Definition

Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

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

Etymology

From Latin conglomeratus, to roll together, i.e. from com together + glomerare to gather into a ball, from glomus (genitive glomeris) a ball

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

Formation

Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

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

All about Conglomerate and Eclogite Properties

Know all about Conglomerate and Eclogite properties here. All properties of rocks are important as they define the type of rock and its application. Conglomerate belongs to Sedimentary Rocks while Eclogite belongs to Metamorphic Rocks.Texture of Conglomerate is Clastic whereas that of Eclogite is Earthy. Conglomerate appears Shiny and Rounded and Eclogite appears Dull, Banded and Foilated. The luster of Conglomerate is dull while that of Eclogite is subvitreous to dull. Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors whereas Eclogite is available in black, brown, green, grey, pink, white colors.
