Book excerpt: Excerpt from The Geologic Setting of the John Day Country: Grant County, Oregon Thomas Condon Viewpoint, John Day Fossil Beds State Park. From Picture Gorge to the cliffs opposite, the Picture Gorge Basalts and varicolored ash beds of the John Day Formation rise together nearly 2000 feet. The basalt that caps Sheep Rock is an erosional remnant. The lower beds in the John Day Formation are colored red by clay eroded from thick soil on the Clarno Forma tion, which is exposed in the farthest red hill. The soil was formed by tropical weathering some 30-35 million years ago, before the John Day Formation was laid down. Faulting on a small scale is illustrated in Sheep Rock, where the thick olive-drab ash flow in the middle of the John Day Formation is offset 75-100 feet (fig. The fault slopes about 45 eastward. About two miles down stream, large - scale movement on two faults has dropped the basalt flows in Middle Mountain 2000-2500 feet. One of the faults fol lows along the upstream base of Middle Mountain. Fig. 5. - North-south section along the John Day River through Picture Gorge and Middle Mountain.

Book Synopsis The Geology of the East Central Desolation Butte Quadrangle, Grant County, Oregon by : Neil Elfrink
Download or read book The Geology of the East Central Desolation Butte Quadrangle, Grant County, Oregon written by Neil Elfrink and published by . This book was released on 1987 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pre-Tertiary metamorphic rocks, Jurassic granitic intrusions, and Eocene basalts are exposed along the North Fork of the John Day River at its confluence with Granite Creek. Geochemical and textural evidence suggest greenschist-metamorphosed, strongly sheared, volcanogenic rocks originated in an island-arc environment. These greenstones were apparently intruded during the Late Permian by a silicic pluton that is similarly metamorphosed and brecciated. South of this arc terrane, tectonically disrupted ophiolitic rocks are exposed. This east-west-trending belt of melange contains blocks of chert, metagabbro and metabasalt in a serpentinite matrix. Titanaugite indicates the original basalt may have been alkalic. Paleozoic or Triassic Elkhorn Ridge Argillite underlies much of the thesis area and consists mostly of contorted chert and argillite. Graywackes, greenstones and limestones are intercalated with Elkhorn Ridge Argillite. Regional metamorphism is lower greenschist facies. Two relatively fresh granitic stocks may be satellites of the Upper Jurassic Bald Mountain batholith exposed nine kilometers to the east. An intrusive sequence ranging from mafic quartz diorite to granite comprises the larger stock, exposed along Granite Creek. This pluton contains mostly quartz diorite and tonalite. A 0.5 kilometer wide stock of porphyritic tonalite intrudes argillite on the north side of the North Fork, John Day River canyon. Mineral assemblages in the contact metamorphic aureoles around the two stocks are characteristic of hornblende hornfels facies. Tertiary dark gray basalt overlies the Mesozoic and Paleozoic rocks at a profound unconformity. Geochemistry suggests the olivine-bearing, vesicular basalt is equivalent to the Clarno Formation exposed farther to the west.
