Calcite and aragonite carry the same formula, CaCO₃, and assemble it differently inside. That structural difference is why aragonite is denser and slightly harder than calcite despite being chemically identical.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eThis slice is the aragonite side of that split. It formed in karst cavities in Cambrian limestone at Ighoud, western Morocco, where carbonate-carrying water moved through rock and left mineral behind in layers.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eCut across the growth direction, the banding becomes readable.
