Definition

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

Diamictite is a sedimentary rock that consists of non-sorted to poorly sorted terrigenous sediment containing particles that range in size from clay to boulders, suspended in a matrix of mudstone or sandstone

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.

Diamictite is unevenly sorted terrigenous, non-calcareous sedimentary rock which forms due to weathering of mudstone and sandstone.

All about Amphibolite and Diamictite Properties

Know all about Amphibolite and Diamictite properties here. All properties of rocks are important as they define the type of rock and its application. Amphibolite belongs to Metamorphic Rocks while Diamictite belongs to Sedimentary Rocks.Texture of Amphibolite is Banded, Foliated, Massive whereas that of Diamictite is Clastic. Amphibolite appears Foliated and Diamictite appears Banded. The luster of Amphibolite is vitreous to dull while that of Diamictite is grainy, pearly and vitreous. Amphibolite is available in black, brown, green, grey colors whereas Diamictite is available in brown, buff colors. The commercial uses of Amphibolite are cemetery markers, commemorative tablets, creating artwork and that of Diamictite are commemorative tablets, creating artwork, production of lime.
