pseudo-hexagonal forms. Aragonite may be columnar or fibrous, occasionally in branching helictitic forms called flos-ferri ("flowers of iron") from their association with the ores at the Carinthian iron mines. Physical properties Aragonite is not the thermodynamically stable phase of calcium carbonate at any pressure below about 3,000 bars (300,000 kPa) at any temperature.[23] Aragonite nonetheless frequently forms in near-surface environments at ambient temperatures. The difference in stability between aragonite & calcite, as measured by the Gibbs free energy of formation, is small, & effects of grain size & impurities can be important. The formation of aragonite at temperatures & pressures where calcite should be the stable polymorph may be an example of Ostwald's step rule, where a less stable phase is the first to form.[24] The presence of magnesium ions may inhibit calcite formation in favor of aragonite. ATTRIBUTES Aragonite is a reliable earth-healer & grounding stone. Attuned to the Earth Goddess, it encourages conservation & recycling. This stone transforms geopathic stress & clears blocked ley lines even at a distance. With its ability to center & ground physical energies, it is useful in times of stress. Aragonite stabilizes the base & earth chakras, deepening connection with the earth. Hall, Judy. The Crystal Bible (The Crystal Bible Series) (pp. 69-70). Penguin Publishing Group. Kindle Edition.
