From basalts to boninites: The geodynamics of volcanic expression during induced subduction initiation
W. Leng et al., Seismological Laboratory, California Institute of Technology, Pasadena 91125, California, USA. Posted online 26 Oct. 2012; http://dx.doi.org/10.1130/L215.1.
Subduction initiation is induced at the interfaces of adjacent plates. This dynamic process is accompanied by different evolutionary pathways, including plate breakup, volcanic eruptions and topography changes. W. Leng and colleagues use numerical models and geochemical data to explain the causes for these different evolutionary pathways, and conclude that the physical properties of the lithosphere are the key point for the process. This result helps people to better understand the divergent history of various subduction zones.
