    Description: The western part of the North Atlantic Ocean holds clues to some of the most intriguing questions in marine geology. But because the geologic problems are many and varied, the sites of Leg 44 were multipurpose in nature. In particular, some of the targets were : 1) the Blake Nose, a spur of the Blake Plateau, to determine the nature, age, and origin of reef-like structures recognized on seismic profiles and 2) the Blake Outer Ridge, a long low ridge of sediments that forms the eastern boundary of the Blake-Bahama Basin, where we hoped to study the stratigraphy and sample supposed clathrates.

    Description: During METEOR Cruise 34/2 the recovered gravity cores were subject to laboratory geophysical studies. A routine shipboard measurement of three physical parameters was carried out on the segmented sediment cores, comprising the determination of - the compressional (P-) wave velocity vp, - the electric resistivity Rs, and - the magnetic volume susceptibility K. These properties are closely related to the grain size, porosity and Iithology of the sediments and provide high-resolution core logs (spacing 2 cm) available prior to all other detailed investigations. In addition, oriented samples for later shore based paleo- and rock magnetic studies were taken at intervals of 10 cm.

In addition, oriented sampies for later shore based paleo- and rockmagnetic studies were taken at intervals of 10 cm.

    In:  Supplement to: Nähr, Thomas H; Botz, Reiner; Bohrmann, Gerhard; Schmidt, Mark (1998): Oxygen isotopic composition of low-temperature authigenic clinoptilolite. Earth and Planetary Science Letters, 160(3-4), 369-381, https://doi.org/10.1016/S0012-821X(98)00097-1
    Publication Date: 2024-01-09
    Description: Oxygen isotope ratios were obtained from authigenic clinoptilolites from Barbados Accretionary Complex, Yamato Basin, and Exmouth Plateau sediments (ODP Sites 672, 797, and 762) in order to investigate the isotopic fractionation between clinoptilolite and pore water at early diagenetic stages and low temperatures. Dehydrated clinoptilolites display isotopic ratios for the zeolite framework (delta 18Of) that extend from +18.7 per mil to +32.8 per mil (vs. SMOW). In combination with associated pore water isotope data, the oxygen isotopic fractionation between clinoptilolite and pore fluids could be assessed in the temperature range from 25ºC to 40ºC. The resulting fractionation factors of 1.032 at 25ºC and 1.027 at 40ºC are in good agreement with the theoretically determined oxygen isotope fractionation between clinoptilolite and water. Calculations of isotopic temperatures illustrate that clinoptilolite formation occurred at relatively low temperatures of 17ºC to 29ºC in Barbados Ridge sediments and at 33ºC to 62ºC in the Yamato Basin. These data support a low-temperature origin of clinoptilolite and contradict the assumption that elevated temperatures are the main controlling factor for authigenic clinoptilolite formation. Increasing clinoptilolite delta18Of values with depth indicate that clinoptilolites which are now in the deeper parts of the zeolite-bearing intervals had either formed at lower temperatures (17-20ºC) or under closed system conditions.
