    Granite Granite is an igneous rock which has cooled slowly, allowingdistinctive crystal patterns to form. These crystals are clearly visibleto the naked eye. Most granites consist of three minerals which canbe easily distinguished. Basalt Basalt is a common extrusive igneous rock formed from the rapidcooling of basaltic lava exposed at or very near the surface of aplanet or moon.

     · formation of granite. Probably the most widely-accepted idea (at least at the moment) is that granite magma originated from a mechanism called partial melting, in which rocks of a very different composition melt in stages and the initial magma is enriched in the minerals that melt first. But where that happens – whether in the mantle or in the lower lithosphere – remains unclear.
