.... Recognition of domains with similar orientation and magnitude of transmissivity tensors is important for effective groundwater management. The Pen Argyl Member of the Martinsburg Formation is a thick sequence of claystone slate with subordinate intercalated quartzose slate and sub-graywacke. Time-drawdown...

... into commercial slate. Local, basic, igneous intrusives cut the Martinsburg. The Taconic Disturbance affected the Martinsburg from the Susquehanna Valley eastward, but not the other Ordovician clastic beds. This tectonic interval can therefore be dated post-Pulaski but pre-Richmond. Since it did not come...

...ROGER C. HOLEYWELL; TERRY E. TULLIS Abstract The outcrop of the Martinsburg and Shawangunk Formations at Lehigh Gap, Pennsylvania, is an important locality for studying the development of slaty cleavage because a gradual transition from shale to slate exists within a distance of 50 m. Field, thin...

... throughout the Paleozoic section, reflects at least two orogenies. Slaty cleavage is restricted to the Ordovician Martinsburg formation and predates overlapping Lower Silurian Tuscarora quartzite. The slaty cleavage is the only indication of metamorphism in the Paleozoic rocks. The slaty cleavage is a near...
