Earth’s most abundant mineral, which lies deep down in the earth, was discovered in a 4.5 billion year old meteorite in Queensland, Australia.  Finding this mineral allowed scientists to characterize and rename it.  The mineral formally named silicate-perovskite was renamed bridgmanite.  Scientists Chi Ma and Oliver Tschauner performed tests for five years in order to characterize the mineral.  Some of these tests included synchrotron X-ray diffraction mapping and high-resolution scanning electron microscopy.  All of their hard work paid off when on June 2, 2014 the new mineral was approved by the International Mineralogical Association’s Commission on New Minerals, Nomenclature and Classification (CNMNC).
