Convergence-aligned, foreland magmatism in the Arabia? Anatolia Collision: Geochronological evidence from the Karacadağ Volcanic Complex, southeast Turkey (2019)
Journal Article
Ekici, T., & MacPherson, C. (2019). Convergence-aligned, foreland magmatism in the Arabia? Anatolia Collision: Geochronological evidence from the Karacadağ Volcanic Complex, southeast Turkey. Turkish journal of earth sciences, 28, 719-733. https://doi.org/10.3906/yer-1902-25

New 40Ar/39Ar ages are presented for volcanic rocks from the Karacadağ Volcanic Complex (KVC) in SE Anatolia. These extend the oldest age recognised for the KVC for lavas from the Siverek Phase plateau basalt back to at least 17 Ma. Our data agree wi...

Along arc heterogeneity in local seismicity across the Lesser Antilles subduction zone from a dense ocean-bottom seismometer network (2019)
Journal Article
Bie, L., Rietbrock, A., Hicks, S., Allen, R., Blundy, J., Clouard, V., …Wilson, M. (2020). Along arc heterogeneity in local seismicity across the Lesser Antilles subduction zone from a dense ocean-bottom seismometer network. Seismological Research Letters, 9(1), 237-247. https://doi.org/10.1785/0220190147

The Lesser Antilles arc is only one of two subduction zones where slow‐spreading Atlantic lithosphere is consumed. Slow‐spreading may result in the Atlantic lithosphere being more pervasively and heterogeneously hydrated than fast‐spreading Pacific l...

Generation of the Mt Kinabalu Granite by Crustal Contamination of Intraplate Magma Modelled by Equilibrated Major Element Assimilation with Fractional Crystallization (EME-AFC) (2019)
Journal Article
Burton-Johnson, A., Macpherson, C., Ottley, C., Nowell, G., & Boyce, A. (2019). Generation of the Mt Kinabalu Granite by Crustal Contamination of Intraplate Magma Modelled by Equilibrated Major Element Assimilation with Fractional Crystallization (EME-AFC). Journal of Petrology, 60(7), 1461-1487. https://doi.org/10.1093/petrology/egz036

New geochemical data are presented for the composite units of the Mount Kinabalu granitoid intrusion of Borneo and utilised to explore the discrimination between crustal- and mantle-derived granitic magmas. The geochemical data demonstrate that the u...

Earth's deepest earthquake swarms track fluid ascent beneath nascent arc volcanoes (2019)
Journal Article
White, L. T., Rawlinson, N., Lister, G. S., Waldhauser, F., Hejrani, B., Thompson, D. A., …Morgan, J. P. (2019). Earth's deepest earthquake swarms track fluid ascent beneath nascent arc volcanoes. Earth and Planetary Science Letters, 521, 25-36. https://doi.org/10.1016/j.epsl.2019.05.048

Most of the world's explosive volcanoes are located in volcanic arcs, formed by fluid-fluxed melting of upper mantle rocks. The fluids that facilitate melting are released from subducted tectonic plates as they sink into the mantle. Yet, we have spar...

Adakites without a slab: Remelting of hydrous basalt in the crust and shallow mantle of Borneo to produce the Miocene Sintang Suite and Bau Suite magmatism of West Sarawak (2019)
Journal Article
Breitfeld, H. T., Macpherson, C., Hall, R., Thirlwall, M., Ottley, C. J., & Hennig-Breitfeld, J. (2019). Adakites without a slab: Remelting of hydrous basalt in the crust and shallow mantle of Borneo to produce the Miocene Sintang Suite and Bau Suite magmatism of West Sarawak. Lithos, 344-345, 100-121. https://doi.org/10.1016/j.lithos.2019.06.016

We present new geochronological and geochemical data for Neogene magmatism from West Sarawak. Zircon U-Pb geochronology divides Neogene magmatic rocks of West Sarawak into a Lower Miocene West Sarawak Sintang Suite with ages of c. 19 to 21 Ma, and a...

Evidence from plutonic xenoliths for magma differentiation, mixing and storage in a volatile-rich crystal mush beneath St. Eustatius, Lesser Antilles (2019)
Journal Article
Cooper, G. F., Blundy, J. D., Macpherson, C. G., Humphreys, M. C., & Davidson, J. P. (2019). Evidence from plutonic xenoliths for magma differentiation, mixing and storage in a volatile-rich crystal mush beneath St. Eustatius, Lesser Antilles. Contributions to Mineralogy and Petrology, 174(5), Article 39. https://doi.org/10.1007/s00410-019-1576-4

Quantifying the storage conditions and evolution of different magmatic components within sub-volcanic plumbing systems is key to our understanding of igneous processes and products. Whereas erupted magmas represent a portion of the eruptible volcanic...
