WAVERLY SERIES OF CENTRAL OHIO 20 y 



"Waverly sandstone series " for the rocks occurring between the 

 "argillaceous slaty rock, or shale stratum," now known as the 

 Ohio shale, and the "conglomerate" which lies at the base of 

 the Coal-measures. Waverly is the name of the capital of Pike 

 county in southern Ohio and Professor Briggs stated that "As 

 some of the most beautiful stones that have been obtained were 

 quarried at Waverly, we may, for the present, denominate these 

 rocks the Waverly sandstone series." 1 



In the following report, for some reason, Professor Briggs 

 used the term "fine-grained sandstone" in place of the Waverly 

 in his descriptions of the geology of Hocking, Athens, and Craw- 

 ford counties. 2 



In the first report of the Newberry survey, Dr. Newberry and 

 Professor Andrews revived the name, "Waverly sandstone." 3 

 Professor Andrews stated that it consisted of "A group of sand- 

 stones and shales, measuring on the Ohio River 640 feet in thick- 

 ness (from the black slate to the base of the sub-Carboniferous 

 limestone in the Kentucky hills), [which] rests conformably upon 

 the black slate." 4 He further described a stratum of bituminous 

 black shale 16 feet in thickness, 137 feet above the base of the 

 group to which he gave the name "Waverly black slate." 5 It 

 was also stated that between the Coal-measures and Waverly in 

 Hocking county was "a group of comparatively fine-grained, 

 buff-colored sandstone," 133^2 feet in thickness which was 

 named the Logan sandstone." 6 Below the Logan sandstone 

 was given 85 feet of rocks which were stated to be composed of 

 fine-grained sandstones alternating with conglomerates and this

 of the strata of Ohio, facing p. 109. The same term was used by Mr. Foster, another 

 assistant; see pp. 76 and 103, and, facing p. 73, his "Geological section along the 

 National road from the Scioto River to the eastern line of Muskingum county."

 Coal Measures " at the close of this report gave the thickness of the Logan sandstone 

 group as 144 feet.
