Aeromagnetic evidence for a buried Early Cretaceous magmatic arc, northeast Japan Aeromagnetic evidence for a buried Early Cretaceous magmatic arc, northeast Japan
Positive aeromagnetic anomalies, recent drilling, and models constructed from these data delineate the plutonic roots of the Early Cretaceous Kitakami magmatic arc in northeast Japan. Buried plutons, mostly offshore, produce belts of positive magnetic anomalies. These anomalies and magnetotelluric data suggest that the plutons form a batholith 70–120 km wide, nearly 800 km long, and 10...

CASERTZ aeromagnetic data reveal late Cenozoic flood basalts(?) in the West Antarctic rift system CASERTZ aeromagnetic data reveal late Cenozoic flood basalts(?) in the West Antarctic rift system
The late Cenozoic volcanic and tectonic activity of the enigmatic West Antarctic rift system, the least understood of the great active continental rifts, has been suggested to be plume driven. In 1991-1992, as part of the CASERTZ (Corridor Aerogeophysics of the Southeast Ross Transect Zone) program, an ∼25000 km aeromagnetic survey over the ice-covered Byrd subglacial basin shows...

Magnetic and gravity constraints on forearc upper crustal structure and composition, offshore northeast Japan Magnetic and gravity constraints on forearc upper crustal structure and composition, offshore northeast Japan
Marine magnetic and gravity data from the northeast Japan forearc offer insight to the subsurface structure, density and magnetization from which geologic interpretations and tectonic reconstructions can be made. Positive marine magnetic anomalies, on-land geology, drill hole data, and 2-1/2-dimensional models reveal that Kitakami plutons and possibly their associated volcanic rocks...

Active volcanism beneath the West Antarctic ice sheet and implications for ice-sheet stability Active volcanism beneath the West Antarctic ice sheet and implications for ice-sheet stability
IT is widely understood that the collapse of the West Antarctic ice sheet (WAIS) would cause a global sea level rise of 6 m, yet there continues to be considerable debate about the detailed response of this ice sheet to climate change1-3. Because its bed is grounded well below sea level, the stability of the WAIS may depend on geologically controlled conditions at the base which are...
