Definition
Hornblendite is a type of igneous plutonic rock consisting mainly of amphibole hornblende and is a type of Amphibolite rock
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Hornblendite 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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

All about Hornblendite and Suevite Properties
Know all about Hornblendite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Hornblendite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Hornblendite is Banded, Foliated, Massive whereas that of Suevite is Earthy. Hornblendite appears Foliated and Suevite appears Banded. The luster of Hornblendite is vitreous to dull while that of Suevite is earthy. Hornblendite is available in black, brown, green, grey colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Hornblendite are cemetery markers, commemorative tablets, creating artwork and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
