HA-0711-M. MISSOURI. Correlation of regional geohydrologic

units to geologic formations in southern Missouri, by B. J. Smith and J. L. Imes. 1991. Two sheets. Sheet 1, 40 by 29 inches; sheet 2, 30 by 29 inches (all in color). $5.25.

The geologic history of southern Missouri includes several periods of inundation by ancient seas, during which substantial quantities of sediment were deposited and lithified, and intervening periods of uplift, during which large quantities of the lithified

sediments were eroded. These rocks and the basement crystalline rocks on which the sediments were deposited have been grouped into eight regional geohydrologic units. Six geohydrologic sections showing the correlation between the regional geohydrologic units and corresponding geologic formations are presented.
