Calcita
Calcita is a mineral with formula CaCO₃, in the Carbonatos group. This specimen comes from Mina La Araña, Málaga-Este, Málaga, Andalucía, España and joined the Terrium collection in 2025.
Description
Honey-coloured calcite aggregate with a "Transylvania Castle" form or a lateral "cresta montis" ridge. Very intense bluish-white fluorescence.
About Calcita
Calcite is a calcium carbonate which in this specimen shows a honey-yellow tone, probably linked to micro-inclusions or growth defects. It shows an exceptional luminescent response: under long-wave UV light it emits a very strong bluish-white fluorescence, a phenomenon common in specimens from karst environments with specific mineral activators.
About the locality
The La Araña quarries, on the eastern coast of Málaga, lie on intensely fractured Triassic limestones. The designation of the area as a Bien de Interés Cultural (BIC) in 2013, due to its archaeological finds, has completely restricted mineral collecting.
