Tectonic setting and timing of the final Deccan flood basalt eruptions (2010)
Journal Article
Hooper, P., Widdowson, M., & Kelley, S. (2010). Tectonic setting and timing of the final Deccan flood basalt eruptions. Geology, 38(9), 839-842. https://doi.org/10.1130/G31072.1

The role of extensional tectonics in the generation of basaltic melt and eruption of continental flood basalts is controversial, and yet it remains crucial to understanding the origin and cause of these large-volume eruptions. Establishing the timing... Read More about Tectonic setting and timing of the final Deccan flood basalt eruptions.

Tectonic history and occurrence of 2.4 Ga mafic dyke swarms adjacent to Godavari Basin, Karimnagar, India (2010)
Journal Article
Mallikharjuna Rao, J., Poornachandra Rao, G. V., Widdowson, M., Yellappa, T., & Kelley, S. P. (2010). Tectonic history and occurrence of 2.4 Ga mafic dyke swarms adjacent to Godavari Basin, Karimnagar, India. Current Science, 98(11), 1472-1478

Proterozoic dyke swarms are exposed partly in granulitic terrain and partly in gneissic terrain and extend in a NE-SW direction near the Godavari Basin, Karimnagar area, Central India. The Karimnagar dyke swarm petrographically exhibits two groups su... Read More about Tectonic history and occurrence of 2.4 Ga mafic dyke swarms adjacent to Godavari Basin, Karimnagar, India.

Journal Article
Sun, Y., Lai, X., Wignall, P. B., Widdowson, M., Ali, J. R., Jiang, H., Wang, W., Yan, C., Bond, D. P., & Védrine, S. (2010). Dating the onset and nature of the Middle Permian Emeishan large igneous province eruptions in SW China using conodont biostratigraphy and its bearing on mantle plume uplift models. Lithos, 119(1-2), 20-33. https://doi.org/10.1016/j.lithos.2010.05.012

The Middle Permian Emeishan large igneous province of SW China has provided the quintessential example of the phenomenon of kilometre-scale pre-eruption domal uplift associated with mantle plume impingement on the base of the lithosphere. One key lin...

New 40Ar/39Ar dating of the Grande Ronde lavas, Columbia River Basalts, USA: Implications for duration of flood basalt eruption episodes (2010)
Journal Article
Barry, T. L., Self, S., Kelley, S. P., Reidel, S., Hooper, P., & Widdowson, M. (2010). New 40Ar/39Ar dating of the Grande Ronde lavas, Columbia River Basalts, USA: Implications for duration of flood basalt eruption episodes. Lithos, 118(3-4), 213-222. https://doi.org/10.1016/j.lithos.2010.03.014

Grande Ronde Basalt (GRB) lavas represent the most voluminous eruptive pulse of the Columbia River-Snake River-Yellowstone hotspot volcanism. With an estimated eruptive volume of 150,000km3, GRB lavas form at least 66% of the total volume of the Colu...
