(1988)We have developed a migration method for scalar components of the electromagnetic field that can be used to reconstruct the locations of geoelectric nonuniformities from the measured components of the magnetic or electric ...
-
(1988)We attempted a new approach to evaluating the migrational ability of minerals, based on their settling rates, one of the fundamental values governing the placer-forming properties of minerals. Since we were interested in ...

-
(2004)The abundances of the mildly incompatible elements Al, Cr, V, Sc and Yb in more than 1700 mantle peridotite bulk rock analyses are interpreted in the light of a fractional melting model based on experimentally measured ...
-
(2004)Diatom analysis of two submarine cores off eastern Hokkaido Island, northern Japan, provides insights into the Holocene palaeoenvironmental history of the southwestern Okhotsk Sea. Diatom flora was mainly composed of ...
-
(2001)Central-type endogenic structures (CTS) are a class of injective deformations of crustal and mantle origin, which control distribution of deposits and areas of accumulation of different-type mineral resources (metal ores, ...
-
(1996)The Inagli complex, one ot several Mesozoic intrusive complexes of the Aldan Shield (Siberian Platform), exhibits a concentric structure comprising several alkaline ultramafic rock-types. A central dunite body is surrounded ...
-
(1998)A comprehensive study of the petrography, cathodoluminescence (CL), rare earth element (REE) abundances, and magnesium and silicon isotopic compositions of enstatite, the major mineral in unequilibrated enstatite chondrites ...

-
(1996)Ion microprobe analyses of REE and other selected trace and minor elements, coupled with electron microprobe measurements of major elements, were made in pigeonite, plagioclase, and phosphates of eight noncumulate eucrites ...
-
(1997)We carried out an ion microprobe study of REEs and other selected trace and minor element concentrations in orthopyroxene, augite lamellae, and plagioclase of two cumulate eucrites Moama and Moore County in order to ...
-
(2002)Presents an abstract of the article 'Mineral Chemistry and the Provenance of Zircon Samples,' by K. Vernier, T.S. Ercit and R.P. Taylor presented at the 28th Rochester Mineralogical Symposium.
-
(2001)Zircon-bearing veins in a harzburgite xenolith from kimberlite have imposed Ca-metasomatism on the harzburgite wall rock, in addition to adding K, Fe, Ti and OH. The zircon, previously dated to have an age similar to that ...
-
(2006)Major- and trace-element data on the constituent minerals of garnet peridotite xenoliths hosted in early Paleozoic (457–500?Ma) kimberlites and Neogene (16–18?Ma) volcanic rocks within the North China Craton are compared ...
-
(2004)Ophiolites of the southern Uralides arc-continent collisional orogen include fertile mantle lherzolites and minor harzburgites in the Nurali and Mindyak massifs located along the Main Uralian Fault suture of the East ...
-
(2002)Reviews the book 'Mineral Collections of Russia, Part II—Twelve Museum Collections,' edited by Dmitrii V. Rundqvist.
