Nitrogen isotopes of bulk sediments for OAE2 samples
Sediment records of the stable isotopic composition of N (d15N) show light d15N values at several sites in the proto-North Atlantic during Oceanic Anoxic Event 2 (OAE 2) at the... -
Organic geochemistry of Cretaceous black shales from the Galicia Margin
Organic-carbon-rich "black shales" from three different Cretaceous episodes sampled during Ocean Drilling Program Leg 103 have been studied by organic geochemical methods.... -
Interstitial water chemistry of ODP Leg 103 sites
Interstitial waters were squeezed from strata recovered at Sites 637-641 of ODP Leg 103 on the Galicia margin, along the northwestern Iberian continental margin in the northeast... -
Characteristic magnetizations of paleomagnetic samples from ODP Leg 103
Lower Cretaceous and Tithonian sediments were sampled for magnetostratigraphy at six holes (Holes 638B, 638C, 639A, 639D, 640A, and 641C). Magnetic polarity chrons were assigned... -
Cenozoic sediments facies and geochemistry of ODP Hole 103-637A
The late Cenozoic deposits recovered at ODP Site 637 from the Iberian Abyssal Plain near the continental margin off northwestern Spain include three main facies groups.... -
Organofacies reconstruction and lipid geochemistry of sediments from the Gali...
Samples of Lower to middle Cretaceous rocks from ODP Sites 638, 640, and 641, drilled on the Galicia continental margin in the northeast Atlantic, have been investigated by... -
Organic geochemistry of Cretaceous black shales
Organic-carbon-rich 'black shales' and adjacent organic-carbon-poor rocks from three different Cretaceous settings encountered during ODP Leg 103 have been studied by organic... -
Macroturbidites of ODP Hole 103-641C
Barremian through uppermost Aptian strata from ODP Hole 641C, located upslope of a tilted fault block on the Galicia margin (northwest Spain), are syn-rift sediments deposited... -
Composition of Lower Cretaceous sandstones of the Galicia margin
The composition of 31 samples of Lower Cretaceous (Valanginian to Aptian) sandstone from ODP Sites 638 through 641 was analyzed using the Gazzi-Dickinson point-counting method.... -
Cretaceous-Tertiary ichthyoliths of brown clay intervals
The pattern of ichthyolith distribution established in sequences with stratigraphies based on calcareous or siliceous microfossils is used to provide age correlations for three... -
Calcareous nannofossils of ODP Leg 103 holes
Ocean Drilling Program Leg 103 occupied five sites on the Galicia margin, northwest of the Iberian Peninsula. Two holes (Holes 637A and 638B) yielded significant Cenozoic... -
Chemistry of orthopyroxenes, clinopyroxenes, and spinels of ODP Hole 103-637A...
Mineral compositions of the plagioclase-bearing ultramafic tectonites dredged and cored seaward of the continental slope of the Galicia margin (Leg 103, Site 637) were compared... -
Chemistry of minerals of ODP Hole 103-637A peridotites
The Galicia margin lies northwest of the Iberian Peninsula and is a passive ocean margin with thin sedimentary cover. Altered peridotite was recovered from ODP Site 637, on the... -
Calcite composition and stable isotope record of ODP Hole 103-637A peridotites
The peridotite recovered from Ocean Drilling Program Hole 637A, Galicia margin, has suffered extensive low-temperature alteration that includes serpentinization, calcite... -
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...
