| 説明 | Overturned shales in the Mississippian of West Virginia, USA. (looking west) (2016)The rocks shown here are overturned beds of the Hinton or Bluefield Formation (Upper Mississippian). Stratigraphic up is to the right (north). Rocks are dipping ~50° to the south. The beds are mostly reddish and greenish-gray mudshales with some resistant siltstone & sandstone interbeds. Some of the sandstones have shale rip-up clasts. Well-defined burrows (trace fossils) can be found in some of the hard mudshales and sandstones. Observed body fossil occurrences here include bivalve pavements (see: www.flickr.com/photos/jsjgeology/15042997768) and poorly defined, carbonized plant fossil fragments in the shales. Some loose shale and sandstone samples have fault slickenlines.Stratigraphy: Hinton or Bluefield Formation, Upper Mississippian.Locality: Oakvale School Outcrop - roadcut through Divide Ridge on the western side of Rt. 112, across from Oakvale School, immediately south of Rt. 460, far-southeastern Mercer County, far-southern West Virginia, USA (37º 20' 22.84" North latitude, 80º 57' 20.49" West longitude) |
