Initial Reports of the Deep Sea Drilling Project - Volume 23

This volume covers Leg 23 of the cruises of the Drilling Vessel Glomar Challenger. The twenty-third cruise of the drilling vessel Glomar Challenger, under contract to the JOIDES Deep Sea Drilling Project, lasted from 8 March to 1 May 1972. The cruise began at Colombo, Sri Lanka (formerly Ceylon) and ended at Djibouti in the French Territory of the Afars and Issas. A total of 12 drill sites was occupied, six each in the Arabian Sea and the Red Sea. At all sites there was an obvious interest in reconstructing the stratigraphic record both from a sedimentological and paleontological viewpoint. An objective of all the sites was also to sample and date one or more reflectors and to relate these to the regional stratigraphy.
