Aragonite and calcite Ferruginous quartz the pair is nearly completelyLocale: Sidi Ayed, Fs Mekns Region, Morocco Approx dimensions: 3. 75 x 2. 5 x 2 Approx size: 700g (1. 5 lb) Calcite and aragonite are polymorphs of one another, meaning that the same chemical composition (calcium carbonate) has crystallized into different crystal structures (trigonal and orthorhombic, respectively). Calcite and aragonite often grow together, and the two minerals are also frequent paramorphs of one anothera pseudomorph of the same
