CORRELATIONS 



That the limestone series of Baylor County is the equivalent 

 of the "Albany" formation of the southern area is fully established 

 by both the stratigraphic and the faunal evidence. The beds in the 

 northern area, which include the limestones, shales, and sandstones of 

 Baylor County and the sandstones and shales of Archer and Wichita 

 counties, constitute the Wichita formation. Our investigations 

 therefore fully support the conclusions of Cummins 1 and Adams 2 as 

 to the equivalency of the "Albany" and Wichita formations. 3

3 Along with the limestones of northeastern Baylor County which Cummins 

 has designated as the top of the Wichita the writer would include the overlying beds 

 of shale and limestone mapped by him as Clear Fork, which outcrop in the banks of 

 the Big Wichita about a mile east of the Seymour- Vernon road and northward on 

 Beaver Creek.
