(Table 2) Organic residue at DSDP Hole 76-534A
The kind, sedimentation rate, and diagenesis of organic particles delivered to the North Atlantic seafloor during the Middle Jurassic-Early Cretaceous were responsible for the... -
(Appendix) Characteristic directions at DSDP Hole 76-534A
Kimmeridgian-Tithonian red marly limestones and Berriasian white limestones were recovered at Site 534 of DSDP Leg 76 in the western North Atlantic. These yielded a well-defined... -
(Table 2) Physical properties at DSDP Holes 44-391 and 76-534
Laboratory measurements on sediment samples and density well logs run at DSDP Site 534 in the Blake-Bahama Basin were used to establish an in situ velocity and density... -
(Table 1) Interstitial water chemistry at DSDP Leg 76 Holes
Low salinities and strong opposing fluctuations between chlorinity and interstitial water d18O and dD characterize the region of gas-hydrate occurrence at Site 533. In addition... -
