Layer-stripping reverse-time migration
Reverse-time migration has proven to be successful for structures with steep dips and strong velocity contrasts. Applying this algorithm to a large scale seismic model requires significant computational expense, particularly ...
Tectonic evolution of the south-central Caribbean based on geochemical data
Northern Venezuela consists of seven east-west trending tectonostratigraphic belts which are from north to south: Dutch and Venezuelan islands (DVI), Venezuelan platform, Cordillera de la Costa-Margarita terrane (CCMT), ...
Tertiary geology of the Quebrada Huaricangana area, East Pisco Basin, southern Peru: Late Paleogene to Neogene transgressive sedimentation within a forearc basin
Clastic packages studied in the southern East Pisco Basin represent the transgressive Late Eocene to earliest Oligocene Paracas Group, with questionable presence of the latest Oligocene to Early Miocene Chilcatay formation. ...
Geology and stratigraphy of the Mount Bennett Hills, and the origin of west-central Snake River Plain rhyolites
Voluminous mid-Miocene (8-13 Ma) rhyolitic ash-flows and lava flows (Idavada volcanics) are exposed continuously along the northern (Mount Bennett Hills or MBH) and southern margins of the west-central Snake River Plain ...
Structural evolution of the central External Betic Cordillera, southern Spain
A new tectonic subdivision of the central External Betic Cordillera is proposed based on previous stratigraphic studies, interpretation of seismic reflection profiles and balanced cross-sections. All available surface and ...
