Chemical composition of bottom sediments and rocks from DSDP Holes 3-14 throu...
Data on analyses of chemical composition of DSDP samples of bottom sediments and rocks carried out in P.P. Shirshov Institute of Oceanology are reported. Basal sediments and... -
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... -

(Table 3) Isotope ratios of Sr, Nd and Ce and LREE concentrations in Pacific ...
Isotope ratios of Ce, Nd and Sr, and light rare-earth elements (La, Ce, Nd and Sm) concentrations were measured for sixteen N-type MORB samples from DSDP Sites 420, 421, 429,... -
Mean element and biogenic silica concentrations in Arctic Ocean sediments (Ta...
Quantitative determination of biogenic silica in Late Cretaceous and Paleogene deep-sea sediment cores from the central Arctic Ocean provides evidence of open-ocean polar... -
Analysis of Mn-deposits recovered during Leg 54
Two distinct sedimentary facies produced by sea-floor hydrothermal activity were cored during Deep Sea Drilling Project Leg 54. The first is equivalent to the typical basal... -
Velocity-density systematics for basalts at DSPD Leg 54 Holes
Precise velocity and density measurements at atmospheric and elevated pressures have been obtained on basalts drilled in 13 holes during Leg 54. The vp-sigma data show... -
Silicate mineralogy of basalts at DSDP Leg 54 Holes
Basalts drilled from the East Pacific Rise, OCP Ridge, and Siqueiros fracture zone during Leg 54 are texturally diverse. Dolerites are equigranular at Sites 422 and 428 and... -
Composition and origin of sediments at DSDP Site 54-424
The sediments recovered on Deep Sea Drilling Project Leg 54 appear to be mixtures of the normal pelagic sediments of the area and hydrothermally produced manganese and iron... -
Sedimentology, mineralogy, and geochemistry of hydrothermal deposits at DSDP ...
On Leg 54 of the Deep Sea Drilling Project, four holes were drilled at Site 424, about 20 km south of the Galapagos Spreading Center (GSC). The holes were situated less than 300... -
Minerals, geochemistry and x-ray power characteristics at DSDP Sites 54-424, ...
Secondary minerals filling veins and vesicles in volcanic basement at Deep Sea Drilling Project Sites 458 and 459 indicate that there were two stages of alteration at each site:... -
Radiochemistry at DSDP Leg 54 and 70 Holes
Use of the hydraulic piston corer during DSDP Leg 70 in the Galapagos mounds area allowed recovery of an undisturbed sedimentary sequence down to the basement. It thus became... -
Geochemistry of Loihi Seamount hydrothermal deposits
High-resolution bathymetric surveys, bottom photography and sample analyses show that Loihi Seamount at the southernmost extent of the Hawaiian ëhotspotí is an active, young... -
Marine barite in sediments of DSDP Site 54-424
The distribution of barite in sediments from D.S.D.P. sites 424 and 424A at the Galapagos hydrothermal mounds field is determined and the process of its formation is deduced.... -
Composition of sediments and cores from DSDP Legs 54 and 61-63
The monograph gives results of studies of sediments and rocks collected from D/S Glomar Challenger in the Pacific Ocean. These studies have been based on the lithological facial... -
