Chemical composition of <0.001 mm grain size fraction from sedimentary rocks and bottom sediments of the Philippine Sea

Distriburtion and formation of clay minerals in different types of bottom sediments from the West Pacific are under consideration.

Paleomagnetism of serpentinized peridotites from ODP Hole 109-970A

Paleomagnetic studies on the serpentinized peridotites recovered from ODP Hole 670A were conducted in three laboratories. High NRM intensities and magnetic susceptibilities were observed in the serpentinized peridotites, which suggest that the remanent and the induced magnetizations of the peridotites cannot be neglected as a source of the magnetic anomalies observed at sea surface. The in situ low inclination of the magnetization indicated from the laboratory studies suggests that the peridotite body has been subjected to a large-scale deformation after the acquisition of the magnetization.

Chemical composition of rocks and minerals from the Central Atlantic fracture zones

The monograph summarizes materials on geology and deep structure of the Central Atlantic fracture zones. These materials have been obtained during eight expeditions of R/V ''Akademik Nikolaj Strakhov''. The studies have been based on the integrated geological approach. As a result, many new tectonic, magmatic, metallogenic and historical-geological features of these phenomenal structures of the deep ocean have been revealed.
