| 説明 | Limestones & shales in the Ordovician of Kentucky, USA.This outcrop is in the famous Cincinnatian Series of the tristate area of Ohio-Kentucky-Indiana. Rocks in the Cincinnatian were deposited in relatively shallow marine facies during the Late Ordovician. The Cincinnatian succession is mostly interbedded limestones and shales - all richly fossiliferous. Most of the limestones are event beds (= tempestites), deposited during ancient storms.The lower wall of this northern Kentucky roadcut is the Fairview Formation, which is about 50-50 interbedded fossiliferous limestone and shale. The middle and upper walls are the limestone-dominated Bellevue Limestone. The Fairview-Bellevue is a part of a coarsening-upward and shallowing-upward succession.Stratigraphy: Fairview Formation, lower Maysvillian Stage, middle Cincinnatian Series, Upper OrdovicianLocality: Maysville West upper cut - roadcut on the northwestern side of Rt. 62/Rt. 68, just south of bridge over Lawrence Creek & south of the Harsha Bridge over the Ohio River, northern Kentucky, USA (~vicinity of 38° 40’ 07.15" North latitude, 83° 48' 05.57" West longitude) |
