Summary
[edit]DescriptionMinor thrust fault in limestone-shale (Upper Ordovician; Maysville West upper roadcut, Kentucky, USA) 4.jpg |
English: Minor thrust fault developed in Ordovician interbedded limestones & shales in 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. Most of the limestones are event beds (= tempestites), deposited during ancient storms. The gash extending from upper right to lower left is a minor thrust fault. It is developed in the Bellevue Limestone and Fairview Formation. The fault acted as a conduit for groundwater, which dissolved out a small cave along the strike of the fault (see: www.flickr.com/photos/jsjgeology/31949022868). Thrust faults are low-angle reverse faults - they form by compressional stress. Thrust faults involve the hanging wall moving upward and the footwall moving downward. Stratigraphy: Bellevue Limestone over Fairview Formation, Maysvillian Stage, middle Cincinnatian Series, Upper Ordovician Locality: Maysville West upper cut - roadcut on the southeastern 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’ 04.23" North latitude, 83° 48' 07.08" West longitude) |
