Composition of Cosmic Spherules from Ferromanganese Crusts of the Magellan Seamounts

Autor: D. P. Savelyev, O. L. Savelyeva, S. V. Moskaleva, V. A. Rashidov

Publikováno v: Geochemistry International. 60:411-420

Abstract— 2720 cosmic spherules extracted from ferromanganese crusts sampled at two guyots of the Magellan Seamounts were studied using a scanning electron microscope. In comparison with collections of modern cosmic spherules, our samples are signi

Carbonaceous Rocks in Cretaceous Deposits of the Kamchatsky Mys Peninsula: Geochemistry, Metal Accumulation, and Sedimentation Conditions

Autor: D. P. Savelyev, O. L. Savelyeva, S. V. Palesskii

Publikováno v: Russian Journal of Pacific Geology. 15:211-223

Carbonaceous beds have been studied in the Cretaceous paleo-oceanic deposits of Eastern Kamchatka; their origin relates to the anoxic oceanic events. In the carbonaceous rocks, the contents of trace elements and noble metals: Ba, Cu, Ni, Zn, Mo, V, U

Publikováno v: Petrology. 29:14-23

Abstract We conducted the geochemical modeling of trace element contents for primary melts of olivine-phyric rocks from Kamchatsky Mys. This modeling reveals substantial chemical heterogeneity of their source while the average source composition is c

First Find of Platinum in Cosmogenic Spherules of Ferromanganese Crusts (Fedorov Guyot, Magellan Seamounts, Pacific Ocean)

Autor: P. E. Mikhailik, O. L. Savelyeva, A. I. Khanchuk, D. P. Savelyev, S. V. Moskaleva

Publikováno v: Doklady Earth Sciences. 491:199-203

More than 250 magnetic spherules 40–200 µm in size were mechanically separated from a ferromanganese crust sample of Fedorov Guyot in the Magellan Seamounts. The composition of the spherules corresponds to stony-iron and iron (with a nickel admixt

The source of platinum group elements in basalts of the ophiolite complex of the Kamchatsky Mys Peninsula (Eastern Kamchatka)

Autor: S. V. Palesskii, Maxim Portnyagin, D. P. Savelyev

Publikováno v: Russian Geology and Geophysics. 59:1592-1602

Contents of platinum group elements (PGE—Os, Ir, Ru, Rh, Pt, and Pd) and rhenium in basalts of different geochemical types from the ophiolite complex of the Kamchatsky Mys Peninsula have been determined by the isotope dilution–mass spectrometry m

Publikováno v: American Mineralogist, 103 (6). pp. 886-898.

Silicate-sulfide liquid immiscibility in mantle-derived magmas has important control on the budget of siderophile and chalcophile metals, and is considered to be instrumental in the origin orthomagmatic sulfide deposits. Data on primitive sulfide mel

Publikováno v: Lithos. :105657

Highlights • Parental melts of sulfide-bearing KM rocks have near primary MORB-like composition. • Crystallization of these S-saturated melts occurred in near-surface conditions. • Extensive fractionation and crustal assimilation are not the ca
