The main objective of this drilling fluid analysis was the detection of inflows of formation fluids. Therefore different gases dissolved in the drilling mud were measured...

Ultrasonic wave propagation through core samples is studied in a water tank to insure good signal transmission between transducer, rock specimen and receiver and to avoid time -...

We made magnetic measurement of 32 cubic specimens of sub-bottom sediments of Lake Baikal. These are part of the sub-samples for palaeomagnetic investigations obtained from the...

SAFOD is motivated by the need to answer fundamental questions about the physical and chemical processes controlling faulting and earthquake generation within a major...

The concentration in ferromagnetic particles is much lower in the interglacial sediments than in glacial sediments. Therefore, the NRM needs to be normalised by a...

The magnetic susceptibility is measured by an inductive AC device (BARTINGTON). The sample is placed inside a coil which generates an alternating magnetic field. The applied...

Water content and dry bulk density of pilot core CON01-604-2a to piston core CON01-604-2 from Posolskoe

During 16 months of deployment, 239 g m−2 dry matter settled in the 40-m trap, with an average flux of 14.9 g m−2 month−1 (Table 2 and Fig. 2). The content of organic carbon was...

The Alpine Fault, New Zealand, is a major plate-bounding fault that accommodates 65–75% of the total relative motion between the Australian and Pacific plates. Here we present...

Dissolution was high throughout the profile—in most cases, only 10–20% of the valves considered as pristine (Fig. 4). High relative percentages of A. baicalensis and of benthic...

The temperature pattern is attributed to a superposition of thermal and hydraulic processes. In the deeper borehole (HSDP-2, depth 3.1 km) detailed temperature monitoring was...

Three representative vector endpoint diagrams: (A) sample from a clay-rich layer, exhibiting normal polarity; (B) sample from a clay-rich layer, exhibiting reverse polarity,...

Ultrasonic wave propagation through core samples is studied in a water tank to insure good signal transmission between transducer, rock specimen and receiver and to avoid time -...

In the laboratory, the gamma radiation is measured by a sodium iodtite (NaI) scintillation detector (cores and cuttings) and by a germanium (Ge) semiconductor detector...

Geochemical Analysis of Anions of Mud Samples of the KTB Pilot Hole VB1b.

The density of rocks depends on the mineral contents and is therefore a helpful property for the discrimination of lithological units. It is also used for the calculation of...

Wet bulk density (GRAPE) of piston core CON01-603-2 from CONTINENT Ridge

Diatom-inferred snow depth reconstructions for BAIK38 using uncorrected taxa (Fig. 5a–c) show similar trends throughout the study period, with all or only five taxa in the...

Fig. 4 visualises differences in the degradation between the organic compounds, chlorophylls, and carbon. The chlorophyll a/carbon ratio decreased with depth, indicating that...

In the KTB field laboratory, thermal conductivity was measured on cuttings material in depth intervals of 10 m and on available drill core material. The results on drill cores...
