New geochemical data from the Villa de Cura indicate that it is a subducted (and exhumed) island-arc terrane. The majority of the basalts are primitive island-arc tholeiites (44.8--51.5 wt% SiO2, 6.7--22.8 wt% MgO). REE ...

Attempting to image the subsurface in areas of complex geology and rapid lateral velocity variation is a challenging problem. In particular, using prestack Kirchhoff migration in conjunction with first arrival travel times ...

A new computer program for strain visualization has been written. Given an upper triangular deformation tensor, which corresponds to homogeneous deformations where no shearing occurs in the z-direction (assuming a right-handed ...

This sequence stratigraphic analysis examines an Oligocene to Miocene carbonate platform from the Northwest Shelf of Australia. Five Oligocene sequences, eleven Miocene sequences and one Pliocene sequence are identified ...

Multiple isotopic and geochemical tracers were employed to unravel the complex history of recent environmental variability at Cocos Island. Downcore variations in delta18O, U/Ca, Sr/Ca, and Ba/Ca within coral skeletal ...
