Definition

Eclogite is an extreme metamorphic rock, formed by regional metamorphism of basalt rock under very high pressure and temperature

A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles

Etymology

From French, Greek eklogē selection with reference to the selective content of the rock + -ite1

From Medieval Latin turbiditas, from Latin turbidus (turbid). Turbidity current is from 1939

Formation

Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
