HUBBARD AND CRONEIS 
Ordovician, The fauna, (what little can be found) of the Moc- 
casin is also present in the Sevier so that there is no great differ- 
ence in the age of these two formations. Late Utica, Eden and 
possibly early Lorraine, seem to be the times in the New York 
Ordovician scale, which are comprised in the Sevier of Giles 
County. 
The Sevier Subdivided at the Narrows Section.

1. A hard, blue, even-bedded non-fossiliferous limestone, ex- 
hibiting the characteristic Sevier cleavage. One layer. 
11/2 feet. 
2. Gray, crumbly shale, weathering to clay. 2 feet. 
3. Even-bedded limestones and shales. The former in four 
to eight inch layers, blue to dark blue, hard, and all but non- 
fossiliferous. The shales are in two layers, one being green and 
the other yellow, besides many shale partings. The jointing gives 
cuneiform pits in the limestone. Fossils begin in this horizon. 
18 feet. 
4. Calcareous shales and thin limestones like the upper part 
of this formation, but more of a greenish gray color, and more 
crumbly. Soft with few fossils. This is the end of the transition 
from the Moccasin. A partly covered area. 20 feet. 
5. Blue limestone in beds of one to eight inches. Fossils un- 
common. A little shale and some calcite veins. 8 feet. 
6. Shale with a slaty cleavage, dark blue, green and black 
in color. Fissile, much jointed and thin bedded. The shale is 
rather calcareous. Fossils are rare. 19 feet. 
7. Thin limestones with a few interbedded thin shales. The 
limestones one inch to one foot in thickness, being dark gray to 
blue but weathering lighter and leaving much residual clay. 
Calcite veins are numerous and branching and some are as much 
as an inch and a half in thickness. This division is fossiliferous 
with the shells being much broken. The veins and fossils both 
weather out. Much jointed and cracked. Shale partings occur 
and are from paper thickness up to six inches, but they are not 
arenaceous. The beds are bent, crumpled, and folded as well as 
being faulted locally. Very fossiliferous. The brachiopods Dal- 
manella testudinaria and possibly suhaequata and Plectamhonites 
sericeus being very common and characteristic. 386 feet.
