1 Brown, Francis HaroldGeological development of the Omo-Turkana Basin during the pliocene and pleistocene epochsPliocene and Pleistocene deposits of the Omo-Turkana Basin extend from 6?N latitude to about 2?N latitude (-450 km), and laterally from about 35.5?E to 36.5?E. Sediments are brought to the basin by the Omo River which rises in Ethiopia, and by the Turkwel and Kerio Rivers which rise in Kenya and Uga...2004
2 Zhdanov, MichaelThree-dimensional inversion of large-scale EarthScope magnetotelluric data based on the integral equation method: geoelectrical imaging of the Yellowstone conductive mantle plumeInterpretation of the EarthScope MT (magnetotelluric) data requires the development of a large-scale inversion method which can address two common problems of 3D MT inversion: computational time and memory requirements. We have developed an efficient method of 3D MT inversion based on an IE (integ...2011

8 Miller, Jan D.Analysis of the surface potential developed by non-reactive ionic solidsThe sign of the surface potential for complex non-reactive ionic solids cannot be predicted solely from consideration of the hydration energy of gaseous ions which constitute the ionic lattice. Accurate analysis of these systems must involve the hydration energy of surface ions, which requires knowl...Lattice; dipole; Madelung Constants1976
9 Miller, Jan D.Spectroscopic analysis of passivation reactions for carbonaceous matter from carlin trend oresAbstract. Three different refractory carbonaceous gold ores from the Carlin operation in northeastern Nevada were investigated to characterize the effect of passivation treatments on the nature of the carbonaceous material. The carbonaceous material was chemically isolated from the ores and pass...Gold; Chlorine; Cyanidation1990
10 Chapman, David S.; Allis, Richard GeorgeLate Neogene exhumation patterns in Taranaki Basin (New Zealand): evidence from offset porosity-depth trendsTaranaki Basin, New Zealand, is located adjacent to the Australian-Pacific Plate boundary where the tectonic regime changes from dominantly subduction-related to the north to transpression-related along the Alpine Fault to the south. During the Neogene, burial and exhumation varied extensively, in ...Neogene; Uplift; Exhumation; Taranaki Basin; New Zealand1998
11 Reichler, Thomas J.Multidecadal drought cycles in the Great Basin recorded by the Great Salt Lake: modulation from a transition-phase teleconnectionThis study investigates the meteorological conditions associated with multidecadal drought cycles as revealed by lake level fluctuation of the Great Salt Lake (GSL). The analysis combined instrumental, proxy, and simulation datasets, including the Twentieth Century Reanalysis version 2, the North Am...2012-01-01
12 Miller, Jan D.; Herbst, John A.Factors affecting droplet size distributions produced in dispersed phase mixersDroplet size distributions were determined by stabilizing in gelatin and measurement of the distributions by means of computerized image analysis. Several variables that affect droplet sizes were studied and the resulting size distributions were modeled via a population balance equation. Key paramet...Gelatin; Phases; Agitating1981
13 Miller, Jan D.; Yost, Garold S.; Veranth, John M.Novel method to detect unlabeled inorganic nanoparticles and submicron particles in tissue by sedimentation field-flow fractionationA novel methodology to detect unlabeled inorganic nanoparticles was experimentally demonstrated using a mixture of nano-sized (70 nm) and submicron (250 nm) silicon dioxide particles added to mammalian tissue. The size and concentration of environmentally relevant inorganic particles in a tissue sa...Sedimentation field-flow fractionation; Transmission electron microscopy; Tissue digestion2008
14 Chapman, David S.Exhumation of the central Wasatch Mountains, Utah: 1, Patterns and timing of exhumation deduced from low-temperature thermochronology dataThe Wasatch Mountains are often cited as an example of normal fault growth and footwall flexure. They represent a tilted footwall at the edge of the Basin and Range extensional province, a major rift basin. Thus understanding the detailed spatial and elevation changes in coupled thermochronometer da...Uplift; Exhumation; Wasatch Fault; Wasatch Mountains; Utah; Helium dating; Fission track; Tectonophysics; Extensional tectonics; Geothermal observations2002
