Fig. 3:  SNC METEORITES HAVE SAME PARENT BODY  Meteorites have an oxygen isotope ratio that is unique to their parent body or specific meteorite type. This chart shows that all of the SNC meteorites have the same unique oxygen isotope ratio, which means that all of the SNC meteorites are from the same parent body. The chart also illustrates how each meteorite group has an oxygen isotope ratio that is completely unique and separate from other meteorite groups.
