Multichannel seismic reflection profiles of the continental crust beneath the Newfoundland Ridge

Abstract

Multichannel seismic reflection profiles extending south from the Grand Banks indicate that large ‘basement’ features underlying the Newfoundland Ridge are composed of sedimentary strata. The Newfoundland Ridge, therefore, is interpreted as an area of subsided continental crust rather than a ridge of oceanic crust. The J magnetic anomaly intersects this complex, and the physiographic ridge associated with this anomaly may also be continental in origin.
