maps12238-sup-0001-FigS1.docWord document998KFig. S1: X-ray maps of Mg, Fe, Ca, Mn, Al, Cr, Ni, and Ti in the rounded olivine grain of the Kaba meteorite. Ca and Al concentrate in the core of the grain and are almost undetectable in the rim, but the variations of the other concentrations cannot be well evaluated because of low intensities of their signals. The matrix enclosing the olivine grain consists mainly of Ca-Al-rich region.
maps12238-sup-0002-FigS2.docWord document238KFig. S2: X-ray mapping of Mg, Fe, Ca, Mn, Al, Cr, Ni, and Ti in the porphyritic olivine grains in chondrule (B-2 area) reveals that the olivine grain is surrounded by mesostasis phases consisting of Ca-Al-rich material and has a Ca-Al-rich region in the core, consistent with CL image. The concentrations of Ca and Al seem to increase slightly toward the rim from the center of the grain.
maps12238-sup-0003-FigS3.docWord document268KFig. S3: X-ray mapping of Mg, Fe, Ca, Mn, Al, Cr, Ni, and Ti indicates lower amounts of Ca and Al in the rim than those in core of the coarse olivine grain embedded in matrix (B-4 area).
