ANTHONY COAL 



Stratigraphy and Extent 



The Anthony coal horizon consists of a thin deposit of coal and 

 interbedded dark carbonaceous shales, lying directly over the Scioto- 

 ville clay. Although not a continuous deposit, it has been traced from 

 the Ohio River through eastern Scioto and Pike, Jackson, Hocking, 

 Perry, and eastern Licking counties, as far northward as southwestern 

 Muskingum County. 1 In Scioto County, where the lowest members of 

 the Pottsville formation are present, including the Harrison ore, the 

 Sharon conglomerate, coal, and ore, with their associated sandstones 

 and shales, the Anthony coal and the underlying Sciotoville clay 

 occur as much as 60 feet above the base of the formation. In Jackson 

 County the interval is only one-half as great, while in Hocking County 

 at Logan it lies a few feet above the Logan sandstone, and rests directly 

 upon the Maxville limestone at Maxville in Perry County. 



The Anthony coal does not form a continuous, well-marked horizon, 

 and where present, is thin, varying from a mere trace to 3 feet in thick- 

 ness. It attains its maximum development in Scioto and Jackson 

 counties, where the thickness averages less than a foot, but it is often 

 represented by a layer of only 2 or 3 inches. A trace was noted in two 

 localities in Vinton County; 2 near Logan in Hocking County and at 

 Maxville in Perry County a few inches of shaly coal was reported, 

 while in Muskingum County a thin layer of carbonaceous shale or 

 sometimes only a soot streak marks the horizon. The coal, where thick, 

 is of good quality and is in many places cannel; it is, however, generally 

 shaly or interbedded with dark, carbonaceous shales. In a few places 

 in Scioto and Jackson counties, it is mined for household use. 



Description of Geologic Sections and Collecting Localities 



Scioto County. At the mine of the Wm. E. Dee Clay Product 

 Co. near Scioto Furnace, the dark carbonaceous shales on the Anthony 

 coal horizon were found to be fossiliferous. Small, excellently pre- 

 served specimens of Lingula occur in great profusion between the lay- 

 ers, and with the exception of a few other rare forms, are the only 

 fossils found. The section at this locality follows (Locality 7) :
