Zn, Fe and S isotope fractionation in a large hydrothermal system

Gagnevin, Damien ; Boyce, Adrian ; Barrie, Craig ; Menuge, Julian ; Blakeman, Robert (Elsevier, 2012-07-01)

The genesis of hydrothermal ore deposits is of crucial economic importance. This study investigates the extent, causes and consequences of zinc and iron isotope fractionation in a large hydrothermal system at the world-class ...
Large-scale, linked drainage systems in the NW European Triassic: insights from the Pb isotopic composition of detrital K-feldspar

Tyrrell, Shane ; Souders, A. Kate ; Daly, J. Stephen ; Shannon, Patrick M. ; Haughton, P. D. W. (The Geological Society, 2012-05)

Pb isotopic data from K-feldspars in Middle Triassic (Anisian) sandstones in the Wessex Basin, onshore southwest UK, and the East Irish Sea Basin, some to the north, show that the same grain populations are present. This ...
A late-Holocene climate record in stalagmites from Modrič Cave (Croatia)

Rudzka, Dominika ; McDermott, Frank ; Suric, Masa (Wiley, 2012)

Few terrestrial Holocene climate records exist from Southeastern Europe despite its important geographic position as a transitional climatic zone between the Mediterranean and mainland continental Europe. In this study we ...
The coupled δ13C-radiocarbon systematics of three late Glacial/early Holocene speleothems; insights into soil and cave processes at climatic transitions

Rudzka, Dominika ; McDermott, Frank ; Baldini, Lisa M. ; Fleitmann, Dominik ; Moreno, Ana ; Stoll, Heather (Elsevier, 2011-08-01)

The coupled δ13C-radiocarbon systematics of three European stalagmites deposited during the Late Glacial and early Holocene were investigated to understand better how the carbon isotope systematics of speleothems respond ...
Source separation on seismic data : application in a geophysical setting

Moni, Aishwarya ; Bean, Christopher J. ; Lokmer, Ivan ; Rickard, Scott (Institute of Electrical and Electronic Engineers, 2012-05)

This article gives a brief description of the Degenerate Unmixing Estimation Technique (DUET) and applies it in a geophysical setting. Source separation has not been fully addressed by geophysicists and is a crucial first ...
