Dorsey Wanless Research
My research interests lie in understanding how magmas evolve from generation in the mantle, to storage within the crust, and finally, eruption at the Earth’s surface. I use a wide range of geochemical tracers including: major and trace element compositions, radiogenic, helium, and oxygen isotopes ratios, and volatile concentrations, in combination with petrologic modeling to understand how fractional crystallization, assimilation of crustal rocks, melt-rock reaction, and partial melting can affect the composition of lavas erupted at the surface.
My research has primarily focused on the evolution of magmas in submarine settings including mid-ocean ridges and ocean islands. I am also working on understanding the role of magmatism in continental rifting.
