Definition

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

Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Etymology

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

From English clay and stone as the rock contains more amount of clay

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.

Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
