Geochemistry and stable isotopes of peridotites of ODP Hole 103-637A
A ridge of strongly serpentinized, plagioclase-bearing peridotite crops out at the boundary between the Atlantic oceanic crust and the Galicia continental margin (western... -
Chemistry of peridotites of ODP Hole 103-637A
A ridge of peridotite was drilled off of the Galicia margin (Hole 637A) during ODP Leg 103. The ridge is located at the approximate boundary between oceanic and continental... -
Cretaceous calcareous nannofossils of ODP Leg 103 holes
Ocean Drilling Program Leg 103 recovered Lower Cretaceous sediments from the Galicia margin off the coast of Iberia. The high diversity and abundance of assemblages makes this... -
Characterization of diagenetic fluids at ODP Site 103-639
Site 639, drilled during Leg 103 of the Ocean Drilling Program, penetrated an Upper Jurassic to Lower Cretaceous carbonate platform on a tilted fault block along the Galicia... -
Stable carbon and oxygen isotope ratios of carbonates of ODP Site 103-639
A Tithonian sequence of shallow-water limestones, intercalated with siliciclastics and overlain by dolomite, was recovered during drilling at ODP Site 639 on the edge of a... -
Chemical composition of rhyolites of ODP Site 103-639
Holes 639E and 639F were drilled along the western slope of a tilted fault block in an attempt to recover complete syn- and pre-rift stratigraphic sections and continental... -
The Cenomanian/Turronian Boundary Event at ODP Hole 103-641A
Drilling at ODP Site 641 (on the western margin of Galicia Bank, off northwestern Spain) revealed a thin, but pronounced, interval of black shale and gray-green claystone. Our... -
Cretaceous dinoflagellate cysts of ODP Leg 103 holes
The dinoflagellate cyst assemblages in 42 samples collected from Sites 638 and 639 were analyzed. All samples from Site 639 are barren; relatively poor assemblages occur in... -
Early Cretaceous spores and pollen of ODP Leg 103 holes
About 80 species of spores and pollen grains were recorded during detailed palynological investigations of selected Lower Cretaceous sections from Holes 638B and 638C and the... -
Cretaceous radiolarians of the North Atlantic Ocean
Radiolarians form a remarkable part of the fossil plankton for Cretaceous sediments of the North Atlantic. Selected sites with long-term sedimentary successions of deep facies... -
Agglutinated benthic foraminifera of the Upper Cretaceous
A reexamination of the agglutinated benthic foraminiferal microfaunas found in the Upper Cretaceous red and brown clays of DSDP Hole 603B and ODP Holes 640A and 641A allows us... -
Geochemistry of the oceanic crust from ocean drilling samples
This book presents new data on chemical and mineral compositions and on density of altered and fresh igneous rocks from key DSDP and ODP holes drilled on the following main... -
Depth, age, strontium isotopic ratios and trace elemental ratios of samples f...
Large variations exist between published mid-Cretaceous (late Barremian to early Turonian stages) seawater Sr-isotope stratigraphies; this has resulted in disparate... -
Dinoflagellate cysts of the Early Cretaceous North Atlantic Ocean
Early Cretaceous dinoflagellate cysts were reinvestigated from nine deep-sea sites of the North and Central Atlantic. In general the zonation scheme developed for the western... -
Diversity of abyssal agglutinated foraminifera from Cenomanian to Santonian s...
Benthic foraminiferal assemblages of distinctive taxonomic composition occur at the top of benthic fossil-free black shales which correspond to the anoxic event at the...
