Exposures in Lawrence, Martin, and Orange counties, Indiana (Fig. 1), show abrupt lateral lithologic changes in the Reelsville (lower Chester) limestone. The overlying Elwren formation appears to rest unconformably on the Reelsville in these sections, but a significant unconformity can not be demonstrated because: (1) sediments above and below the Reelsville are similar and do not show evidence of a break in deposition where the Reelsville limestone is absent, and (2) Reelsville fossils are found locally in clastic beds that are lateral equivalents of the Reelsville limestone. Fossils are exceedingly rare in the clastic formations of the lower...
