Aragonito Blanco (Bulboso)
Aragonito is a mineral with formula CaCO₃, in the Carbonatos group. This specimen comes from Macael, Almería, Andalucía, España and joined the Terrium collection in 2005.
Description
Bulbous and stalactitic crystals. Shows dual fluorescence, possibly due to the possible presence of magnesium in the crown zone.
About Aragonito
It seems simple, but it is not. Its white, bulbous form recalls inert concretions, yet it grew drop by drop from the roof of a cavity, forming cottony-looking stalactites. It is aragonite, a polymorph of calcite, less stable but more distinctive.
About the locality
From Macael, known for its white marble, where stalactitic aragonites also form in fissures associated with hydrothermal processes.
