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

ain the timing of rifting of the supercontinent Rodinia. Joshua A. Keeley and colleagues employ several U-Pb zircon dating techniques and provide the first ~700-million-year-old zircon lutetium-hafnium isotopic data from western Laurentia. This work is part of a larger body of emerging research on Neoproterozoic stratigraphy in the western U.S. that has implications for Cordillera-wide and global paleogeographic reconstructions.


Geochemistry and geochronology of the Troodos ophiolite: An SSZ ophiolite generated by subduction initiation and an extended episode of ridge subduction?
S. Osozawa et al., Dept. of Earth Sciences, Graduate School of Science, Tohoku University, Sendai, 980-8578, Japan. Posted online 14 Nov. 2012; http://dx.doi.org/10.1130/L205.1.

Soichi Osozawa and colleagues present new trace-element, radiogenic isotopic, and geochronologic data from the Troodos ophiolite, along with a large body of previously published data, that give new insight into the tectonic history of this storied ophiolite. The data also demonstrate the variability of suprasubduction-zone ophiolites, as well as differences between them and commonly used modern analogs. Post-analysis, Osozawa and colleagues propose that Troodos was formed over a newly formed subduction zone, similar to many proposed models, and that the extended period of magmatism (boninitic) resulted from a prolonged period of ridge subduction.
