Podiform chromitites from the Ballantrae Ophiolite Complex (BOC), NW Scotland, are examined to investigate their petrogenesis and elucidate the nature of melt percolation in the supra-subduction zone oceanic mantle more generally. The mantle portion... Read More about Chromitite petrogenesis in the mantle section of the Ballantrae Ophiolite Complex (Scotland).

Advancing Santorini’s tephrostratigraphy: new glass geochemical data and improved marine-terrestrial tephra correlations for the past ~360 kyrs (2019)

The island of Santorini in the Aegean Sea is one of the world’s most violent active volcanoes. Santorini has produced numerous highly explosive eruptions over at least the past ~360 kyrs that are documented by the island’s unique proximal tephra reco...

Crustal CO2 contribution to subduction zone degassing recorded through calc-silicate xenoliths in arc lavas (2019)
Journal Article
Whitley, S., Gertisser, R., Halama, R., Preece, K., R. Troll, V., & M. Deegan, F. (2019). Crustal CO2 contribution to subduction zone degassing recorded through calc-silicate xenoliths in arc lavas. Scientific reports, https://doi.org/10.1038/s41598-019-44929-2

Interaction between magma and crustal carbonate at active arc volcanoes has recently been proposed as a source of atmospheric CO2, in addition to CO2 released from the mantle and subducted oceanic crust. However, quantitative constraints on efciency... Read More about Crustal CO2 contribution to subduction zone degassing recorded through calc-silicate xenoliths in arc lavas.

Eruptive history of the Late Quaternary Ciomadul (Csomád) volcano, East Carpathians, part II: magma output rates (2019)

Located at the southern tip of the Intra-Carpathian Volcanic Range in Romania, and composed of a dozen dacitic lava domes, the Ciomadul (Csomád) volcanic complex is the youngest eruptive centre of the Carpatho-Pannonian Region. Whereas, in the last d... Read More about Eruptive history of the Late Quaternary Ciomadul (Csomád) volcano, East Carpathians, Part I: Timing of lava dome activity.

Magmatic evolution and textural development of the 1739 CE Pietre Cotte lava flow, Vulcano, Italy (2019)
Journal Article
Bullock, L. A., Gertisser, R., O'Driscoll, B., & Harland, S. (2019). Magmatic evolution and textural development of the 1739 CE Pietre Cotte lava flow, Vulcano, Italy. Journal of Volcanology and Geothermal Research, 372, 1-23. https://doi.org/10.1016/j.jvolgeores.2019.01.017

Textural evidence from occurrences of mingled magmas in lava flows often yields insights into chemical and thermal disequilibrium between multiple magma batches at depth. An understanding of these interactions is key as they can occur on short timesc... Read More about Magmatic evolution and textural development of the 1739 CE Pietre Cotte lava flow, Vulcano, Italy.
