In 2008, surface waters in the Canada Basin of the Arctic Ocean were found to be undersaturated with respect to aragonite. This is associated with recent extensive melting of sea ice in this region, as well as elevated sea surface temperature and atmospheric CO2 concentrations. We have estimated the relative contribution of each of …

On the other hand, patients who used the aragonite toothpaste were characterized by a lower level of calculus accumulation. This result indicates that cuttlebone‐derived aragonite toothpaste removes calculus. This is probably related to the unique hardness and specific surface area of the cuttlefish bone powder abrasives (North et al., 2017 ...

Aragonite is an important CaCO3 polymorph in carbonate sediments, forming both inorganically as early marine cement and biogenically as a skeletal phase. Ca 2 + exists in orthorhombic (ninefold) coordination in the aragonite lattice, allowing aragonite to accept larger cations such as Ba 2 + and Sr 2 +. Aragonite is more soluble than calcite ...

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".

You are indeed correct, Aragonite is a carbonate mineral, a polymorph of calcite. Calcite in turn is the most stable polymorph of Calcium carbonate (CaCO3) aragonite will turn to calcite when heated to 400-470°C (750-880°F). Vaterite is the other polymorph but converts to Calcite when heated to around 60°C (140°F).
