Toward sustainable syntheses of Ca-based MOFs
O) was initially prepared from commercial CaCO 3 (calcite polymorph) by simply adding the metal carbonate to an aqueous solution of squaric acid and stirring for 24 hours at room temperature. An immediate colour change of the solution from colourless to purple and effervescence from carbon dioxide production signified reaction had occurred.

The role of Mg2+ in inhibiting CaCO3 precipitation from seawater
With a Mg:Ca ratio of 5.2 in surface seawater, Mg 2+ is incorporated in calcite, increasing its surface energy and thus raising the supersaturation state needed to form stable CaCO 3 nuclei that can sustain precipitation. Particles in seawater may act as seeds and induce the precipitation of CaCO 3.

Aragonite – Virtual Museum of Molecules and Minerals
The iridescent surface of pearl and mother-of-pearl is a layer of Aragonite secreted by mollusks and related invertebrates. Aragonite is less stable and less common than calcite. Aragonite can be found as hot spring deposits when water, releasing calcium upon reaching the air, forms mounds and thick crusts around the spring ("travertine").

Halite | Common Minerals
Since it forms primarily from evaporation, halite normally is found with other evaporation-associated minerals such as calcite, gypsum, anhydrite, and sylvite. Sylvite, although rare, is poisonous - so it is a good idea to use your finger to test an unknown sample's taste, rather than directly licking the sample.

What is Calcite | Natural History Museum of Utah
Calcite dissolves easily in weak acids including vinegar and gives off bubbles of CO 2. A very special characteristic of transparent calcite is birefringence (double refraction). A line viewed through the crystal will appear double. One characteristic that makes calcite so interesting to collectors is the variety of crystal habits.
