[Ebeam]: Present analyses of enstatite from the same ~5 μm grain that waspresent in the bulb area of the track. All enstatite analyses show Cr higher than Fe. Also, I observed 20 - 50 nm round Ni-free Fe inclusions (metal?) around or possibly in the enstatite grains. At first I thought these grains were present in the enstatite as inclusions but now I'm not so sure and need to go back sometime and check. Also, a few slivers in the interior of this 5 μm grain appear to be forsterite but edx analyses of these grains are non-stoichiometric (forolivine). Lots of the usual melt with metal beads is also present in the bulb area and also as a rim on the 5 μm grain which the enstatite analyses are from. Nice vesicles in SiO2-rich glass with hollow Fe sulfides plating their interiors are visible as are solid Fe-Ni metal grains with Fe sulphide rims.
