SAFOD Main Hole downhole logging data phase 1.2 1744-1932m

SAFOD

2008

SAFOD is motivated by the need to answer fundamental questions about the physical and chemical processes controlling faulting and earthquake generation within a major plate-bounding fault. SAFOD will drill and instrument an inclined borehole across the San Andreas Fault Zone to a depth of 3.2...

Selected electron-microprobe analyses of vivianite and santabarbaraite from Lake Baikal

Fagel, Natalie | Alleman, Laurent | Granina, L | Hatert, F | Thamo-Boszo, Edit | Cloots, R | André, Luc

2006

Electron-microprobe analyses (Table 5) were completed on a selection of grains from 11 samples, with a CAMECA SX-50 instrument (University of Louvain-la-Neuve, Belgium), under an accelerating voltage of 15 kV and a probe current of 20 nA. The standards used were the Kabira graftonite (Fe, Mn,...

Composition of major oxide in bulk sediments from lake Baikal: ICP-AES data from P-rich samples

Fagel, Natalie | Alleman, Laurent | Granina, L | Hatert, F | Thamo-Boszo, Edit | Cloots, R | André, Luc

2006

The sediment cores were sampled with a resolution of 10 cm, resulting in a total of 290 samples (Table 2). Around 250 mg of dried sediments was mechanically crushed through 100–200-μm mesh then processed by an alkaline digestion (Lithium meta-borate) in a Pt crucible at 1000 °C for 1 h. The...

Age models based on palaeomagnetic measurements for the two cores analysed, CON01-603-2 (Continent Ridge) and VER98-1-14 (Academician Ridge) showing the correlation points to the reference record

Rioual, Patrick | Mackay, Anson

2006

Palaeomagnetism was the method used for dating sediments older than the time span covered by AMS 14C dating. Geomagnetic palaeointensities recorded in Lake Baikal sediments were tuned to a reference curve (the record from ODP Site 984, Channell, 1999) whose chronology is well constrained...

Data concerning preparation of pollen concentrates and graphite targets and results of dating.

Piotrowska, Natalia | Bluszcz, Andrzej | Demske, Dieter | Granoszewski, Wojciech | Heumann, Georg

2006

Laboratory processing of concentrates was aimed at the removal of non-sporomorph organic matter by means of chemical treatment, micro-sieving and heavy liquid seperation. The optained concentrates were checked under the microscope and sample purity was estimated on the basis of particle...

High temperature measurements of magnetic susceptibility in diatomaceous layers for VER98-1-1

Demory, Francois | Oberhänsli, Hedi | Nowaczyk, Norbert | Gottschalk, Matthias | Wirth, Richard | Naumann, Rudolf

2006

High temperature measurements of magnetic susceptibility in diatomaceous layers. Most of the weak susceptibility is still present up to the temperature of 670 °C and carried by hematite.

High temperature measurements of magnetic susceptibility in clay-rich layers for VER98-1-14

Demory, Francois | Oberhänsli, Hedi | Nowaczyk, Norbert | Gottschalk, Matthias | Wirth, Richard | Naumann, Rudolf

2006

High temperature measurements of magnetic susceptibility in clay-rich layers. Magnetite, characterised by a Curie temperature of 590 °C, dominates the signal.

Downcore variations of rock magnetic parameters for the sedimentary sequence of VER98-1-14

Demory, Francois | Oberhänsli, Hedi | Nowaczyk, Norbert | Gottschalk, Matthias | Wirth, Richard | Naumann, Rudolf

2006

Downcore variations of rock magnetic parameters and simplified lithological description for the sedimentary sequence VER 98-1-14. Here, MIS are denoted by numbers in the lithological column. The black squares filled intervals mark occurrences of greigite characterised by a high magnetic...

Down-core variations of the inclination and declination of ChRM of all investigated cores.

Demory, Francois | Nowaczyk, Norbert | Witt, Annette | Oberhänsli, Hedi

2006

Dashed lines mark some correlation levels of the cores from Lake Baikal with the dated δ18O record from ODP 677 (Shackleton et al., 1990), see also Fig. 3. Diagenetic features such as dissolution of magnetite and mineralization of greigite are marked according to Fig. 4. Laschamp and Iceland...
