Nature of the angular unconformity between the Paleozoic metasedimentary rocks and the mesozoic metavolcanic rocks in the eastern Sierra Nevada, California
C.A. Brook, Warren J. Nokleberg, Ronald W. Kistler
1974, GSA Bulletin (85) 571-576
Two major wall-rock sequences, the Paleozoic metasedimentary rocks and the Mesozoic metavolcanic rocks, in the eastern Sierra Nevada, California, are separated by an angular unconformity rather than by a fault as has been proposed by other investigators. The unconformity is parallel to formation contacts in the younger metavolcanic rocks and...
K-Ar Age Relations of Granodiorite Emplacement and Tungsten and Gold Mineralization near the Getchell Mine, Humboldt County, Nevada
Miles L. Silberman, B. R. Berger, Randolph A. Koski
1974, Economic Geology (69) 646-656
A granodiorite stock intrudes complexly folded and thrust-faulted Paleozoic sedimentary rocks in the Osgood Mountains of eastern Humboldt County, Nevada. Within the metamorphic aureole surrounding the pluton, the sedimentary rocks are converted to cordierite hornfels and marble; tungsten-bearing tactites developed along the contacts of the granodiorite. Cutting the granodiorite and...
The soil creep-curved tree fallacy
Richard L. Phipps
1974, Journal of Research of the U.S. Geological Survey (2) 371-377
No evidence has been found in eastern deciduous forests to substantiate statements that curved tree trunks, downslope tilted tree trunks, and upslope trailing tree root systems are the result of soil creep. Curvature and tilting of trunks are described as geotropic and phototropic responses to physical and physiological conditions unrelated...
