Tieschitz is interesting in thin section. In our sample, large and small chondrules are set apart by opaque matrix. Radial pyroxene and cryptocrystalline chondrules display aqueous alteration. One large chondrule contains several relict grains. We see chondrules that appear to be radial olivine darkened with fine included particles, probably amphiboles or other alteration products, and by rust stains. There is one chondrule containing finely dendritic olivine.
