Geological & Scientific Details
Aragonite is classified as a carbonate minerals mineral which typically crystallizes in the orthorhombic system. Its chemical formula is Ca CO3. Common crystal habits include commonly dendritic or pseudo-hexagonal; can also be acicular, tabular, prismatic, coral-like.
Key Geological Properties:
