Eruption of kimberlite magmas: physical volcanology, geomorphology and age of the youngest kimberlitic volcanoes known on earth (the Upper Pleistocene/ Holocene Igwisi Hills volcanoes, Tanzania) (2012)
Journal Article
Brown, R., Manya, S., Buisman, I., Fontana, G., Field, M., Niocaill, C., …Stuart, F. (2012). Eruption of kimberlite magmas: physical volcanology, geomorphology and age of the youngest kimberlitic volcanoes known on earth (the Upper Pleistocene/ Holocene Igwisi Hills volcanoes, Tanzania). Bulletin of Volcanology, 74(7), 1621-1643. https://doi.org/10.1007/s00445-012-0619-8

The Igwisi Hills volcanoes (IHV), Tanzania, are unique and important in preserving extra-crater lavas and pyroclastic edifices. They provide critical insights into the eruptive behaviour of kimberlite magmas that are not available at other known kimb...

A review of volcanic ash aggregation (2012)
Journal Article
Brown, R., Bonadonna, C., & Durant, A. (2012). A review of volcanic ash aggregation. Physics and Chemistry of the Earth, Parts A/B/C, 45-46, 65-78. https://doi.org/10.1016/j.pce.2011.11.001

Most volcanic ash particles with diameters <63 μm settle from eruption clouds as particle aggregates that cumulatively have larger sizes, lower densities, and higher terminal fall velocities than individual constituent particles. Particle aggregation...

The origin of pelletal lapilli in explosive kimberlite eruptions (2012)
Journal Article
Gernon, T., Brown, R., Tait, M., & Hincks, T. (2012). The origin of pelletal lapilli in explosive kimberlite eruptions. Nature Communications, 3, Article 832. https://doi.org/10.1038/ncomms1842

Kimberlites are volatile-rich magmas from mantle depths of ≥150 km and are the primary source of diamonds. Kimberlite volcanism involves the formation of diverging pipes or diatremes, which are the locus of high-intensity explosive eruptions. A consp...
