| Text Description: | A variable-thickness, medium-grained, light-beige tephra layer was collected 103 cm below the top of a 2 m coal unit. A very platy, 22-cm thick coal with barely coalified plant fragments directly overlies FC14. About 20 cm of carbonaceous shale underlies the tephra-layer with a sharp boundary. The grain mount contains mostly fragments of stretched glass and bubble-wall shards. The glass is generally clear and quite unaltered, although the edges may have some minor alteration. Uncommon glass shards are black, and there are a few brown colored glass fragments. The glass is mixed with orange-brown organic material in nearly equal amount. About 1-2% of plagioclase laths and opaques. |
