STXM Analysis Summary 5 particles in the keystone, obvious in STXM images. One particle is a cluster containing a <1 µm corundum grain (verified by Al K-edge XANES) and two pyroxene grains (Mg K-edge XANES). The rest are of glassy morphology containing aluminum and sodium present at percent levels. Ce not detected. Keystone was too thick for reliable iron measurement.
