PULASKI SHALE 



449 



qiienth' along the strike of the same beds. 

 $^our or five beds of sandstone, 2 to 15 feet 

 thick, occur with the shales. No fossils 

 were found in the formation, though care- 

 ful search was made for them. The meas- 

 ured thickness along the Dublin-Pearisburg 

 road is 2,578 feet, but, as explained above, 

 this is not the total thickness. The top of 

 the Pulaski of the southern line of outcrop, 

 which occurs typically in Little Walker and 

 Cloyds Mountains, is faulted out wherever 

 the writer has examined it, and this seems 

 to have been the case wherever measure- 

 ments were made by Campbell, Stevenson, 

 and Fontaine. Occasional presence of mud 

 cracks, absence of fossils, and variability of 

 sediments in character and color indicate 



subaerial origin.
