The Salem Limestone and Associated Formations in South-Central Indiana

Abstract

This field conference was organized to promote a better understanding of the geology of the Salem limestone and associated formations and the physiography of the region in which these rocks are exposed. The conference has been limited to a tract which displays the characteristic lithologies and relationships of the Salem. Both the geologist and the layman have recognized the excellence of the Salem as a dimension stone for more than a century. In recent years the Salem limestone has attracted the attention of petroleum geologists, some of whom may not have had the opportunity of studying surface exposures of this formation. The stops and their sequence have been carefully chosen to present a unified view of the geology of the Salem and associated formations; features of stratigraphic, economic, and paleontologic interest will be seen. Participants will have the opportunity not only of examining the Salem limestone but also of studying a significant part of the Harrodsburg and St. Louis limestones and a complete section of the Ste. Genevieve limestone. The Aux Vases, Paoli, and Beaver Bend formations of early Chester age also may be observed. In order that participants may learn more about the geology of the conference area, a short summary of its physiography and many physiographic notations in the road log have been included in the guidebook.
