Contents of Ag, Bi, In, and Tl in suspended and aerosol matter at Station DM8-579 in the Peru Basin, Southeast Pacific

A new electrothermal atomizer for use in direct determination of Ag, Bi, In, and Tl in marine, riverine, and aeolian particulate matter on membrane filters is described. A sample capsule and atomization cell are heated separately. That is why it is possible to separate and optimize decomposition of a sample, vaporization of elements and atomization of their vapors. Noise reduction and design, which localizes the vapors in a light absorption zone, decrease detection limits of these four elements by factor of at least 3 to 10. Some analytical results are given.

K-Ag age of volcanites from underwater rises of the Sea of Okhotsk and the Sea of Japan

New K-Ar datings of Meso-Cenozoic volcanites from the Sea of Japan and the Sea of Okhotsk were obtained. They enabled to reason age of different volcanic complexes. Basalts from volcanic edifices of the Sea of Japan Basin were determined as Middle Miocene - Pliocene (13.1-4.5 Ma) in age, which correlates well with geological evolution of the Sea of Japan. New datings for basalts from the continental slope of the South Primorye (11.1 Ma) confirm their age being similar to volcanites from Neogene basalt plateaus of the South Primorye; they are very similar not only in age but also in mineral and chemical compositions. Datings for rocks from the andesite series of the Northern Yamato Rise (24.7, 21.5 Ma) show that they are coeval with volcanites of the trachyandesite complex; this allows to combine them into one Oligocene - Early Miocene complex. In the Sea of Okhotsk datings of volcanite samples from three complexes were obtained: Cretaceous, Paleogene, and Pliocene-Pleistocene. Cretaceous magmatic rocks make part of basements of large rises in the Sea of Okhotsk, and Paleogene and Pliocene - Pleistocene complexes illustrate stages of Cenozoic tectono-magmatic activation of the region.
