-
(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 ...
-
(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.
-
(2003)Upper Jurassic petrified bone remains of dinosaurs from the Kalbak-Kyry locality are described. Three types of mineralization arc recognized. The mineral composition and mineralization of collagen are described.
-
(2002)This special issue includes articles resulting from the presentations at the symposium: "Mineral Equilibria in Mantle-Derived Rocks", which took place on August 8–9, 2000 at the 31st International Geological Congress in ...
-
(1993)We investigated the equilibrium mineral assemblages in chemically fractionated nebular systems, using a computer routine that finds the set of minerals and gases which minimizes the Gibbs free energy of a system with ...
-
(2001)We model three cases of coupling between mineral growth kinetics and mechanical response of the rock: (i) dispersed spherical crystals growing by replacement in a hydrostatically stressed elastic rock; (ii) growth of veins ...
-
(2004)Chemical compositions were determined onmineral inclusions recovered from 290microdiamonds ( < 1mm) from 8 operating diamond mines in Yakutia. The sampled diamond mines include Mir, Udachnaya, Internatsionalnaya, Aykhal, ...
-
(2002)In order to constrain the metamorphic evolution of deeply subducted impure marble from the Kokchetav massif, we investigated mineral inclusions in zircon, which is known to protect ultrahigh-pressure (UHP) phases from ...
-
(1996)A study was made of Carboniferous deltaic deposits from Verkhoyan. The study was based on an analysis of the composition and typomorphic characteristics of the mineral parageneses in the deposits. This was accompanied by ...
-
(2004)Mineral-magnetic measurements and analysis of total organic carbon (TOC) and carbon/nitrogen (C/N) were performed on two AMS 14C-dated lacustrine sequences recovered from Xiaoniuchang and Jiangjunpaozi (∼42°N, 117°E). The ...
-
(2001)Pitfalls encountered when dealing the mica crystal chemistry on the basis of routine chemical analyses are reviewed.
