(2003)Black shale samples of Jurassic to Cretaceous age recovered during the 'Norwegian Shelf Drilling Program' between 1987 and 1991 from Sites 7430/10-U-01 (Barents Sea), 6814/04-U-02 (Norwegian Shelf near the Lofoten) and ...
-
(2007)New isotopic studies of 142Nd, the daughter product of the short-lived and now extinct isotope 146Sm, have revealed that the accessible part of the silicate Earth (e.g., upper mantle and crust) is more radiogenic in ...
-
(2001)Most komatiite-associated magmatic Ni-Cu-(PGE) sulfide deposits formed from sulfide-undersaturated magmas and are interpreted to have formed in dynamic lava channels or magma conduits by incorporation of crustal sulfur. ...
-
(2002)Titanite/liquid partition coefficients for most of the trace elements relevant in petrogenetic studies are provided for titanite-saturated liquids equilibrated at 1.5 GPa and 850 °C starting from lamproitic compositions. ...
-
(1987)The authors used multivariate statistical methods to evaluate trace-element associations in tourmaline for the purpose of establishing the vertical zoning of tourmaline-type tin-ore deposits and employing it to estimate ...
-
(2003)This study examines the effects of increasing supersaturation, attained by single-step liquidus undercooling (ΔT), on the partitioning of barium and cesium between potassic alkali feldspar (Afs) and hydrous granitic liquid ...
-
(2003)To establish more fully a basis for quantifying the role of apatite in trace-element fractionation processes, hitherto unknown mineral/melt partition coefficients (Dapatite/melt) for a variety of trace elements (Li, Be, ...
-
(2004)Olivine/liquid partition coefficients for most trace elements relevant in petrogenetic studies are provided for a hydrous basanite melt equilibrated at 1.4 GPa and 1055 °C. The partitioning results determined by a combination ...
-
(2002)Although often studied as key constituent in minerals, the low mass element (Z = 4; M = 9.0012182 amu) beryllium is most commonly encountered as a very low abundance trace metal in rocks and fluids. In terms of atomic ...
-
(2002)We employed the thin source technique to investigate tracer diffusion of Mg, Ca, Sr, and Ba in glasses and supercooled melts of albite (NaAlSi3O8) and jadeite (NaAlSi2O6) compositions. The experiments were conducted at 1 ...
-
(1997)Tracer diffusion coefficients of K, Rb, and Cs were determined in a supercooled jadeite melt using the thin source technique. Experiments were performed at temperatures between 800 and 1020°C at 1 bar pressure. Run times ...

TRACERS OF THE EXTRATERRESTRIAL COMPONENT IN SEDIMENTS AND INFERENCES FOR EARTH'S ACCRETION HISTORY (2002)The study of extraterrestrial matter in sediments began with the discovery of cosmic spherules during the HMS Challenger Expedition (1873-1876), but has evolved into a multidisciplinary study of the chemical, physical, and ...
-
(2003)Stable N isotopes are used to examine the source, flow and fate of N at scales ranging from greenhouse pots to landscapes. There are two main approaches: the 15N-enriched method applies an artificially enriched source of ...
-
(2002)We detail here the general concepts behind using noble gases as a tracer of crustal fluid processes and illustrate these concepts with examples applied to oil-gas-ground-water systems, mineralizing fluids, hydrothermal ...
-
(2004)Following previous publication of major---minor element data, this paper presents rare earth element (REE) data for heterogeneous (chemically zoned) garnets belonging to the peridotite suite of mantle xenoliths from the ...
-
(2003)Tectonic activity, on a range of scales, is a fundamental control on sedimentary activity. The range of structural deformation within a region extends from the plate tectonic scale, governing, for example, rift initiation, ...
-
(1998)A unique record of the chemical evolution of seawater during hydrothermal recharge into oceanic crust is preserved by anhydrite from the volcanic sequences and sheeted dike complex in ODP Hole 504B. Chemical and isotopic ...
