Geology and stratigraphy of forearc
basin sediments in Hokkaido, Japan: Cretaceous environmental events on the north-west Pacific margin.
(2009) used GPS velocities to investigate the motion of the region between an oceanic trench and its associated volcanic arc (forearc
), regions that are found at convergent margins.
Ingersoll, R.V (1983): Petrofacies and provenance of late Mesozoic forearc
basin, northern and central California.
The studies provide new data from the upper mantle to the surface, from the forearc
to the active foreland basin, and employ a wide array of techniques and methods in geophysics, petrology, geochronology and thermochronology, sedimentology, structural geology, geomorphology, paleoaltimetry, and geodynamic modeling.
Geophysical evidence suggests extension of the JFR beyond the trench (e.g., Papudo seamount; Von Huene et al, 1997; Yanez et al, 2001) with related forearc
deformation and intraplate seismicity (Von Huene et al, 1997; Yanez et al, 2002).
The highest density of volcanoes in arc settings occurs along the volcanic front; the boundary between the volcanic arc and the non-volcanic forearc
