Definition

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

Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

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.

Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
