June, 1921] Steel Molding Sand in Ohio 261 



THE MASSILLON SANDSTONE. 



As the section of the Pottsville formation given on a pre- 

 ceding page shows, the ]\lassillon sandstone is divided into two 

 parts by the Quakertown or No. 2 coal. At Massihon, the 

 type locality, the Upper Massillon sandstone, GO feet thick, 

 is well shown in the Everhard quarry on the west bank of the 

 Tuscarawas River, while at Pauls, about 4 miles farther up 

 stream, the Lower Massihon sandstone was formerly quarried. 



The following section in the Everhard quarry shows very 

 well the rock succession: 



Ft. In. 



Upper Massillon — Stripping, rejected 12 



Sandstone, much broken, iineven bedded, coarse- 

 grained, not as good as sandstone below with 



which it is mixed in proportion of 1 to 2 25 



Clay shale, rejected 10 



Sandstone, massive, used for silica sand 35 



Shale, part siliceous 33 



Anthony coal, bony 2 



Sciotoville clay, siliceous, light-colored 8 6 



Shale, dark-colored 3 



In Holmes County, southwest of Massihon, the two sand- 

 stones are well developed. The lower division is represented 

 partly by shales, but the upper division appears to consist 

 more largely of sandstone.^ The rock is well developed in 

 Muskingum County where in places it is slightly con-' 

 glomeratic." Along the western border of the Hocking Valley 

 coal field, Orton reports both members of the Massillon sand- 

 stone present, the upper in places very pure and from 10 to 20 

 feet thick, while the lower is "often heavy. "•'^ In Scioto 

 County in the extreme southern part of Ohio, thick sandstones 

 on the horizon of the Massillon are shown in numerous sections.* 



From what has just been said, it appears that the Massillon 

 sandstone extends across the State much as does the Sharon 

 conglomerate, though the latter by reason of its texture is 

 much the more conspicuous. 



The Massillon sandstone is used in a large way at Massillon 

 for steel molding sand and several other purposes. It was 

 formerly quarried for building stone and many structures of 

 it may be seen in Massillon and near-by cities.
