A tract of amphibolite facies granitic gneisses and metagabbros in northern Shetland, U.K., is here named the Uyea Gneiss Complex. Zircon U–Pb dating indicates emplacement of the igneous protoliths of the complex c. 2746–2726 Ma, at a later time than...

Ash aggregation is a common phenomenon in particle-laden environments of volcanic eruption plumes and pyroclastic density currents. Many of these initially fragile aggregates gain sufficient mechanical strength to remain intact after atmospheric tran...

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., Tanner, D., Macpherson, C. G., Tkalčić, H., & Morgan, J. P. (2019).

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...

Zircon is an important accessory mineral for studying the crust-mantle interaction and crustal growth through time because zircon crystals not only allow precise dating but also record initial Hf isotope ratios of the host magmas. Our study on a suit... Read More about Discrepancy between bulk-rock and zircon Hf isotopes accompanying Nd-Hf isotope decoupling.

The species of the brachiopod Gigantoproductus are giants within the Palaeozoic sedentary benthos. This presents a dilemma as living brachiopods have low‐energy lifestyles. Although brachiopod metabolic rates were probably higher during the Palaeozoi... Read More about The giants of the phylum Brachiopoda: a matter of diet?.
