Basalt (UK: / b s l t,-l t /; US: / b s l t, b e s l t /) is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.More than 90% of all volcanic rock on Earth is basalt. Tetragonal crystal lattices result from stretching a cubic lattice along one of its lattice vectors, so that the cube becomes a rectangular prism with a square base ( a by a ) Its natural form is a mixture of several isotopes, three of which are unstable with long half-lives. e.g., phase transitions in quartz, cristobalite and leucite; structural views (cages, chains), etc. Finally, most lists of toxic gems on crystal healing websites include aluminum and a few other elements as toxic. The surface along which the lattice points are shared in twinned crystals is called a composition surface or twin plane. Feldspar; leucite, nepheline and nepheline syenite; fluorspar.
