CLASSIFICATION OF THE GEOLOGICAL FORMATIONS OF TENNESSEE 



BY JAMES M. SAFFOED • 



In the spring of 1900 I had occasion to construct a table of formations for a 

 small text-book on the geology of Tennessee.* 



The table includes the more recently recognized formations, introduces some 

 changes, and notices certain errors that have been made. It was constructed, as 

 will be seen, for Tennessee. Local names are used in many cases and for two 

 reasons: first, to bring the subject more nearly home to the student, and, second, 

 because many of the formations have a more or less local development. 



For brief descriptions of the formations, other than those contained in the table 

 and notes, the reader is referred to the text-book cited in the foot-note.
