Oblique collision and accretion of the Netherlands Leeward Antilles island arc: A structural analysis of the Caribbean-South American plate boundary zone
The Netherlands Leeward Antilles volcanic island arc is an ideal natural laboratory to study the evolution of the Caribbean-South American plate boundary. The Leeward Antilles islands (Aruba, Curacao, and Bonaire) are ...
Characterizing the southeast Caribbean-South American plate boundary at 64°W
The crustal and lithospheric structure of the northern South America plate boundary with the southeast Caribbean has been the focus of many studies. In this region, westward subduction of (Atlantic) oceanic South America ...
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 ...
Using elastic-wave seismic data to image an ultra shallow buried paleochannel
This thesis is a case study concerning the application of reflection seismic methods to a very specific instance: mapping an extremely shallow underground feature in the framework of groundwater contamination and remediation ...
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 ...
