Marble and Amphibolite
Definition
Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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.

All about Marble and Amphibolite Properties
Know all about Marble and Amphibolite properties here. All properties of rocks are important as they define the type of rock and its application. Marble and Amphibolite belong to Metamorphic Rocks.Texture of Marble is Granular whereas that of Amphibolite is Banded, Foliated, Massive. Marble appears Veined and Shiny and Amphibolite appears Foliated. The luster of Marble is dull to pearly to subvitreous while that of Amphibolite is vitreous to dull. Marble is available in black, blue, brown, grey, pink, white colors whereas Amphibolite is available in black, brown, green, grey colors. The commercial uses of Marble and Amphibolite are cemetery markers, commemorative tablets, creating artwork, curling, laboratory bench tops, paper industry, tombstones, used in aquariums, whiting material in toothpaste, paint and paper.
