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 ...
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 ...
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 ...
