(1999)The model of Cr isotopic evolution presented here, relies on the relative volatility properties of the two elements: Mn-Cr in planetary formation processes. The Mn/Cr ratio of the respective parent bodies correlate in most ...
-
(2003)Mössbauer spectra (MS) of two natural magnesian hedenbergite samples (hereafter HED1 and HED2) were collected at temperatures in the range 35 to 800 K. At selected temperatures a longitudinal external field of 60 kOe was ...
-
(2003)The magnetic properties of two natural magnesian hedenbergite samples with slightly different Fe contents (hereafter denoted HED1 and HED2) were studied by transmission 57 Fe Mö ssbauer spectroscopy within the temperature ...
-
(2003)Three natural Fe-bearing diopside samples, hereafter labeled Dp1, Dp2, and Dp3, have been examined by Mössbauer spectroscopy at temperatures from 4.2-800 K. The Fe contents are 0.01, 0.06, and 0.30 atoms per formula unit ...

(Федеральное государственное автономное образовательное учреждение высшего образования «Крымский федеральный университет имени В. И. Вернадского», 2017)Представлен исторический обзор начатых в 1957 году по программе Международного геофизического года геоэлектромагнитных наблюдений на геофизической обсерватории «Алушта». Подобные наблюдения нигде ранее не проводились. ...

(2004)The 7600 14C-year-old Kurile Lake caldera-forming eruption (KO) in southern Kamchatka, Russia, produced a 7-km-wide caldera now mostly filled by the Kurile Lake. The KO eruption has a conservatively estimated tephra volume ...
-
(1998)Three excentroradial pyroxene chondrules from the Semarkona unequilibrated chondrite were analysed by ion microprobe mass spectrometry for their Li-Be-B concentrations and Li and B isotopic compositions. The concentrations ...

(2014)Осенью 2014 года, 22-26 сентября в г. Саппоро, Япония состоялось 8-е международное совещание по процессам в зонах субдукции Японской, Курило-Камчатской и Алеутской островных дуг. Совещание проходило на базе Университета Хоккайдо.
-
(2003)We demonstrate the use of the disequilibrium between 90Sr (t1/2=29.1 yr) and its particle-reactive daughter 90Y (t1/2=64 h) to estimate particle removal rates and settling velocities in the epilimnion of a freshwater lake ...
-
(2005)Metallogenic provinces in Europe range in age from the Archaean to the Neogene. Deposit types include porphyry copper and epithermal Cu–Au, volcanic-hosted massive sulphide (VMS), orogenic gold, Fe-oxide–Cu–Au, anorthosite ...
