| Text Description: | Sampled from a 150-cm thick, waterlaid, fine-grained tephra layer in siltstone and fine-grained sandstone. The sample is directly overlain by a 3-cm thick coal but may be contaminated by detrital sediments. About 40-50% of elongated glass fragments from stretched pumice shards. Some glass fragments are brown in color. About 5-7% hornblende, plagioclase, biotite, and quartz combined. Trace zircon and apatite. A few altered muscovite grains. |
