Geophysical observations bearing upon the origin of the newfoundland ridge |
|
| Authors: | AC Grant |
| Abstract: | Multichannel reflection seismic profiles extending southward from the Grand Banks show gently dipping reflectors within “basement” features underlying the Newfoundland Ridge. These reflections appear to be from sedimentary strata, indicating that the Newfoundland Ridge is a remnant of a former sedimentary basin, rather than a ridge of oceanic crust as prescribed by plate tectonic models. Probably this feature is underlain, and to some extent surrounded by, continental crust. |
