Archaeological Significance
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.

Learn more about Properties of Amphibolite
What is Amphibolite? In this section, we will learn more about properties of Amphibolite i.e. physical and thermal properties. Physical properties of Amphibolite include Color, Streak, Hardness, Structure, Cleavage, Fracture, Luster, Specific Gravity etc. The strength of Amphibolite is 90.00 N/mm2. Streak of Amphibolite is white to grey while its cleavage is . Luster of Amphibolite is vitreous to dull and its fracture is irregular to conchoidal. Amphibolite is opaque in nature.
