Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle

Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

All about Basanite and Peridotite Properties
Know all about Basanite and Peridotite properties here. All properties of rocks are important as they define the type of rock and its application. Basanite and Peridotite belong to Igneous Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Peridotite is Phaneritic. Basanite appears Glassy or Pearly and Peridotite appears Rough and Shiny. The luster of Basanite is waxy and dull while that of Peridotite is shiny. Basanite is available in black, brown, green, grey, red, white colors whereas Peridotite is available in dark greenish - grey colors. The commercial uses of Basanite are as a touchstone, creating artwork, gemstone, in fire-starting tools, manufacture of tools, metallurgical flux, jewelry, to ignite fire, used in flintlock firearms and that of Peridotite are creating artwork, gemstone, jewelry, source of chromite, platinum, nickel and garnet, source of diamonds.
