5 Formation
5.1 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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

All about Amphibolite and Granulite Properties

Know all about Amphibolite and Granulite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite and Granulite belong to Metamorphic Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Granulite is Granoblastic. Amphibolite appears Foliated and Granulite appears Veined or Pebbled. The luster of Amphibolite is vitreous to dull while that of Granulite is vitreous. Amphibolite and Granulite are available in black, brown, green, grey colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Granulite are curling, gemstone, laboratory bench tops, soil conditioner, tombstones.
