Crustal structure across the Caribbean-South American plate boundary at 70W: Results from seismic refraction and reflection data
The Caribbean-South America diffuse plate boundary is characterized by tectonic transpression with oblique convergence. In northwestern Venezuela, the underthrusting of the Caribbean Plate beneath northwestern South America, ...
Horizontal thermal contractional strain of oceanic lithosphere: The ultimate limit to the rigid plate hypothesis
Depth-averaged horizontal strain rates in oceanic lithosphere due to thermal contraction are determined. Calculated strain rates range from ≈10 -2 Myr-1 (near the mid-ocean ridge) to ≈10 -5 Myr-1 (for the oldest ...
Thermal history, continental growth, and the Urey ratio: How continental growth affects the thermal evolution of the Earth
Early thermal history models predicted a high Urey ratio (>0.7), in contrast to more recent geochemical estimates of 0.15-0.6. To potentially help resolve this discrepancy, we explore the effects of adding continental ...
