Interpretation of low‐temperature thermochronometer ages from tilted normal fault blocks Open
Low-temperature thermochronometry is a widely-used tool for dating the timing and rate of slip on normal faults. Rates are often derived from suites of footwall thermochronometer samples, but simple 2D regression of age vs. structural dept…
THE INFLUENCE OF LITHOLOGY ON THE FORMS OF HILLSLOPES AND DRAINAGE BASINS IN SOIL MANTLED LANDSCAPES Open
Much of the Earth's surface is blanketed by a mantle of soil and weathered rock. In these settings, topographic forms are typically smooth, with convex hillslopes grading subtly into the concave valley networks that define drainage basins.…
Lithologic controls on the form of soil mantled hillslopes Open
Slopes in steady-state soil-mantled landscapes tend to increase downslope in a way that balances local transport capacity with the sediment supplied from progressively larger source areas. Most formulations of sediment transport due to hil…
