Objective (see text for details):
|
Sample Marshall Paraconformity and top of Amuri Limestone (late Eocene to early Oligocene)
Sample distal facies of sequences. Identified at this site are Unconformities U13, U11, U9, and U7 (late Miocene to late Pliocene).

Drilling, coring, and downhole measurement program:
|
Hole A
• APC/XCB to refusal (APC core orientation)
Hole B
• Drill without coring to APC refusal depth
• RCB coring to 1106 mbsf
• Wireline log (triple combo, FMS-sonic)
• VSP with VSI
|
Anticipated lithology:
|
0–871 mbsf: Terrigenous siltstone and silty mudstone with intervals of fine-grained sand and mud
871 mbsf (or slightly shallower)–1106 mbsf: Limestone
