Gabbro is an intrusive igneous rock, meaning it is made of magma that solidifies inside of Earth's crust.  It contains many of the minerals we have already learned about: pyroxene, plagioclase, amphibole, and olivine.  Gabbro is coarse grained and porphyritic, meaning the size of the crystals vary.
