J.H. Sass, P. Morgan
1988, Journal of Geophysical Research Solid Earth (93) 6027-6039
Over 5% of heat in the western United States is lost through Quaternary silicic volcanic centers, including the Valles caldera in north central New Mexico. These centers are the sites of major hydrothermal activity and upper crustal metamorphism, metasomatism, and mineralization, producing associated geothermal resources. We present new heat flow...
The surface integral approach to Radarclinometry
R.L. Wildey
1988, Earth, Moon and Planets (41) 141-153
Because radarclinometry is fundamentally describable in terms of a nonlinear, first-order, partial differential equation, one expects that it can, in principle, be carried out by direct deterministic integration beginning at a given threshold profile along the azimuthal coordinate. Such a boundary condition could be provided by the altimetry profile obtained...
Hydraulic fracturing in situ stress measurements to 2.1 km depth at Cajon Pass, California
J. H. Healy, Mark D. Zoback
1988, Geophysical Research Letters (15) 1005-1008
Stress measurements to 2.1 km reveal stress changes with depth that cannot be explained by an elastic response to uniform crustal strain. The data at about 1 km depth suggest that the stress is limited by the frictional strength of rock and is perturbed at greater...
Three decades of geochronologic studies in the New England Appalachians
R. E. Zartman
1988, Geological Society of America Bulletin (100) 1168-1180
Over the past 30 years, both isotope geochronology and plate tectonics grew from infancy into authoritative disciplines in the geological sciences. Previously, mountain systems like the Appalachians had been viewed almost entirely in the context of the classical geosyncline, implying a gradualism in stratigraphic and structural change throughout the orogen....
