| 説明 | Overturned shales in the Mississippian of West Virginia, USA.The rocks shown here are overturned beds of the Hinton or Bluefield Formation (Upper Mississippian). Stratigraphic up is to the left (north). Rocks are dipping ~50° to the south. The rocks are mixed siliciclastics, dominated by mudshales. Minor lithologies include reddish-brown micaceous siltstone, sandstone, and fossiliferous limestone (bivalve crinkle bed with preserved shells). A float piece was observed having compacted ripple marks and bioturbation. Multiple horizons of halite salt casts in reddish and greenish-gray mudshale are also present.Stratigraphy: Hinton or Bluefield Formation, Upper Mississippian.Locality: roadcut through Divide Ridge on the northern side of Rt. 460, between Oakvale and Kellysville, southeastern Mercer County, far-southern West Virginia, USA (37º 20' 41.53" North latitude, 80º 56' 16.71" West longitude) |
