(2006)Fluid flow patterns have been determined using oxygen isotope isopleths in the Val-d'Or orogenic gold district. 3D numerical modelling of fluid flow and oxygen isotope exchange in the vein field shows that the fluid flow ...
-
(2003)Sepiolite is a clay mineral with a wide range of applications derived from its sorptive properties. In this work, aspects of the adsorption of Cu(II) and Zn(II) from aqueous solutions to particles of this material have ...
-
(2006)Systematic research of piezoelectric and seismoelectrokinetic phenomena in the context of exploration geophysics began in the former Soviet Union in the mid-1950s. These phenomena are manifested by electrical and electromagnetic ...
-
(2006)The chemistry and crystal structure of a unique Zn-rich kupletskite: (K1.55Na0.21Rb0.09Sr0.01) ∑1.86 (Na0.82Ca0.18) ∑1.00(Mn4.72Zn1.66Na0.41 Mg0.12Fe0.092+∑7.00 (Ti1.85Nb0.11Hf0.03)∑1.99 (Si7.99Al0.12)∑8.11O26 (OH)4(F0.7 ...
-
(2006)EXAFS spectroscopy has been used to determine the medium-range structural environment (within a radius of ≈7 Å) of trace levels of Zn2+ ions within the octahedral sheets of trioctahedral 2:1 phyllosilicates. EXAFS signatures ...
-
(2002)Ferro-manganese nodules of the western Baltic Sea reveal enhanced heavy metal concentrations since the end of the 19th century and are therefore potentially useful for retrospective monitoring of the heavy metal pollution ...
-
(2006)This work is devoted to characterization of zinc interaction in aqueous solution with two marine planktonic (Thalassiosira weissflogii = TW, Skeletonema costatum = SC) and two freshwater periphytic species (Achnanthidium ...
-
(2006)We determined by ICP-MS the concentrations and isotopic ratios of Fe, Cu, and Zn in the Ti-rich lunar basalt 74275, in the lunar orange glass 74220, and in up to 10 lunar soils, namely, 14163, 15231, 64501, 66041, 68841, ...
-
(2006)In this study, the speciation of Zn2+, Pb2+, and Cu2+ ions sorbed at the calcite surface was monitored during a 2.5-year reaction period, using extended X-ray absorption spectroscopy to characterize metal speciation on the ...
-
(2002)A majority of the world's sediment-hosted exhalative (SEDEX) lead-zinc deposits are vent-distal. They are not underlain by a discordant alteration zone or stockwork vent complex that would indicate the path by which ore ...
