Quantitative Constraints on the Rate of Landform Evolution Derived from Low-Temperature Thermochronology
In recent years, the nature of the complex interactions between the solid earth and the overlying atmosphere has been the subject of much debate (England and Molnar 1990; Whipple et al. 1999; Braun et al. 1999). Does erosion play an important role in the dynamics of mountain building? Is there a strong feedback into the balance of forces at the crustal scale from mass transport by erosional and...
متن کاملTopographic Evolution of the Sierra Nevada Measured Directly by Inversion of Low-temperature Thermochronology
At present, there are at least two competing ideas for the topographic evolution of the Sierra Nevada. One idea is that the Sierra Nevada was formed as a monocline in the Cretaceous, marking the transition from the Great Valley forearc basin to the west, and a high Nevadaplano plateau to the east, similar to the west flank of the modern Altiplano of the Andes. Both the thermochronologic imprint...
متن کاملExhumation of the central Wasatch Mountains, Utah: 1. Patterns and timing of exhumation deduced from low-temperature thermochronology data
[1] The 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 data, and how these changes can be interpreted, may aid in the analysis of thermochronometer da...
متن کاملAfterglow, low-temperature radioluminescence and thermoluminescence of Lu2O3:Eu ceramic scintillators
Comparison of thermoluminescence (TL) and scintillation light outputs with continuous gamma-ray excitation reveals that the concentration of deep hole traps in ceramic Lu2O3:Eu, tentatively attributed to anion Frenkel defects, is enhanced by reversible radiation damage. Shallow electron and hole traps are tentatively attributed to surface states at grain boundaries. Electrons in shallow traps s...
متن کاملCan low-temperature thermoluminescence cast light on the nature of ultra-high dilutions?
Low-temperature thermoluminescence has been used in attempt to understand the particular structure of ultra high dilutions. Samples are activated by irradiation after freezing at the temperature of liquid nitrogen (77 degrees K). Experimental results show that, in the course of rewarming, the thermoluminescent glow is susbtantially different between dilutions of different substances. It is sugg...
