Conglomerate and Amphibolite


Definition

Definition
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase   
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Formation

Formation
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.   
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Amphibolite and Conglomerate Properties

Know all about Amphibolite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Conglomerate is Clastic. Amphibolite appears Foliated and Conglomerate appears Shiny and Rounded. The luster of Amphibolite is vitreous to dull while that of Conglomerate is dull. Amphibolite is available in black, brown, green, grey colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Conglomerate are cemetery markers, in aquifers, tombstones.
