Corrosion products have been taken from 130 copper or bronze outdoor objects all over Europe. Their chemical composition and crystal symmetry have been determined by means of scanning electron...
Mark, G., Williams, P.J., Boyce, A.J.
Hydrothermal alteration within the Mount Isa Block (MIB) is typically largely to have ceased at the end of the Isan Orogeny (ca. 1.50 Ga). However, late, large brittle quartz-rich vein systems,...
Origin of the copper-cobalt deposits of the Zambian copperbelt: an epigenetic view from Nchanga
McGowan, R.R., Roberts, S., Foster, R.P., Boyce, A.J., Coller, D.
The Zambian Copperbelt is arguably the most significantly mineralized Neoproterozoic basin on Earth, preserving a truly spectacular scale of mineralization: in excess of 1 X 10(9) t of ore at similar...
Palero, F.J., Both, R.A., Arribas, A., Boyce, A.J., Mangas, J., Martin-Izard, A.
The Alcudia Valley is intensely mineralized, with a large number of Pb-Zn-Ag-Cu deposits hosted by Neo-proterozoic and Paleozoic sedimentary rocks. Five distinct types of deposits have been...
Rice, C.M., Harmon, R.S., Boyce, A.J., Fallick, A.E.
Important epithermal tungsten mineralization in the Boulder County district is mainly hosted by quartz-ferberite (FeWO4) veins. Isotopic studies based on an extensive grid (deltaD) and individual...
Richards, J.P., Boyce, A.J., Pringle, M.S.
A program of geologic mapping and lithogeochemical and geochronological sampling has been carried out over a 745-km(2) area of the Atacama Desert surrounding the porphyry Cu deposits at Escondida,...
Vroon, P.Z., Lowry, D., Van Bergen, M.J., Boyce, A.J., Mattey, D.P.
This study reports new laser fluorination oxygen isotope data for 60 volcanic rocks and 15 sediments distributed over the whole length of the Banda Are, eastern Indonesia. The melt oxygen isotope...
Syntectonic hydrothermal Pb-Zn vein systems of the Ramsbeck deposit. Germany, have been extensively overprinted by late- stage fluids responsible for fissure vein mineralisation. This has caused...
Barker, A.J., Bennett, D.G., Boyce, A.J., Fallick, A.E.
Hypersaline (Na-Ca-Cl) fluids are associated with late-stage quartz veining and retrogression of garnet, kyanite and other high P-T phases in the vicinity of thrusts and major lithological boundaries...
From basin to basement: the movement of surface fluids into the crust
Gleeson, S.A., Yardley, B.W.D., Boyce, A.J., Fallick, A.E., Munz, L.A.
Quartz veins from Precambrian, high grade, basement rocks in Southern Norway contain both aqueous and biogenically sourced hydrocarbon fluid inclusions. Aqueous fluids show a wide range in salinities...
Sulphur isotope variations in diagenetic pyrite from core plug to sub-millimetre scales
McConville, P., Boyce, A.J., Fallick, A.E., Harte, B., Scott, E.M.
Sulphur isotope ratio measurements (delta(34)S) of diagenetic pyrite an commonly used to identify S sources and mechanisms of sulphide formation in basinal sediments. This study reports: such data...
