THICKNESS 



Honiewood sandstone. Heavy, buff, coarse-grained 

 sandstone, rather soft and micaceous. A few rods 

 farther south this sandstone is much thicker and 

 shows disconformity associated with cross-bed- 

 ding, folding and faulting in the lower part. 



Gray arenaceous shale. About 1| or 2 feet below the 

 sandstone is a concretionary layer in the shale. 



Bluish-black shales which are very thin and break 

 into very small pieces. 



Upper Mercer limestone, with limonite ore. There 

 are four layers of the limestone shown, the upper 

 one 6 to 8 inches thick and containing iron ore, the 

 next a 5-inch layer without a conspicuous amount of 

 ore, a 5-inch layer with iron ore, and the lowest a 

 10-inch layer without the ore. The limestone is 

 dark gray, weathering almost black except where 

 the iron ore gives it a dark red or brown color. 

 Fossils appear to be. very scarce. 



Covered to water level. All of the lower part of the 

 section, from the road on the dugway to river level 

 belongs in the Pottsville formation.

 being very fossiliferous, with remains of trees,

I. Hoynewood sandstone. Topof the Pottsville formation. 

 The sandstone is very thick and massive, some of 

 the layers being 10 feet thick. It is coarse and 

 micaceous; and is a dark steel-gray in color, 

 sometimes iron-stained. Below the floor of the 

 quarry 20 feet more of Homewood sandstone are 

 said to be buried.
