-
(2003)The morphology and chemistry of small grains (microlites and daughter phases in melt inclusions) of 20 minerals were examined in rocks from the Malomurunskii Massif. Along with minerals previously known in the massif, the ...
-
(2004)Cold springs upwelling through large serpentinite mud volcanoes in the outer half of the Mariana forearc provide a unique window into processes of devolatilization of the subducting Pacific Plate. We have sampled upwelling ...
-
(2003)The Calcalong Creek lunar meteorite is a polymict breccia that contains clasts of both highlands and mare affinity. Reported here is a compilation of major, minor, and trace element data for bulk, clast, and matrix samples ...
-
(1990)One of the important unsolved problems regarding the serpentinization of Kimberlite is the mineragenetic and chemical direction of this process in its various stages. We analyzed this development on a series of specimens ...
-
(2005)The formation of the Ries impact and the moldavites have identical radiogenic ages of 14.3 Ma. According to this conformity in age moldavites are generally regarded as products of the Ries impact. This paper, which is ...
-
(2002)Current chemostratigraphical studies of the Jurassic System primarily involve the use of one sedimentary component (marine organic carbon), one divalent transition metal substituted in carbonate (manganese), and two isotopic ...
-
(1998)A tephrochronological study and radiocarbon dating of soil-pyroclastic sequences were carried out along a profile of Shiveluch Volcano-Chernyi Yar-Bering Islands. Ashes deposited by the largest Shiveluch eruptions (for the ...
-
(2004)The crystal structure of annealed chevkinite-(Ce), ideally (REE,Ca)4 Fe 2+ (Ti,Fe 3+ ,Nb)4 Si4 O22, monoclinic, C2/m, crystal (2 an ) a 13.400(1), b 5.7232(4), c 11.0573(9) A, � 100.537(2), V 833.7(2) A 3 and crystal (3 ...
-
(2002)The South Korea Plateau is a complex of ridges, seamount chains, troughs and a basin. Detailed analysis of 12#019 line-km Chirp (2-7-kHz) subbottom profiles from the South Korea Plateau and the eastern continental slope ...
-
(2002)Chirp sub-bottom profilers are marine sonar systems which use a highly repeatable source signature to facilitate the acquisition of correlated data with decimetre vertical resolution in the top 20-30 m of sediments. Source ...
-
(2004)Diverse and abundant assemblages of chitinozoans allow the recognition of the upper part of the Margachitina margaritana Biozone in the uppermost Llandovery and lowermost Wenlock series of the Hughley Brook section. The ...
-
(2003)Chlorbartonite, ideally K6Fe24S26(Cl,S , is a new potassium iron sulfide chloride found as an accessory mineral in a microcline - pectolite - sodalite - aegirine vein within feldspathic urtite at Mount Koashva, Khibina ...
-
CHLORIDE AND WATER SOLUBILITY IN BASALT AND ANDESITE MELTS AND IMPLICATIONS FOR MAGMATIC DEGASSING (1999)The solubilities of chloride (Cl−) and H2O in aluminosilicate melts of basalt, andesite, and latite compositions saturated in aqueous vapor and/or hydrosaline liquid were determined at 2000 bars and ≈1 bar by melting ...
-
(1986)Consideration of the geochemistry of Cl and I suggests that both elements would be useful pathfinders for hydrothermal mineralization. The results of published case studies indicate that these halogens form broad dispersion ...
-
(1995)This first investigation of the Cl stable isotope composition of seafloor rocks reveals systematic variations in37Cl35Cl of the oceanic crust and its mantle source(s) relative to seawater. Chlorine isotopic measurements ...
-
(1995)Chlorine isotope fractionation (37Cl/35Cl) between NaCl, KCl, and MgCl2.6H2O and their saturated solutions was determined in laboratory experiments at 22 +/- 2°C. The results are as follows:103 1n α(NaCl--solution) = +0.26 ...
-
(1997)Eight carbonatite samples were analysed for δ37Cl and for δ18O and δ13C. The results show that unaltered carbonatites have δ37Cl ratios between −0.8 and +0.1‰. Because the whole mantle δ37Cl value is approximately +4.7‰, ...
-
(2000)A distinct peak has been discovered in the 36Cl data from the GRIP ice core between the Dansgaard Oeschger (D-O) events 6 and 7 at approximately 32 kyr BP. This peak can be attributed to a minimum of the geomagnetic dipole ...
-
(2003)The dissolution of chlorite with intermediate Fe-content was studied macroscopically via mixed flow experiments as well as microscopically via atomic force microscopy (AFM). BET surface area normalized steady state dissolution ...
