ostracodes, arenaceous Foraminifera, and scat- 

 tered fish bones. 



3. Unfossiliferous, poorly-sorted pea gravel in- 

 terlayered with red to brown sideritic sandstone 

 and mudstone. Siderite, gray-brown, and yellow in 

 color, occurs as rosettes, bladed aggregates, and 

 globular aggregates that comprise a few grains to 

 as much as 80 percent of individual samples. Ac- 

 cessory minerals include blood-red hematite ag- 

 gregates (abundant), pyrite both as euhedral 

 crystals and cementing material (common), and 

 mica (common). 



The overlying sediments of the Tuscaloosa For- 

 mation of Late Cretaceous age resemble the upper 

 part of the Lower Cretaceous rocks in color and 

 gross composition. However, siderite is absent in 

 the Tuscaloosa Formation in this area. In addi- 

 tion, the Tuscaloosa Formation in the area con- 

 tains milky-white chalcedony and crenulate green 

 mica (chloritic ?) aggregates that serve to differ- 

 entiate it from underlying rocks.

 ceous age are described, are located in Figure 1,
