Lithosphere highlights: Slab dynamics, the Troodos ophiolite, and the Jurassic Bonanza arc
Date:11/15/2012

ging from plumes to lithospheric drips and subducted slab fragments. Varied interpretations of such structures motivate a better understanding of the geometric, compositional, rheologic, and dynamic conditions inside the upper mantle from which they might originate. In the dynamic numerical models presented here, E. Burkett and M. Gurnis focus in particular on testing conditions that affect how long a stalled subducted piece of a lithospheric plate may remain dangling in the upper mantle before breaking off and sinking, as motivated by interpretations of a structure beneath Idaho as a remnant of the previously subducted Farallon plate left dangling for more than 40 million years.


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.
