#igneous_rock__igneousrock  rock formed by the solidification of molten magma
  supertype:  #rock__stone  material consisting of the aggregate of minerals like those making up the Earth's crust
  substance:  #sodalite
  subtype:  #andesite  a dark gray volcanic rock
  subtype:  #aplite  light-colored and fine-grained granitic rock consisting chiefly of quartz and feldspars
  subtype:  #groundmass  the matrix of fine-grained crystalline material in which larger crystals are embedded
  subtype:  #andosite  dark grayish extrusive rock
  subtype:  #batholith__batholite__pluton__plutonic_rock  large mass of intrusive igneous rock believed to have solidified deep within the earth
     subtype:  #granite.batholith  plutonic igneous rock having visibly crystalline texture
  subtype:  #diorite  a granular crystalline intrusive rock
  subtype:  #gabbro  one of a family of granular intrusive rocks
  subtype:  #pegmatite  a form of igneous rock consisting of extremely coarse granite resulting from the crystallization of magma rich in rare elements
  subtype:  #peridotite  a dark coarse-grained igneous rock consisting principally of olivine
     subtype:  #kimberlite  a rare type of peridotite that sometimes contains diamonds; found in South Africa and Siberia
  subtype:  #rhyolite  very acid volcanic rock
  subtype:  #volcanic_rock  extrusive igneous rock solidified near or on the surface of the Earth
     subtype:  #basalt  the commonest type of solidified lava; a dense dark gray fine-grained igneous rock composed chiefly of calcium-rich plagioclase feldspar and pyroxene
     subtype:  #volcanic_glass  a kind of natural glass produced when molten lava cools very rapidly
        subtype:  #obsidian  acid or granitic glass; usually dark, but transparent in thin pieces
        subtype:  #pitchstone  dark acid granitic glass
        subtype:  #tachylite  a basic or basalt glass
     subtype:  #lava  rock that in its molten form (as magma) issues from volcanos; lava is what magma is called when it reaches the surface
        subtype:  #pillow_lava  lava that hardened in rounded shapes suggestive of pillows; believed to result from underwater eruptions
     subtype:  #tuff__tufa  hard volcanic rock composed of compacted volcanic ash
  subtype:  #porphyry__porphyritic_rock__porphyriticrock  any igneous rock with crystals embedded in a finer groundmass of minerals
