QUÉ SIGNIFICA OLIVINE EN INGLÉS
Olivine
El olivino mineral es un silicato de magnesio y hierro con la fórmula 2SiO4. Es un mineral común en la subsuperficie de la Tierra, pero se cuece rápidamente en la superficie. La proporción de magnesio y hierro varía entre los dos extremos de la serie de soluciones sólidas: forsterita y fayalita. Las composiciones de olivina se expresan comúnmente como porcentajes molares de forsterita y fayalita. La forsterita tiene una temperatura de fusión inusualmente alta a presión atmosférica, casi 1900 ° C, pero la temperatura de fusión de la fayalita es mucho menor. La temperatura de fusión varía suavemente entre los dos extremos, al igual que otras propiedades. Olivina incorpora sólo pequeñas cantidades de elementos distintos de oxígeno, silicio, magnesio y hierro. Manganeso y níquel comúnmente son los elementos adicionales presentes en concentraciones más altas. Olivine da su nombre al grupo de minerales con una estructura relacionada que incluye tefroita, monticelita y kirschsteinita. La estructura cristalina de Olivine incorpora aspectos de la red P Bravais ortorrómbica, que surgen de cada unidad de sílice unida por cationes divalentes metálicos con cada oxígeno en SiO4 unido a 3 iones metálicos.
