Figure F46. Polyphased extensional faulting in Subdomain IIa (interval 180-1118A-40R-4, 40-103 cm [583.76 mbsf]). A. Core observations: B = bedding orientation and dip; F = fault orientation and dip. B. Sketch showing (1) the successive strata rotations in the hanging wall of the west-dipping fault network, and (2) the timing relationships between faults Fe and Fw. (Orientation in core reference frame) Fe = fault facing to the east; Fw = fault facing to the west.
