Paleogene Benthic Foraminifers from the Southern Indian Ocean (Kerguelen Plateau): Biostratigraphy and Paleoecology

Abstract: Benthic foraminifers were studied from lower Paleocene through upper Oligocene sections from Sites 747 and 748. The composition of the benthic foraminifer species suggests a middle to lower bathyal (600-2000 m) paleodepth during the Neogene and a probable upper abyssal (2000-3000 m) paleodepth during the Paleocene at Site 747. Site 748 is thought to have remained at middle to lower bathyal paleodepths throughout the Cenozoic. Principal component analysis distinguished four major benthic foraminifer assemblages… Show more

“…Additionally, the shallower depth of the Kerguelen Plateau in our Miocene bathymetry steers the sub‐Antarctic front poleward, (Figure 2). The depth of the Kerguelen Plateau in our Miocene bathymetry is ∼1,000 m, consistent with paleodepth constraints from benthic foraminifera [ Mackensen and Berggren , 1992]. To our knowledge the effect of Large Igneous Provinces on poleward heat transport has not been examined and should be the focus of future studies.…”

“…The preferred species was C. praemundulus , but a degree of variability outside the strict definition of the species was allowed. Other Cibicidoides taxa that are less common in Site 738 and 748 sediments, such as C. bradyi , C. eocaenus , C. laurisae , C. micrus , and C. subspiratus [see Mackensen and Berggren , 1992], were avoided and not used for stable isotope analysis in this study. Identification of these taxa was aided by the descriptions and illustrations given by van Morkhoven et al [1986].…”

“…Such a verification was carried out here using Deep Sea Drilling Project and Ocean Drilling Project records. Based on these records the depth of the Madagascar Ridge (Schlich, 1974), Mascarene Ridge (Backman et al, 1988;Fisher et al, 1974;, Shatsky Rise, Ontong Java Plateau (Barrera et al, 1993), Kerguelen Plateau (Mackensen and Berggren, 1992), Walvis Ridge (Zachos et al, 2005;Fuetterer, 1984) and the Rio Grande Rise (Perch-Nielsen et al, 1977) were adjusted.…”
