Geochemical Diagnostics of Metasedimentary Dark Inclusions: a Case Study from the Peninsular Ranges Batholith, California
Dark enclaves rich in amphibole and biotite are ubiquitous in granitoid rocks and generally thought to represent fragments of mafic magmas, cumulates or restites. However, magmatic assimilation of metamorphic or sedimentary ...
Converted modes in subsalt seismic exploration
Salt has unusual properties which complicate seismic exploration. A Model study examines some problems encountered in subsalt amplitude analysis and demonstrates that traditional techniques for detecting hydrocarbons and ...
Pliocene-Pleistocene depositional sequences of the northern Gulf of Mexico, offshore Texas and Louisiana
This work tests the consistency of sequence stratigraphic methods by comparing the model documented in this study with previous models for growth faulted, siliciclastic environments. Interpretations derive from sequence ...
Tomographic study of mantle structure beneath eastern Asia
A high-resolution 3D P-wave velocity model of the mantle beneath eastern Asia was obtained through performing seismic travel-time tomography by using recently emerging new datasets. An improved relocation method that ...
Volatile cycling and the thermal evolution of planetary mantle
The thermal histories of terrestrial planets are investigated using two parameterized mantle convection models for either Earth like planets and planets with no active plate tectonics. Using parameterized models of mantle ...
