Abstract

"Quaternary deposits preserved in a karst trap on the Lebanon uplands a e described. The sediments represent the Yarmouthian, Illinoian, Sangamonian, and Wisconsinan Stages. The karst trap is pre-Yarmouthian in age. The lowermost deposit consists of residual fill material on which lies a well-developed Yarmouth paleosol. During the Illinoian Stage about 61 cm (2 feet) of Loveland loess was deposited over the area. Toward late Illinoian conditions favoring erosion rapidly filled the closed system, stripping the loess and reducing the residual slopes. The system stabilized during the Sangamonian Stage allowing for a thick, strong Sangamon paleosol to deve lop on the Illinoian fill material which is tentatively named the Mullic a ne School Formation. By the time the Wisconsin loess began to be deposited, the Sangamonian and Illinoian deposits for the most part had already been removed from the surrounding uplands. During the Wisconsinan Stage 122 cm (4 feet) of loess was deposited over the Sangamon surface in the system. The modern soils in the system were developed in late Wisconsin loess.

The closed system studied has served as a repository for Quaternary sediments most of which have been completely eroded from the surrounding Ozark uplands"-- Abstract, p. ii
