Description

The Oglesby Syncline is a short, east-northeast-trending depression that could be considered a lobe of Willman and Payne's (1942) Granville Basin. It was mapped from borehole data on various Cambrian and Ordovician formations and shown as lying immediately west of what is now called the Peru Monocline. Newer maps, including those of Bristol and Buschbach (1973) and Kolata et al. (1983), do not indicate the Oglesby Syncline; accordingly, use of the name should be discontinued.
