The 56 ka Monte Epomeo Green Tuff (MEGT) resulted from the largest volume explosive eruption from Ischia island (south Italy). Its tephra is one of the main stratigraphic markers of the central Mediterranean area. Despite its importance, a detailed c...

Rapid eruptive transitions from low to high intensity explosions and effusive activity: insights from textural analysis of a small-volume trachytic eruption, Ascension Island, South Atlantic (2021)
Journal Article
Davies, B. V., Brown, R. J., Barclay, J., Scarrow, J. H., & Herd, R. A. (2021). Rapid eruptive transitions from low to high intensity explosions and effusive activity: insights from textural analysis of a small-volume trachytic eruption, Ascension Island, South Atlantic. Bulletin of Volcanology, 83(9), Article 58. https://doi.org/10.1007/s00445-021-01480-1

Proximal deposits of small-volume trachytic eruptions are an under-studied record of eruption dynamics despite being common across a range of settings. The 59 ± 4 ka Echo Canyon deposits, Ascension Island, resulted from a small-volume explosive-effus...

Origins of olivine in Earth’s youngest kimberlite: Igwisi Hills volcanoes, Tanzania craton (2021)
Journal Article
Shaikh, A. M., Tappe, S., Bussweiler, Y., Vollmer, C., Brown, R. J., & EIMF. (2021). Origins of olivine in Earth’s youngest kimberlite: Igwisi Hills volcanoes, Tanzania craton. Contributions to Mineralogy and Petrology, 176(8), Article 62. https://doi.org/10.1007/s00410-021-01816-2

Monomineralic millimeter-sized olivine nodules are common in kimberlites worldwide. It is generally thought that such ‘dunitic nodules’ originate from the base of the cratonic lithosphere and that their formation marks the onset of deep-rooted kimber...
