Monzonite and Amphibolite

Monzonite

Amphibolite

Definition

Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation

Monzonite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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 Monzonite and Amphibolite Properties

Know all about Monzonite and Amphibolite properties here. All properties of rocks are important as they define the type of rock and its application. Monzonite belongs to Igneous Rocks while Amphibolite belongs to Metamorphic Rocks.Texture of Monzonite is Phaneritic whereas that of Amphibolite is Banded, Foliated, Massive. Monzonite appears Shiny and Amphibolite appears Foliated. The luster of Monzonite is subvitreous to dull while that of Amphibolite is vitreous to dull. Monzonite is available in black, brown, light to dark grey, white colors whereas Amphibolite is available in black, brown, green, grey colors. The commercial uses of Monzonite are creating artwork and that of Amphibolite are cemetery markers, commemorative tablets, creating artwork.
