Abstract:

Site 634, drilled during ODP Leg 101, was essentially a reoccupation of Site 98, drilled during DSDP Leg 11 (Hollister, Ewing, et al., 1972, doi:10.2973/dsdp.proc.11.1972; Table 1, Fig. 1). At Site 634, the upper 144 m of sediment was washed in an attempt to reach the Upper Cretaceous target horizon in the time remaining for the cruise (Austin, Schlager, et al., 1986, doi:10.2973/odp.proc.ir.101.1986). Figure 2 illustrates the spatial relationship of Site 98 (2750 m water depth) and Site 634 (2835 m water depth), 0.2 nmi to the northwest. Radiolarians were observed in Site 98 samples from 100 to 240 meters below seafloor (mbsf) during Leg 11, but no detailed biostratigraphic analyses were conducted. Thus, Site 98 presented us an opportunity to sample material correlating with the washed section at Site 634. Samples were taken from Cores 101-634A-2R through 101-634A-4R to study radiolarians, but all proved barren, nor were radiolarians observed in shipboard smear slides. A correlation between Sites 98 and 634 (Fig. 2) suggests that these cores represent the same interval as that recovered in Cores 11-98-10 and 11-98-11, which were also barren. These results are presented separately from other Leg 101 radiolarian studies (Palmer, 1988, datasets: doi:10.1594/PANGAEA.743055) because the Site 98 fauna was predominantly Eocene, while other radiolarian assemblages studied were Oligocene and Miocene.
