Amphibolite and Migmatite

1 Definition
1.1 Definition
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase
Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components

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.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

All about Amphibolite and Migmatite Properties

Know all about Amphibolite and Migmatite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite and Migmatite belong to Metamorphic Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Migmatite is Foliated. Amphibolite appears Foliated and Migmatite appears Dull, Banded and Foilated. The luster of Amphibolite is vitreous to dull while that of Migmatite is dull to pearly to subvitreous. Amphibolite is available in black, brown, green, grey colors whereas Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Migmatite are cemetery markers, jewelry, tombstones, used to manufracture paperweights and bookends.
