The bulk trace element composition (Ca, Ti, Cr, Mn, Ni Cu, Zn, Ge, Se, Rb, Sr, Y, Zr, Mo) of eighty-three Antarctic micrometeorites was nondestructively analyzed using synchrotron radiation X-ray fluorescence analysis (SR-XRF), and these elements were characterized in terms of their abundance ratio relative to Murchison matrix composition. The relationship between heating history and chemical composition is also examined. We found a complementary relationship among I-type, S-type and unmelted AMMs in the micrometeorites' elemental abundance, which is consistent with the hypothesis that I-type and S-type spherules were separated from chondritic meteoroids.
