Non-double-couple microearthquakes at Long Valley caldera, California, provide evidence for hydraulic fracturing (2004)
Journal Article
Foulger, G., Julian, B., Hill, D., Pitt, A., Malin, P., & Shalev, E. (2004). Non-double-couple microearthquakes at Long Valley caldera, California, provide evidence for hydraulic fracturing. Journal of Volcanology and Geothermal Research, 132(1), 45-71. https://doi.org/10.1016/s0377-0273%2803%2900420-7

Most of 26 small (0.4M3.1) microearthquakes at Long Valley caldera in mid-1997, analyzed using data from a dense temporary network of 69 digital three-component seismometers, have significantly non-double-couple focal mechanisms, inconsistent with si...

Time series analysis of long-term river dissolved organic carbon records (2004)
Journal Article
Worrall, F., & Burt, T. (2004). Time series analysis of long-term river dissolved organic carbon records. Hydrological Processes, 18(5), 893-911. https://doi.org/10.1002/hyp.1321

Two long records of dissolved organic carbon (DOC) concentrations in river water were examined by a detailed time series analysis in order to shed light on the mechanisms generating observed increases in DOC concentrations across the UK. The records... Read More about Time series analysis of long-term river dissolved organic carbon records.

The evolution of marine evaporitic brines in inland basins: The Jordan-Dead Sea Rift valley (2004)
Journal Article
Klein-BenDavid, O., Sass, E., & Katz, A. (2004). The evolution of marine evaporitic brines in inland basins: The Jordan-Dead Sea Rift valley. Geochimica et Cosmochimica Acta, 68(8), 1763-1775. https://doi.org/10.1016/j.gca.2003.08.002

Marine-evaporitic brines frequently display Na, Cl and Br concentrations that significantly deviate from seawater evaporation paths, yielding markedly conflicting degrees of evaporation calculated for a specific brine. Here we present 493 new and 33... Read More about The evolution of marine evaporitic brines in inland basins: The Jordan-Dead Sea Rift valley.

Integrated Stratigraphy of the Lower and Middle Fernie Formation in Alberta and British Columbia, western Canada (2004)

Surface wave waveform inversion for variation in upper mantle structure beneath Iceland (2004)
Journal Article
Du, Z., & Foulger, G. (2004). Surface wave waveform inversion for variation in upper mantle structure beneath Iceland. Geophysical Journal International, 157(1), 305-314. https://doi.org/10.1111/j.1365-246x.2004.02202.x

We study the structure of the upper mantle beneath Iceland using surface wave waveforms recorded at pairs of stations lying approximately on the same great circles as the sources used. We invert for local, path-average Vs variations between the stati... Read More about Surface wave waveform inversion for variation in upper mantle structure beneath Iceland.

Late Cenozoic reorganization of the Arabia-Eurasia collision and the comparison of short-term and long-term deformation rates (2004)
Journal Article
Allen, M., Jackson, J., & Walker, R. (2004). Late Cenozoic reorganization of the Arabia-Eurasia collision and the comparison of short-term and long-term deformation rates. Tectonics, 23(2), https://doi.org/10.1029/2003tc001530

The Arabia-Eurasia collision deforms an area of ∼3,000,000 km2 of continental crust, making it one of the largest regions of convergent deformation on Earth. There are now estimates for the active slip rates, total convergence and timing of collision...

Re-Os and Lu-Hf isotope constraints on the origin and age of pyroxenites from the Beni Bousera peridotite massif: implications for mixed peridotite-pyroxenite melting models (2004)
Journal Article
Pearson, D., & Nowell, G. (2004). Re-Os and Lu-Hf isotope constraints on the origin and age of pyroxenites from the Beni Bousera peridotite massif: implications for mixed peridotite-pyroxenite melting models. Journal of Petrology, 45(2), 439-455. https://doi.org/10.1093/petrology/egg102

A suite of pyroxenites from the Beni Bousera peridotite massif, northern Morocco, have been analysed for Re–Os and Lu–Hf isotopic compositions. Measured sections of the massif indicate that pyroxenite layers make up between 1 and 9% by volume of the...

Harzburgite melting with and without H₂O: Experimental data and predictive modeling (2004)
Journal Article
Parman, S., & Grove, T. (2004). Harzburgite melting with and without H₂O: Experimental data and predictive modeling. Journal of Geophysical Research, 109, https://doi.org/10.1029/2003jb002566

The effect of H2O on harzburgite-saturated melts has been quantified with a series of hydrous and anhydrous melting experiments using a piston-cylinder device. Experimental conditions were 1.2–2.2 GPa and 1175–1500°C. Melt H2O contents range from 0 t... Read More about Harzburgite melting with and without H₂O: Experimental data and predictive modeling.
