Abstract

This Ordovician unit, across the Indiana-Kentucky boundary, is lens-shaped, essentially calcitic dolomite thinly interbedded with fossiliferous limestone and shale. A laterally persistent clay shale in the lower half is an isochronous marker; a zone of corals lies near the base, a coral-stromatoporoid zone near the top. Quiet, shallow lagoonal deposition is suggested, random orientation of coral coloniesdenoting outer turbulence. Centripetal decrease in calcite-dolomite ratio reflects greater salinity during middle Saluda deposition; dolomite apparently was a primary precipitate, or formed early by recrystallization of magnesian calcite or by reaction of mud with penesaline water. There are scattered signs of intermittent subaerial exposure by evaporation; normalcy returned by subsidence greater than that with which coral growth could keep pace.
