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

Nepheline-Basanite, Analcite-Basanite and Leucite-Basanite
Features
Clasts are smooth to touch, Is one of the oldest rock, Matrix variable
Clasts are smooth to touch, Easily splits into thin plates, Has High structural resistance against erosion and climate, Used as a touchstone
Archaeological Significance
Formation
Conglomerate forms where sediments consisting mainly of pebble and cobble-size clasts at least two millimeters in diameter starts accumulating.
Basanite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

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