(eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office) 74 https://doi.org/10.2973/dsdp.proc.74.116.1984 613-619 Carbon and oxygen isotope measurements were made in bulk sediments from the five sites drilled on Leg 74, covering much of the Cenozoic. These stable carbon isotope analyses document a lightening across the Cretaceous/Tertiary boundary (already documented by other workers), with a minimum about 0.2 Ma after the boundary; a trend to very heavy values in the late Paleocene; a lightening near the Paleocene/Eocene boundary to a second minimum early in the early Eocene; more positive values in the remainder of the Eocene with a minor peak immediately below the Eocene/Oligocene boundary, at which there is a lightening trend; a moderately positive peak in the middle Miocene, and a lightening toward the present, where the isotopically lightest values in the Cenozoic are to be found. The carbon isotope variations observed are largely a function of changes in the 13C content of oceanic dissolved inorganic carbon that resulted from alterations in the global carbon budget. Slight differences among sediments of the same age at different sites probably result from diagenetic changes, but do not obscure the major pattern, which has considerable potential value for stratigraphic correlation. 1.7633 2.9853 -29.0707 -28.0415 2.56518 -28.727639999999997 1980-06-10T00:00:00 1980-07-18T00:00:00 0.1 475.86 not specified DSDP Deep Sea Drilling Project http://www.deepseadrilling.org/ Deep Sea Drilling Project DSDP 74-525 -29.0707 2.9853 South Atlantic/CREST -2467.0 1980-06-10T00:00:00 Leg74 Leg74 1980-06-09T00:00:00 1980-06-09 1980-07-21T00:00:00 1980-07-21 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Rabinowitz, Philip D Rabinowitz, Philip D doi:10.2973/dsdp.proc.74.1984 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 3.6 m 3.6 m 1 cores; 3.6 m cored; 0 m drilled; 99.7 % recovery 74-525A -29.0707 2.9853 South Atlantic/CREST -2467.0 1980-06-10T00:00:00 Leg74 Leg74 1980-06-09T00:00:00 1980-06-09 1980-07-21T00:00:00 1980-07-21 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Rabinowitz, Philip D Rabinowitz, Philip D doi:10.2973/dsdp.proc.74.1984 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 678.1 m 406.6 m 62 cores; 549.7 m cored; 6 m drilled; 74 % recovery 74-527 -28.0415 1.7633 South Atlantic Ocean -4428.0 1980-06-28T00:00:00 Leg74 Leg74 1980-06-09T00:00:00 1980-06-09 1980-07-21T00:00:00 1980-07-21 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Rabinowitz, Philip D Rabinowitz, Philip D doi:10.2973/dsdp.proc.74.1984 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 384.5 m 243.4 m 43 cores; 380 m cored; 4.5 m drilled; 64.1 % recovery 74-528 -28.5248 2.324 South Atlantic/RIDGE -3800.0 1980-07-04T00:00:00 Leg74 Leg74 1980-06-09T00:00:00 1980-06-09 1980-07-21T00:00:00 1980-07-21 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Rabinowitz, Philip D Rabinowitz, Philip D doi:10.2973/dsdp.proc.74.1984 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 555 m 271.9 m 47 cores; 441 m cored; 0 m drilled; 61.7 % recovery 74-529 -28.9305 2.768 South Atlantic/SLOPE -3043.0 1980-07-18T00:00:00 Leg74 Leg74 1980-06-09T00:00:00 1980-06-09 1980-07-21T00:00:00 1980-07-21 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Rabinowitz, Philip D Rabinowitz, Philip D doi:10.2973/dsdp.proc.74.1984 Glomar Challenger https://www-odp.tamu.edu:443/glomar.html Drilling/drill rig DRILL 417 m 309.4 m 42 cores; 398 m cored; 19 m drilled; 77.7 % recovery 1140 CC-BY-3.0 Creative Commons Attribution 3.0 Unported https://creativecommons.org/licenses/by/3.0/ Sediment depth is given in mbsf.
