Stroud [TEM]: Crystalline silicate. The diffraction patterns (three different zones recorded) suggest a monoclinic phase with lattice parameters close to enstatite, but some reflections from enstatite are missing. It could be overcoated with some melted aerogel. (Mg+Fe)/Si is 2/3. Same particle was rich in C according to Cody and Alexander.
