| Text Description: |
An 8-10 cm orange-black, coarse-grained sandy layer was sampled 17 cm from the top in a 190 cm coal bed. The layer appears somewhat coarser at the base. The overlying 17 cm of the coal is hard and splintery, but turns into dark carbonaceous shale 4 cm above the layer, which has sharp boundaries with the enclosing coal/carbonaceous shale. The sandy layer pinches and swells and is locally carbonaceous. Below the MC1 is about 50 cm of hard splintery coal, some of which is fusinite. An 8 cm shale layer occurs 10 cm from the base of the coal. This layer is also swelling and pinching. The base of the coal has a sharp boundary with the siltstone below. About 40% subrounded to rounded, zoned and twinned plagioclase, 7-10% very altered, rounded volcanic rock fragments, and 5-10% subrounded quartz. Trace epidote, K-spar altered to sericite, chlorite, sphene, opaques, clay fragment~, and organic material. |
