Summary
[edit]DescriptionTruncated bedding in sandstone (Vinton Member, Logan Formation, Lower Mississippian; Mohawk Dam emergency spillway, western Coshocton County, Ohio, USA) 1 (27164004851).jpg |
Sandstone with truncated bedding in the Mississippian of Ohio, USA. (cross-section view) The Vinton Member is the uppermost of four stratigraphic units in the Mississippian-aged, siliciclastics-dominated Logan Formation of eastern Ohio. Ascending from the base, they are the Berne Conglomerate Member, the Byer Sandstone Member, the Allensville Member, and the Vinton Member. The Vinton is dominated by siltstones but sandstones and shales are also present. The outcrop shown above shows relatively fine-grained quartzose sandstone with truncated bedding. The tilted beds in the lower half of the photo are crossbeds, which form in a one-directional current by wind or water - in this case, water. The Vinton represents relatively shallow marine facies. Stratigraphy: Vinton Member, upper Logan Formation, Osagean Stage, upper Lower Mississippian Locality: Mohawk Dam emergency spillway, northwest of the town of Nellie, western Coshocton County, eastern Ohio, USA (vicinity of 40º 21' 26.42" North latitude, 82º 04' 57.97" West longitude) |
