Summary:

In this report, Greenbrier Limestone divided into (ascending) Little Valley Limestone Member, St. Louis Limestone Member (Hillsdale Member of Reger, 1926), the "St. Genevieve" Limestone Member, and the Gasper Limestone Member. The St. Louis (or Hillsdale) consists of dark-gray to grayish-black cherty limestone. The chert is black, pale red, or gray and occurs as stringers or nodules. Contains fossils considered to be diagnostic of the Meramecian St. Louis Limestone of MO.
