SITE SUMMARIESSite: 1040R
Objectives: The objectives of Site 1040R are to:
1. Investigate the décollement.
2. Investigate fluid flow within the décollement and underthrust sediments.
3.Install modified CORKs to monitor pressure and temperature and to sample fluids within the décollement and underthrust sediments.
Drilling Program: Three adjacent holes will be drilled at Site 1040R. The first will be cored with the RCB from 180 to 410 mbsf and then a modified CORK will be installed for monitoring fluid flow, pressure, and temperature in the uppermost underthrust sediments (~425 mbsf). The next two holes will be drilled (likely without coring) and a modified CORK will be installed in each hole for monitoring fluid flow, pressure, and temperature in the décollement.
Logging and Downhole: Formation temperature measurements (~5 DVTP); no downhole logging is planned at this site.
Nature of Rock Anticipated: Deformed claystones and hemipelagics.
