Campanian-Maestrichtian benthic foraminifera of DSDP Hole 78-543A
Foraminiferal assemblages in sediments from Hole 543A suggest that toward the end of the Cretaceous there was an oscillating carbonate compensation depth (CCD) in the western... -
Foraminiferal species and dissolution index at DSDP Hole 78-541
The calcite compensation depth (CCD) fluctuates as a result of changes in the water-mass system, thereby producing a distinct dissolution pattern. Differential dissolution... -
Geochemistry and trace elements at DSDP Hole 78-543A
The upper part of the basaltic substratum of the Atlantic abyssal plain, approaching subduction beneath the Barbados Ridge and thus presumably beneath the Lesser Antilles island... -
Major-oxides and trace-elements at DSDP Hole 78-543A
Four chemically distinct basalts were cored in 44 m of basement penetration at Deep Sea Drilling Project Site 543, in Upper Cretaceous crust just seaward of the deformation... -
Geochemistry and Nd-Pb isotope ratios of sediments from the Lesser Antilles arc
The Lesser Antilles arc is a particularly interesting island arc because it is presently very active, it is located perpendicular to the South American continent and its... -
Magnetic properties of Cenozoic MORB and Cretaceous MORB from DSDP and ODP holes
The fact that the natural remanent magnetization (NRM) intensity of mid-oceanic-ridge basalt (MORB) samples shows systematic variations as a function of age has long been... -
Geochemistry of the oldest Atlantic oceanic crust
Controversy has surrounded the issue of whether mantle plume activity was responsible for Pangaean continental rifting and massive flood volcanism (resulting in the Central... -
Element contents and isotope composition of sediments and basalts from DSDP S...
Twenty-four piston core sediment samples and 13 sediments and 3 basalts from DSDP Leg 78 Site 543 were analyzed for Sr, Nd and Pb isotopic compositions. The results show... -
Trace element concentrations and Li isotope composition in DSDP and ODP sedim...
We have studied the sedimentary and basaltic inputs of lithium to subduction zones. Various sediments from DSDP and ODP drill cores in front of the Mariana, South Sandwich,...
