profiling of the continental margin: Grand

Summary. The 1985 Lithoprobe East profiles resolve deep crustal structure of the Grand Banks off eastern Canada. Basins are 7 to 20 km deep, and bounded by major faults traceable to Moho depth. The lower crust is reflective along much of the survey, and the top of this reflective layer has a variable depth. Prominent and often surprisingly flat Moho reflections are observed, Puzzling rotated fault blocks are imaged at the continent-ocean transition. 1
