• Location map (Fig. F2)
Objective: Alternate for Site CRIS-2B. Penetration of décollement at shallow level, fluid flow regime, oceanic crust.
Drilling and logging program: • APC to refusal, then XCB to 500 mbsf.
• RCB from 490 to 980 mbsf.
• Conduct wireline logging or LWD/LWC.
Nature of rock anticipated: Sediments: mud and silt, mud-supported breccia, and basaltic flows
