QUÉ SIGNIFICA ECLOGITE EN INGLÉS
Eclogita
Eclogite / ɛklədʒaɪt / es una roca metamórfica máfica; "Eclogita máfica" es redundante. La eclogita es de especial interés por al menos dos razones. Primero, se forma a presiones mayores que las típicas de la corteza de la Tierra. En segundo lugar, siendo una roca inusualmente densa, la eclogita puede jugar un papel importante en conducir la convección dentro de la tierra sólida. La roca fresca puede ser sorprendente en apariencia, con rojo a rosa granate en una matriz verde de piroxeno rico en sodio. Los minerales accesorios incluyen kyanita, rutilo, cuarzo, lawsonita, coesita, anfibola, phengite, paragonita, zoisita, dolomita, corindón y, raramente, diamante. La plagioclasa no es estable en la eclogita.
definición de eclogite en el diccionario inglés
La definición de eclogite en el diccionario es una rara roca básica de grano grueso que consta principalmente de granate y piroxeno. Cuarzo, feldespato, etc., también pueden estar presentes. Se cree que se origina por metamorfismo o cristalización ígnea a una presión extremadamente alta.

Eclogite is appreciably denser than garnet peridotite and should therefore occur
deeper in a gravitationally stable mantle. I have suggested that the Lehmann
