CE ÎNSEAMNĂ ANDALUSITE ÎN ENGLEZĂ?
andaluzit
Andaluzitul este un mineral nesosilicat din aluminiu cu formula chimică Al2SiO5. Andaluzitul este trimorfic cu cyanite și sillimanite, fiind polimorful temperaturii medii la presiune joasă. La temperaturi și presiuni mai mari, andaluzitul se poate transforma în sillimanită. Astfel, ca și în celelalte polimorfe, andaluzitul ia un mineral indice aluminosilicat, furnizând indicii pentru adâncimea și presiunile implicate în producerea rocilor gazdă.
