The data for "Highly Heterogeneous Parent Body of the Rare Andesitic Erg Chech 002 Meteorite Revealed by the Revisited Mn-Cr Isotopic Systematics"

This spreadsheet presents the original data for the elemental compositions of minerals in two EC 002 fragments. Table S1 shows the representative major elemental compositions of pyroxene xenocryst (from core to rim), groundmass pyroxene, groundmass feldspar, groundmass ilmenite, and groundmass chromite in fragment EC-1. Table S2 shows the representative major elemental compositions of pyroxene xenocryst (from core to rim), groundmass pyroxene, and groundmass feldspar in fragment EC-2.

The chemical compositions of minerals in EC-1 were analyzed with a JEOL JXA-8230 electron microprobe using a defocused beam of 25 kV and 10 nA at the Institute of Geochemistry, Chinese Academy of Sciences; while the chemical compositions of minerals in EC-2 were analyzed with a JEOL JXA-8530F Plus electron microprobe using a defocused beam of 15 kV and 10 nA at the University of Science and Technology of China.
