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.

Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

All about Amphibolite and Turbidite Properties

Know all about Amphibolite and Turbidite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Turbidite belongs to Sedimentary Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Turbidite is Mud-rich, Sandy. Amphibolite appears Foliated and Turbidite appears Dull and Banded. The luster of Amphibolite is vitreous to dull while that of Turbidite is metallic. Amphibolite is available in black, brown, green, grey colors whereas Turbidite is available in black, brown, green, grey, pink colors. The commercial uses of Amphibolite and Turbidite are cemetery markers, commemorative tablets, creating artwork.
