Dynamic modelling of a UK North Sea saline formation for CO2 sequestration (2014)
Journal Article
Watson, F., Mathias, S., Daniels, S., Jones, R., Davies, R., Hedley, B., & van Hunen, J. (2014). Dynamic modelling of a UK North Sea saline formation for CO2 sequestration. Petroleum Geoscience, 20(2), 169-185. https://doi.org/10.1144/petgeo2012-072

Preliminary dynamic modelling, using TOUGH2/ECO2N, has been carried out to assess the suitability of a site in the UK North Sea for sequestering CO2. The potential storage site is a previously unused saline formation within the Permian Rotliegend san... Read More about Dynamic modelling of a UK North Sea saline formation for CO2 sequestration.

Potential field and bathymetric investigation of the Monowai volcanic centre, Kermadec arc: implications for caldera formation and volcanic evolution (2014)
Journal Article
Paulatto, M., Watts, A., & Peirce, C. (2014). Potential field and bathymetric investigation of the Monowai volcanic centre, Kermadec arc: implications for caldera formation and volcanic evolution. Geophysical Journal International, 197(3), 1484-1499. https://doi.org/10.1093/gji/ggt512

The dynamics of caldera formation are affected by internal factors, such as magma chamber structure and properties and regional tectonic stresses. Understanding their interrelationship is important for assessing volcanic hazard and reconstructing the...

Sub-lithospheric small-scale convection—a mechanism for collision zone magmatism (2014)
Journal Article
Kaislaniemi, L., van Hunen, J., Allen, M., & Neill, I. (2014). Sub-lithospheric small-scale convection—a mechanism for collision zone magmatism. Geology, 42(4), 291-294. https://doi.org/10.1130/g35193.1

We studied the effect of increased water content on the dynamics of the lithosphere-asthenosphere boundary in a postsubduction setting. Results from numerical mantle convection models show that the resultant decrease in mantle viscosity and the perid...

Shifts in discharge-concentration relationships as a small catchment recover from severe drought (2014)
Journal Article
Burt, T., Worrall, F., Howden, N., & Anderson, M. (2015). Shifts in discharge-concentration relationships as a small catchment recover from severe drought. Hydrological Processes, 29(4), 498-507. https://doi.org/10.1002/hyp.10169

This paper provides evidence of the recovery of a small, moorland catchment to a severe drought, the most extreme on record in the UK. We present a detailed water quality time series for the post-drought recovery period, from the first significant st...

Trace element budgets and (re)distribution during subduction-zone ultrahigh pressure metamorphism: Evidence from Western Tianshan, China (2014)
Journal Article
Xiao, Y., Niu, Y., Li, H., Wang, H., Liu, X., & Davidson, J. (2014). Trace element budgets and (re)distribution during subduction-zone ultrahigh pressure metamorphism: Evidence from Western Tianshan, China. Chemical Geology, 365, 54-68. https://doi.org/10.1016/j.chemgeo.2013.12.005

We have conducted an LA-ICP-MS in situ trace element study of garnet, epidote group minerals, phengitic muscovite and paragonite in rocks of basaltic and sedimentary protolith from an ultrahigh pressure metamorphic belt along Western Tianshan, China....

Maximizing EGS earthquake location accuracies (2014)
Presentation / Conference Contribution
Foulger, G., & Julian, B. (2014). Maximizing EGS earthquake location accuracies. In 39th Workshop on geothermal reservoir engineering : Stanford Geothermal Program Workshop Report SGP-TR-202, Stanford, California, USA, 24-26 February 2014 ; proceedings (902-911)

Uncertainties in local models of seismic wave speed cause two kinds of errors in estimated microearthquake locations. Errors that differ between nearby events, and which degrade the resolution of faults and similar structures, can now be greatly redu... Read More about Maximizing EGS earthquake location accuracies.

Geochemical evidence for relict degassing pathways preserved in andesite (2014)
Journal Article
Plail, M., Edmonds, M., Humphreys, M., Barclay, J., & Herd, R. (2014). Geochemical evidence for relict degassing pathways preserved in andesite. Earth and Planetary Science Letters, 386, 21-33. https://doi.org/10.1016/j.epsl.2013.10.044

Andesitic arc volcanoes degas large quantities of volatiles; evidence for vapour transport in the erupted lavas is rarely preserved and poorly understood, but is crucial for understanding eruption style. We present geochemical evidence for the transp... Read More about Geochemical evidence for relict degassing pathways preserved in andesite.

Time series analysis of the world’s longest fluvial nitrate record: evidence for changing states of catchment saturation (2014)
Journal Article
Worrall, F., Howden, N., & Burt, T. (2014). Time series analysis of the world’s longest fluvial nitrate record: evidence for changing states of catchment saturation. Hydrological Processes, 22(3), 434-444. https://doi.org/10.1002/hyp.10164

Processes that drive the occurrence of nitrate concentrations in surface waters are known to operate over many decades longer than the available observations. This study considers the world's longest water quality record of nitrate concentrations in...

Effect of glass on the frictional behavior of basalts at seismic slip rates (2014)
Journal Article
Violay, M., Di Toro, G., Gibert, B., Nielsen, S., Spagnuolo, E., Del Gaudio, P., …Scarlato, P. (2014). Effect of glass on the frictional behavior of basalts at seismic slip rates. Geophysical Research Letters, 41(2), 348-355. https://doi.org/10.1002/2013gl058601

We performed 31 friction experiments on glassy basalts (GB) and glass-free basalts (GFB) at slip rates up to 6.5 m s−1 and normal stress up to 40 MPa (seismic conditions). Frictional weakening was associated to bulk frictional melting and lubrication... Read More about Effect of glass on the frictional behavior of basalts at seismic slip rates.
