WHAT IS THE BASALT ?

BASALT: a type of very hard, dark, dense rock, igneous in origin, composed of augite or hornblende and containing titaniferous magnetic iron and crystals of feldspar. It often lies in columnar strata, as at the Giant’s Causeway in Ireland and Fingal’s Cave in the Hebrides. It is greenish- or brownish-black and much like lava in appearance. It is also abundant in Egypt and Greece.
