Some Coal Measure Sections Near Peytona, West Virginia. 



By Be7ij. Smith Lyman. 



(Read before the American Philosophical Society, November 2, 1S94.) 



Some results of a couple of rough surveys made in 1872, near Pej'-tona, 

 Boone Co., W. Va., though without any addition from later observations, 

 maybe a useful contribution towards the elucidation of the geology of 

 that region. The graphic comparison of columnar sections there with 

 Prof. J. J. Stevenson's careful general section in the northern edge of 

 that State, as published, without any diagram, in our Transactions, Vol. 

 XV, p. 15, 1872, shows a remarkable general agreement, considering the 

 great distance. The present sections also help very much in the identifi- 

 cation of the different coal beds of the region, hitherto insufficiently studied, 

 as remarked by Prof. I. C. White, in his valuable "Stratigraphy of the 

 Bituminous Coal Field of Western Pennsylvania, Ohio and West Vir- 

 ginia," U. S. Oeol. Surv. Bulletin, No. 65, p. 148, 1891. 



It will be well to indicate first, with some precision, the situation of the 

 tracts surveyed, and then briefly their main topographical features ; be- 

 fore giving the geological details of the general structure and of the 

 special observed facts, and pointing out the remarkable agreement of the 

 resulting columnar sections with the distant northern section, and discuss- 

 ing the identification of beds that is consequently to be inferred. 



SITUATION. 



The accompanying small map shows in a general way the situation of 

 the two tracts and their relative position.
