Pleistocene-Pliocene strontium-isotope ratios of ODP Site 107-653 (Table 1)

Strontium isotopic determinations were made on samples from the Pliocene-Pleistocene sequence recovered at ODP Hole 653A, the proposed "deep-sea type section" for the Mediterranean region. Biostratigraphic correlations can be combined with the patterns of variations in the 87Sr/86Sr values to delineate the following: (1) the earliest Pliocene (MP11 to basal MP12 zones) is distinguished by fluctuations in the ratio, probably related to the unstable paleoceanographic conditions following the Zanclean flooding and initial in-filling of the Mediterranean after the Messinian desiccation, (2) during most of the Pliocene between approximately 4.5 and 2.4 Ma (MP12 to MP15 zones) the 87Sr/86Sr values remain relatively constant, producing a plateau in the strontium isotope-depth curve for this period, and (3) beginning at approximately 2.4 Ma (across the MP15/MP16 boundary) and continuing into the latest Pleistocene, the 7Sr/86Sr values increase significantly but show fluctuations that have both positive and negative slopes. The presence of a plateau in the curve generated for the Mediterranean type section duplicates in greater detail the late Neogene results reported by DePaolo (1986, doi:10.1130/0091-7613(1986)14<103:DROTNS>2.0.CO;2). The virtual lack of change in the ratio between 4.5 and 2.4 Ma essentially eliminates strontium isotopes as a high-resolution correlation method for this period. The fluctuations in the ratio beginning at 2.4 Ma may be a reflection of major climatic changes occurring in the latest Pliocene-Pleistocene. The relationship between glacial-interglacial cycles and seawater 87Sr/86Sr values suggested by DePaolo (1986) and Capo and DePaolo (1987) is uncertain but should be tested as significant increases and decreases in 87Sr/86Sr of seawater have apparently occurred since 2.4 Ma.

Event no. 656

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. One of nine interesting events from the IMB detector in its first 204 live days of running. Similar to proton decay but rejected.
