Fairborn Ohio drill core high resolution total gamma (API) log of Fort Ancient and Clarksville members of the Waynesville Formation

This high-resolution total gamma (API) dataset from the Fort Ancient and Clarksville members of the Waynesville Formation (Late Ordovician, Katian) shows a shift from obliquity and precession dominance to increased influence from short eccentricity. Data were collected using a Core Labs gamma ray spectrometer using a version of the software "Gamma" which allows for ultra slow runs (available from Core Labs).
