Definition
Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar,biotite, hornblende, and pyroxene
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

Archaeological Significance
Formation
Diorite is a coarse-grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the Earth’s surface and cools down in the Earth’s crust.
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 Diorite and Suevite Properties
Know all about Diorite and Suevite properties here. All properties of rocks are important as they define the type of rock and its application. Diorite belongs to Igneous Rocks while Suevite belongs to Metamorphic Rocks.Texture of Diorite is Phaneritic whereas that of Suevite is Earthy. Diorite appears Shiny and Suevite appears Banded. The luster of Diorite is shiny while that of Suevite is earthy. Diorite is available in black, brown, light to dark grey, white colors whereas Suevite is available in black, brown, green, grey, pink colors. The commercial uses of Diorite are creating artwork, curling and that of Suevite are as a feed additive for livestock, gemstone, metallurgical flux, source of magnesia (mgo).
