Mineralogy and apparent grain sizes Terminal particle: TP was removed from keystone prior to receiving it at Univ. of Washington. Fragment 2 100% compressed aerogel. No minerals observed in microtomed sections. Fragment 3 (>5 um) Fo70-80, olivine structure confirmed by electron diffraction Minor Mg+Al silicate glass Trace 50 nm FeZn sulfides Significant compressed aerogel rim Fragment 8 (>7 um) Fo69-81 with minor silicate glass (minor Na, Al and Mg) Olivine structure confirmed by electron diffraction Other minor/trace minerals observed: Isolated 2 um grain of amorphous SiO2. 75 nm Mg+Al+Ti-bearing chromite inclusion in olivine.
