Late Miocene Origin of the Benguela Upswelling System off Northern Namibia
TLDR
Deep Sea Drilling Project cores collected at site 362/362A suggest the time of initiation of the Benguela upwelling system off northern Namibia began in the early late Miocene, about 10 million years before the present.
Tertiary Sea-Level Movements around Southern Africa
Sedimentological, micropaleontological and seismic-profiling data elucidate the history of Tertiary sea-level movements around southern Africa. These new data show that landward movement of the sea
13. PLEISTOCENE CALCAREOUS NANNOFOSSIL BIOSTRATIGRAPHY AND THE WESTERN MEDITERRANEAN SAPROPELS, SITES 974 TO 977 AND 979 1
During Ocean Drilling Program Leg 161, six sites were drilled in the western Mediterranean. Pleistocene sediments were cored at Sites 974, 975, 976, 977, and 979. Occurrences of generally very
Cenozoic Calcareous Nannofossil Biostratigraphy on the Exmouth Plateau, Eastern Indian Ocean
Six sites (759-764) were drilled on the Exmouth Plateau during Ocean Drilling Program Leg 122. Nannofossilrich Cenozoic sediments were recovered at all six sites, reflecting the open-ocean conditions
Paleoproductivity of the Indian Ocean during the Tertiary Period
Abstract Studies of oceanic paleoproductivity have lagged in part because of the absence of a suitable proxy for measuring paleoproductivity. A transfer function has recently been proposed which
Cretaceous Calcareous Nannofossil Biostratigraphy of Sites 761, 762, and 763, Exmouth and Wombat Plateaus, Northwest Australia
Three sites drilled during Leg 122, Site 761 on the Wombat Plateau and Sites 762 and 763 on the Exmouth Plateau, provide a composite Cretaceous section ranging in age from Berriasian to
Relict and Recent Beachrock from Southern Africa
Beachrock forms a broken pavement along part of the southwestern coast of South Africa. The rocks are found in the intertidal zone as well as slightly above high-tide and below low-tide level. The
Calcareous Nannofossil Genus Scyphosphaera: Structure, Taxonomy, Biostratigraphy, and Phylogeny
TLDR
Fifty-three species and one variety have been assigned to this genus since 1902, yet the genus remains one for which many nannofossil workers make only a cursory attempt to list the species present in an assemblage.
Authigenic pyrite and gypsum in South West African continental slope sediments
An unusual association of authigenic pyrite and authigenic gypsum has been found in silty clays recovered from the South West African continental slope. Nannofossil content suggests that the
