Definition
Basanite is a black basaltic rock which mainly contains plagioclase, augite, olivine and nepheline and is formerly used as a touchstone
Conglomerate is a sedimentary rock which forms from rounded gravel and boulder sized clasts which are cemented together in a matrix

Archaeological Significance
Formation
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.

All about Basanite and Conglomerate Properties
Know all about Basanite and Conglomerate properties here. All properties of rocks are important as they define the type of rock and its application. Basanite belongs to Igneous Rocks while Conglomerate belongs to Sedimentary Rocks.Texture of Basanite is Aphanitic to Porphyritic whereas that of Conglomerate is Clastic. Basanite appears Glassy or Pearly and Conglomerate appears Shiny and Rounded. The luster of Basanite is waxy and dull while that of Conglomerate is dull. Basanite is available in black, brown, green, grey, red, white colors whereas Conglomerate is available in beige, black, brown, buff, light to dark grey, orange, rust, white, yellow 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 Conglomerate are cemetery markers, in aquifers, tombstones.
