Plumes, or plate tectonic processes? (2002)
Journal Article
Foulger, G. (2002). Plumes, or plate tectonic processes?. Astronomy and Geophysics, 43(6), 6.19-6.23. https://doi.org/10.1046/j.1468-4004.2002.43619.x

Hotspots – large volcanic provinces – such as Iceland, Hawaii and Yellowstone, are almost universally assumed to come from plumes of hot mantle rising from deep within the Earth. At Iceland, perhaps the best-studied hotspot on Earth, this hypothesis... Read More about Plumes, or plate tectonic processes?.

Imaging the mantle beneath Iceland using integrated seismological techniques (2002)
Journal Article
Allen, R., Nolet, G., Morgan, W., Vogfjörd, K., Bergsson, B., Erlendsson, P., …Stefánsson, R. (2002). Imaging the mantle beneath Iceland using integrated seismological techniques. Journal of Geophysical Research, 107(B12), Article 2325. https://doi.org/10.1029/2001jb000595

Using a combination of body wave and surface wave data sets to reveal the mantle plume and plume head, this study presents a tomographic image of the mantle structure beneath Iceland to 400 km depth. Data comes primarily from the PASSCAL-HOTSPOT depl... Read More about Imaging the mantle beneath Iceland using integrated seismological techniques.

Plume-driven plumbing and crustal formation in Iceland (2002)
Journal Article
Allen, R., Nolet, G., Morgan, W., Vogfjörd, K., Nettles, M., Ekström, G., …Stefánsson, R. (2002). Plume-driven plumbing and crustal formation in Iceland. Journal of Geophysical Research, 107(B8), Article 2163. https://doi.org/10.1029/2001jb000584

Through combination of surface wave and body wave constraints we derive a three-dimensional (3-D) crustal S velocity model and Moho map for Iceland. It reveals a vast plumbing system feeding mantle plume melt into upper crustal magma chambers where c... Read More about Plume-driven plumbing and crustal formation in Iceland.

Crustal structure beneath western and eastern Iceland from surface waves and receiver functions (2002)
Journal Article
Du, Z., Foulger, G., Julian, B., Allen, R., Nolet, G., Morgan, W., …Vogfjord, K. (2002). Crustal structure beneath western and eastern Iceland from surface waves and receiver functions. Geophysical Journal International, 149(2), 349-363. https://doi.org/10.1046/j.1365-246x.2002.01642.x

We determine the crustal structures beneath 14 broad-band seismic stations, deployed in western, eastern, central and southern Iceland, using surface wave dispersion curves and receiver functions. We implement a method to invert receiver functions us... Read More about Crustal structure beneath western and eastern Iceland from surface waves and receiver functions.
