Yeso
Yeso is a mineral with formula CaSO₄·2H₂O, in the Sulfatos group. This specimen comes from Túnel José Maestre, Portmán, Murcia, Región de Murcia, España and joined the Terrium collection in 2016.
Description
Pale yellow acicular crystals, very fine and delicate, arranged radially on a ferruginous matrix. The contrast between the warm hue of the crystals and the dark base emphasises the sculptural character of the specimen.
History of this specimen
It was the specimen that changed the way Pedro and I recorded and edited the minerals we had, the one with which we added rocky and drone-like sounds.
About Yeso
Gypsum is a very common hydrated sulphate, but the well-formed acicular specimens from Portmán are highly regarded for their transparency and radial arrangement.
About the locality
Historic extraction at Túnel José Maestre ceased decades ago; the workings are now collapsed or inaccessible, making older specimens increasingly difficult to find.
