Aragonite and calcite with botryoidal side Chalcedony nodules It's possible they are actuallyLocale: Sidi Ayed, Fs Mekns Region, Morocco Approx dimensions: 2. 25 x 2 x 1. 5" Approx size: 185g 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 chemical
