IRON ORES OF THE CLINTON FORMATION 2^ 



Wolcott, Wayne co. The section of the Clinton at Wolcott, 

 condensed from the record of the recent test hole, is as follows. 



STRATA FEET 



Shaly limestone 13 



Dark colored shale, with graptolites 44 



Ore, fossil i 



Pentamerus limestone ^2 



Shale >. 62 



Shaly limestone, lower Pentamerus 13 



Ore with limestone seam 2 



Shale 2+ 



The drill did not penetrate through the lowest Clinton shale which 

 probably extends 3 or 4 feet below the bottom of the hole. Esti- 

 mating the thickness of this shale at 6 feet, the Clinton beds aggre- 

 gate 164 feet, as compared with 135 feet at Wallington. 



The upper hematite seam here shown must disappear within a 

 comparatively short distance to the east, since it was not found in 

 the hole at Red Creek. It is present, however, just north of Alton, 

 on Second creek, 10 miles west of Wolcott, but thins out entirely 

 before Wallington is reached. The lower Pentamerus limestone is 

 here quite shaly, containing fewer fossils than farther west. East of 

 Wolcott it is scarcely recognizable. The Hmestones generally be- 

 come less important after the belt passes Wayne county. Through- 

 out the eastern part they never form solid masses of any size but 

 are always in thin layers with shale intercalations. 



Red Creek, Wayne co. The test hole at this place was drilled 

 to a depth of 178 feet before reaching the ore horizon. The section 

 of the Clinton may not be complete. The greater part of the hole 

 was in shale, with limestone between 86 and 103 feet, representing, 

 perhaps, the upper Pentamerus. About 2 feet of limestone, repre- 

 senting the lower Pentamerus, was found just above the ore. The 

 complete record is given elsewhere. 



Auburn, Cayuga co. A deep well was drilled during 1897-98 

 about \y2 miles north of Auburn. The locality is 24 miles south 

 of the Clinton outcrop at Fair Haven. The strata assigned to the 

 Clinton by Prosser^ consisted of green noncalcareous shale, 10 feet, 

 and clear green argillaceous shale, 1 15 feet. Since no samples were 

 inspected from 1290 feet when the drill was in T.ixkport limestone
