RECORD BASALT RECOVERY- Robert L. Fisher, Research Geologist at Scripps Institution of Oceanography, holds a section of fresh basalt breccia, a volcanic rock cored from 80.5 meters into the igneous basement that underlies more than 500 meters of deep-sea sediment in the central Indian Ocean. His cruise Co-Chief Scientist on Leg 24 of the Deep Sea Drilling Project, Elizabeth T. Bunce, left, associate scientist at Woods Hole Oceanographic Institution, Mass., stands behind the tungsten carbide insert roller cone bit that made the record hard-rock penetration aboard D/V Glomar Challenger in June 1972. This basaltic core consists of glass with minor inclusions of white carbonate sediment, and is of Lower Oligocene age -- about 30 million years old. June 1972
