Basic Researches Magnetostratigraphy of sea and continental deposits of Pliocene-Quaternary, Neogen-Paleogene, Mesozoic and Paleozoic ages throughout the North-East of Asia; development of a magnetochronologic scale of Phanerozoic Geodynamic reconstructions on basis of paleomagnetic data obtained for the North-East of Russia Magnetic properties and magnetic mineralogy of sedimentary and igneous rocks;
Paleomagnetism and magnetostratigraphy of sea bottom rocks world-wide; the rates of sea bottom sedimentation processes Magnetomineralogical and paleomagnetic characteristics of iron-manganese concretions over the sea bottom
Basic Research Results
The correlational schemes of Cenozoic rocks have been developed for the North-East of Russia on basis of magnetostratigraphic data obtained for continental rock sequences in central and eastern Yakutia and the Upper Kolyma River area, also for sea and continental rock sequences in Chukotka, Kamchatka and Koryakia; paleomagnetic characteristics of some Cenozoic events and geological boundaries are established; the permafrost processes are shown to affect the rock magnetization. A composite magnetostratigraphic scale of Paleozoic has been developed for the North-East of Russia, on basis of bio- and magnetostratigraphic data; the paleopole coordinates are established for some boundary levels of Paleozoic for Omulyovka and Kolyma Uplifts and Omolon Massif. Magnetostratigraphic data obtained about bottom sediments of the Pacific are generalized; the schematic maps of rock thickness distribution through time intervals of Pliocene and Pleistocene are made. Iron-manganese concretions from sea bottom of the Pacifc, which inherit the information about ore-forming processes and their rates, have been described from viewpoints of their paleomagnetic and magnetic-mineralogical properties. A tensor model of oriented magnetization has been created for sea and lake bottom sediments, which display a different granulometric characteristics of their magnetic particles.
