119SN MOSSBAUER STUDY OF CASSITERITE-RUTILE SOLID SOLUTIONS, (SN(1-X)TI(X))O2

Urusov V.S.; Khramov D.A.; Langer K. (1999)

Single phase rutile-cassiterite solid solutions (Sn(1-x)Ti(x))O2 with x = 0.00, 0.15, 0.30, 0.47, 0.70, 0.90, 0.99, 1.00 were synthesized above the solvus temperatures in the system SnO2-TiO2, cassiterrite-rutile, from ...
EPR STUDY OF CR3+ DOPING CENTERS IN MG2SIO 4: CR,LI CRYSTALS AND A COMPUTER STRUCTURE SIMULATION

Mineeva R.M.; Kamozin P.N.; Dudnikova V.B.; Urusov V.S.; Gaister A.V.; Zharikov E.V. (2003)

Powdered samples of Mg2SiO4: Cr and Mg 2SiO4: Cr,Li crystals have been studied using EPR spectroscopy. In chromium-doped forsterite crystals, Cr M31+ and Cr M32+ octahedral centers and tetrahedral Cr4+ centers have been ...
FIRST-PRINCIPLES STUDY OF (MGH2SIO4) • N(MG2SIO4) HYDROUS OLIVINE STRUCTURES. I. CRYSTAL STRUCTURE MODELLING OF HYDROUS OLIVINE HY-2A (MGH2SIO4) • 3(MG2SIO4)

Churakov S.V.; Wirth R.; Khisina N.R.; Urusov V.S. (2003)

Recently, the Hy-2a hydrous olivine (MgH2 SiO4)·3(Mg2SiO4) occurring as nanometre-sized inclusions in mantle olivines has been found by TEM, and has been suggested to be a new DHMS phase (Khisina et al. 2001). A model of ...
MGAL2O4 SPINEL - PECULIARITIES OF ITS ATOMIC AND ELECTRONIC-STRUCTURE DEDUCED FROM PRECISION X-RAY-DIFFRACTION DATA

Tsirel'son V.G.; Belokoneva E.L.; Urusov V.S.; Nozik Y.Z. (1986)
NATURE OF AL-SI ANTIORDERING IN A TWO-PHASE FELDSPAR FROM PEKTUSAN VOLCANO, PRIMORIE

Oganov A.R.; Oganova N.I.; Urusov V.S. (2001)

The phenomenon of antiordering, i.e., preferred Al occupation of the T-2o position of the albite structure, was observed in a two-phase feldspar from Pektusan Volcano, Primorie. This paper reports the results of the computer ...
RECALIBRATION OF THE SPHALERITE COSMOBAROMETER: EXPERIMENTAL AND THEORETICAL TREATMENT

Balabin A.I.; Urusov V.S. (1995)

Temperature dependence of the composition of sphalerite in equilibrium with troilite + metallic iron has been determined experimentally from 400 to 840°C at 1 bar. The high-temperature runs (660–840°C) were conducted in ...
THE TRACE-COMPONENT TRAPPING EFFECT: EXPERIMENTAL EVIDENCE, THEORETICAL INTERPRETATION, AND GEOCHEMICAL APPLICATIONS

Urusov V.S.; Dudnikova V.B. (1998)

Experimental data indicating increase of crystal-melt (fluid) partition coefficients in the range of microconcentrations of trace elements are reviewed and analyzed in detail. This concentration dependence of partition ...
