• 3-D InLine 2645 (Fig. AF31, AF32)
• 3-D CrossLine 6980 (Fig. AF33)
Objective
(see text for full details):
Total history of the splay fault system is depicted by integrating the results from proposed Site NT3-01 as a reference for this site.
Drilling, coring, and downhole measurement program:
See NT3-01B
Anticipated lithology:
0–1039 mbsf: slope basin sediments; rapidly deposited sand/silts/clays
~420 mbsf: bottom-simulating reflector
1039–1400 mbsf: older accreted prism
