Crisocola

Características generales


Datos generales


Fórmula: Cu2-xAlx(H2-xSi2O5)(OH)4·nH2O
Sistema de cristalización: Monoclínico
Lustre: Vítreo plomizo
Color: Verde a azul, a veces pardo
Dureza: 2,4
Rareza: común
Características distintivas: Lack of crystals, colour, fracture, low density and softness.
La crisocola es en gran parte una mezcla amorfa de varios silicatos de cobre y sílice hidratada, que contiene diversas impurezas como la alumina, óxidos de cobre y óxidos limoníticos; por este motivo el color del mineral típicamente azulado o verdoso puede oscurecerse hasta adquirir tonos pardos. Se presenta en concreciones compactas, alguna vez en masas criptocristalinas con estructura finamente radiada o globosa, o bien en cristales aciculares microscópicos, rómbicos o monoclínicos, a menudo asociados a azurita o malaquita.

Clasificación

Estado IMA: Válido. Descrito con antelación a 1959 (pre-IMA), se considera un mineral clásico o histórico (grandfathered)

Nickel-Strunz : 09.ED.20
  • 9: Silicatos
  • 09.E: Filosilicatos
  • 09.ED: Phyllosilicates with kaolinite layers

Dana 8th ed. : 74.3.2.1

Etimología:

Su nombre deriva de los términos griegos hrusos (oro) y kolla, cola, a causa de su semejanza con varios materiales utilizados en la antiguedad para soldar el oro.



Formación y ambiente

La crisocola es una mineral de formación secundaria, se forma en la parte superior de los yacimientos de cobre, la llamada zona de oxidación, por lo que es fácil encontrar la crisocola asociada a otros minerales del cobre como son la cuprita, azurita, malaquita y otros muchos minerales secundarios del cobre, como la limonita. Esta característica hizo que fuera usada por los mineros de la antigüedad como indicador en la superficie de yacimientos de cobre.
