Vegetation map of the Baikal region, edited by J. Klump, B. Heim and S. Schneider. The map is based on: Isachenko, T. I. (1990): Vegetation of the USSR. Government...

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...

Sediment slices of 0.5 cm thickness were obtained from gravity core segments and of 1 cm thickness from the Vydrino piston core. Volumetric subsamples of 5 cm3 (10 cm3 in case...

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...

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 -...

Geochemical Analysis of Cations of Mud Samples of the KTB Main Hole HB1i

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...

Geochemical Analysis of Anions of Mud Samples of the KTB Main Hole HB1g.

The thermal conductivity on cores is measured in two steps (see Pribnow 1994). First, one face end of the core is sawed and polished. The half space line source is pressed...

Geochemical Analysis of Anions of Mud Samples of the KTB Pilot Hole VB1.

In the KTB field laboratory, porosity, internal surface and permeability were determined on identical mini cores with 25.4 mm in diameter and approximately 50 mm in length....

The qualitative and quantitative phase analyses were performed in the KTB field laboratory by x-ray powder diffraction using SIEMENS D 500 diffractometer. During early stages of...

The vertical distribution of organisms in the sediment indicates that animals can be present as deep as 15 cm although at very low abundance at such depths (Fig. 4, Fig. 5 and...

The porosity was determined using the most common Archimedian method (Schopper, 1982). It is based on the following three weight determinations of the sample: (1) The samples...

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

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...
