1. Leg 209 Summary: Processes in a 20-km-thick Conductive Boundary Layer beneath the Mid-atlantic Ridge, 14°–16°n
This paper provides a summary of postcruise scientific results from Ocean Drilling Program (ODP) Leg 209 available to date, building upon shipboard observations and syntheses summarized in the Leg 209 Initial Results volume. During Leg 209, 19 holes were drilled at 8 sites along the Mid-Atlantic Ridge from 14°43′ to 15°44′N, mainly in residual mantle peridotite intruded by gabbroic rocks, in or...
متن کاملDrilling Program: SHIPBOARD SCIENTIFIC PARTY
The bend in the Hawaiian-Emperor chain is the best example of a change in plate motion recorded in a fixed-hotspot frame of reference. Alternatively, the bend might primarily record differences in motion of the Hawaiian hotspot relative to the Pacific lithosphere. Four lines of inquiry support the latter view: (1) global plate motions predicted from relative plate motion data, (2) spreading rat...
متن کامل5. Explanatory Notes
Information assembled in this chapter will help the reader understand the basis for our preliminary conclusions and will also enable the interested investigator to select samples for further analysis. This information concerns only shipboard operations and analyses described in the site reports in the Leg 201 Proceedings of the Ocean Drilling Program, Initial Reports volume. Methods used by var...
متن کامل18. Constraints on the Geometry and Fracturing of Hole 894g, Hess Deep, from Formation Microscanner Logging Data
Ocean Drilling Program Hole 894G, sited on a small horst within Hess Deep, was drilled in lower oceanic crust that was generated at the East Pacific Rise and then rifted by the propagating Cocos/Nazca divergent plate boundary. Difficult drilling conditions in fractured gabbros resulted in a washed-out hole. Despite these unfavorable circumstances, open-hole logs from the Formation MicroScanner ...
متن کاملReal-time drilling mud gas monitoring for qualitative evaluation of hydrocarbon gas composition during deep sea drilling in the Nankai Trough Kumano Basin
BACKGROUND Integrated Ocean Drilling Program Expedition 338 was the second scientific expedition with D/V Chikyu during which riser drilling was conducted as part of the Nankai Trough Seismogenic Zone Experiment. Riser drilling enabled sampling and real-time monitoring of drilling mud gas with an onboard scientific drilling mud gas monitoring system ("SciGas"). A second, independent system was ...
