Summary:

Named Myers shale for Myers place in the Meadow Brook valley, Berkeley Co., WV. Consists of largely bright-red crumbly shale and thin argillaceous sandstones, with, at base, thick cross-bedded dirty-gray gritty sandstone 60 feet thick. Unit is greater than 800 feet thick. It underlies the Pinkerton sandstone and overlies the Hedges shale; all are included in the Pocono group. The Myers is of Mississippian age.

Summary:

The Meadow Branch synclinorium, Berkley Co., WV, is composed of five formations: Rockwell, Purslane, Hedges, Myers, and Pinkerton, for many years assigned to the Pocono Group. The three basal units are retained as Early Mississippian (Kinderhookian and Osagean). Only the Purslane is correlative with the original Pocono Formation of northeastern PA. The Myers is 396 m thick in the Meadow Branch synclinorium, and consists for the most part of red shale. A basal yellow-buff sandstone approximately 30 m thick is here informally named the Little Mountain member. The Myers Shale is now correlated with the Late Mississippian (Meramecian) Maccrady Formation of southwestern VA. The Little Mountain member, however, is not known outside the synclinorium. The Myers was erroneously mapped as Hampshire on the WV State geologic Map (1968).
