WE PRESENT THIS PIECE WITH A MIXTURE OF MINERALS. IN THIS PIECE WE CAN SEE FLUORITE AS THE MAIN MINERAL, ABOVE A CREST OF BARITE AND IN THE LOWER PART CHALCOPIRITE. ALSO IN THE CENTRAL PART THERE ARE SOME BLACK SPECKS WHICH ARE CRYSTALIZED PETROLEUM.
Fluorite is a group III mineral (halides) that according to the Strunz classification, formed the elements calcium and fluorine.
Its structure belongs to the cubic system, and it appears with a cubic, octahedral, and rhombododecahedral habit.
Fluorite has physical thermoluminescence and fluorescence properties.
In industry, it is mainly used in iron and steel metallurgy. It is used as a source of fluorine and hydrofluoric acid, also in the glazing of ceramics and in the manufacture of optical glasses.
The beauty of the specimens makes it a mineral much appreciated by museums and private collectors.
