[TEM]: Mostly aerogel. Some large grains. Relatively large grains are: Al-Zr-O material (amorphous) Si-O phase (crystalline), and Si-Ca-Mg-Al-O material (amorphous), and Ti-O phase (crystalline), roughly in the order of abundance. Minor constituents are: K-Al-Si-O phase (crystalline), Ca-O phase (crystalline), and (3) Fe-O phase (crystalline). EDS analyses and SAED patterns of K-rich grain suggest that it may be related to K-feldspar. Ca rich grain might be carbonate.
