Abstract:: The Tumalo quadrangle lies approximately 30 kilometers behind the Cascade volcanic arc and marks the southernmost extent of continuously exposed Deschutes Formation rocks. Deschutes Formation rocks in the Tumalo quadrangle include late Miocene volcaniclastic sedimentary rocks, ignimbrites and lapillistones, and late Miocene to early Pliocene basalts and basaltic andesites. Volcaniclastic...

Creator:: Heironimus, Thurman L.
Abstract:: During Early and Middle Devonian time, the main part of the Death Valley area was characterized by shallow marine shelf position.

Creator:: Little, Stephen W.
Abstract:: The Mitchell inlier in north-central Oregon contains the largest exposure of Cretaceous marine sedimentary rocks in this region. Nearly 9,000 ft of Albian-Cenamanian rocks are exposed along the flanks of the Mitchell anticline. The Cretaceous section rests unconformably overlain by Tertiary volcanic rocks. The Cretaceous rocks have previously been divided...
