Rifting of a passive margin and development of a lower-crustal detachment zone: Evidence from marine magnetotellurics

Heinson, Graham; White, A.; Lilley, F. E. M.


Rifting of passive margins has, in some places, led to the development of extensive submerged continental platforms. Crustal thinning by a factor of two or more is at least partially accommodated by high-angle normal faults that extend through the brittle upper crust to the ductile parts of the lower crust. However, an approximately horizontal detachment zone has been postulated to explain the width of the shelf and differences between the amounts of upper crust and lower lithosphere extension....[Show more]
