| contents | DSDP Leg 337 was planned as an attemp at deep penetration of the igneous section of the oceanic crust on the western flank of the FAMOUS (Franco- American Mid-Ocean Undersea Study) area of the Mid-Atlantic Ridge at 36°N. Site 332 is located in Deep Drill Valley approximately 30 km west of the axis of the Mid-Atlantic Ridge at 36°52'N latitude. The principal goal at this site was deep penetration into layer 2 of the ocean crust by multiple re-entry. Site 334 was drilled on a steep east-facing slope in a small, deep basin near the middle of magnetic anomaly 5. In this area, breccias with gabbro and peridotite clasts in a nannofossil-foram ooze matrix are interlayered with the plutonic rocks and may reflect exposure of a melange in or near the Median Valley of the Mid- Atlantic Ridge prior to burial by later basaltic extrusions. |
