Geochemistry of magnesian granulites in feldspathic lunar meteorites Allan Hills A81005 and Dhofar 309
Magnesian granulites in Allan Hills A81005 and Dhofar 309 may possess the geochemical signature of the Moon's Feldspathic Highlands Terrane (FHT). Previous work on Apollo granulites suggests the presence of a high Mg/Fe, ...
Kirchhoff Common Offset Migration Velocity Analysis via Differential Semblance
This work gives an efficient and fast approach to obtain an accurate velocity model for seismic imaging. An accurate velocity model is prerequisite for obtaining the image that represents the true underground geological ...
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, ...
Climate variability and glacial history from the LGM to the present in a southern Patagonia tidewater glacier system
The study of tidewater glacier systems from the Last Glacial Maximum to the Present in southern Patagonia provides a relatively continuous high-resolution sedimentary record of climate change. This record enables us to ...
