LA MOREAUX Geologist United States Geological Survey Published in cooperation with United States Department of Interior, Geological Survey, Washing.ton, D. C. ATLANTA 1946 I LETTER OF TRANSMITTAL DEPARTMENT OF MINES, MINING AND GEOLOGY ATLANTA, February 15, 1946. His Excellency, Ellis Arnall, Governor Commissioner Ex-Officio, State Division of Conservation Through The Honorable Nelson M. Shipp, Assistant Commissioner SIR: I have the honor to submit herewith Georgia Geological Survey Bulletin No. 50, Part I, "Geology of the Coastal Plain of East-Central Georgia." This is the first in a series of bulletins under this title. Others will be published from time to time until all of the Cretaceous area in the State has been mapped. The geology of east central Georgia, the area covered in this report, influences in three essential ways the economy of the State: The Tuscaloosa formation consists of thick beds of sand and gravel that are excellent aquifers. These water-bearing beds will furnish large additional quantities of water of good quality for industrial and municipal uses throughout a belt of 10 to 30 miles in width along the northern mar­ gin of the Coastal Plain of Georgia. Georgia produces approximately 80 per cent of the national output of kaolin. The major portion of this production is from deposits described in this report in Washington, Wilkinson a:nd Twiggs counties. Other com­ mercial minerals mined in this area include bauxite, fuller's earth, lime­ stone, and sand and gravel.

Highway 66, one mile southwest of Kirkwood, Missouri. Dur­ ing the construction of the interchange, numerous artificial exposures of rocks of the middle Mississippian Meramecian Series were exposed. This provided an excellent opportunity for examining fresh exposures near the type Meramecian Ser­ ies. The formations of the area were studied, and starti­ graphic sections were prepared from three of the more com­ plete sections that were measured and described. The high­ way cuts expose complete sections of the Warsaw and Salem formations, and the lower part of the St.

Olive Prepared in cooperation with the KENTUCKY GEOLOGICAL SURVEY MISCELLANEOUS INVESTIGATIONS SERIES Published by the U.S. Geological Survey, 1980 G DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP 1-1217 UNITED STATES GEOLOGICAL SURVEY GEOLOGIC MAPS OF THE JACKSON PURCHASE REGION, KENTUCKY By Wilds W. Olive INTRODUCTION STRATIGRAPHY AND ENVIRONMENT The Jackson Purchase region, that part of Kentucky west of the CRETACEOUS Tennessee River, is in the northeastern part of the Mississippi em­ UPPER CRETACEOUS bayment, a broad south-plunging structural downwarp whose axis Tuscaloosa Formation approximately coincides with the east valley waU of the Mississippi The Tuscaloosa Formation in the Jackson Purchase region was first River. Rocks exposed in the region range in age from Devonian to recognized by Roberts, Gildersleeve, and Freeman ( 1945, p. 38-41), Holocene. Those of post-Paleozoic age are the principal subject of this report. The post-Paleozoic rocks consist entirely of clastic conti­ although a chert-gravel deposit, designated as Tuscaloosa by Wade nental and marine sediments, the oldest of which are Late Cretaceous (1917), had earlier been reported to extend from Tennessee into an in age. Although the Late Cretaceous stratigraphic record contains area of Kentucky now known as the Land-Between-the-Lakes­ gaps due to erosion and nondeposition, strata representing most bordered by Kentucky Lake on the west and by Lake Barkley on the stages of the Tertiary are present. Post-Paleozoic sediments attain a east. Wade's identification resulted from his tracing of discontinuous outcrops from Wayne County in southern Tennessee, where Miser maximum thickness of about 2,050 feet near the embayment axis at (1917, p.
