Ernst, W.G., 2015, Franciscan geologic history constrained by tectonic/olistostromal high-grade metamafic blocks in the iconic California Mesozoic-Cenozoic accretionary complex: American Mineralogist, v. 100, p. 6-13.Â doi:Â 10.2138/am-2015-4850
- This source supplies useful information on the low temperature, high pressure environment in which these rocks formed.Â
Barnes, J., Eldam, R., Lee, C.T., Errico, J., Loewy, S., and Cisneros, M., 2013, Petrogenesis of serpentinites from the Franciscan Complex, western California, USA: Lithos, v. 178, p. 143-157.Â doi:10.1016/j.lithos.2012.12.018
- Describes the petrogenesis of serpentine as seen in one of the items in the collection (Fr-4).
Cooper, F., Platt, J., and Anczkiewicz, R., 2011, Constraints on early Franciscan subduction rates from 2-D thermal modeling: Earth and Planetary Science Letters, v. 312, p. 69-79. doi:10.1016/j.epsl.2011.09.051
- This paper suggests that the rate of subduction in this area may have been five times lower than previous studies have found.
Ghatak, A., Basu, A., and Wakabayashi, J., 2013, Implications of Franciscan Complex graywacke geochemistry for sediment transport, provenance determination, burial-exposure duration, and fluid exchange with cosubducted metabasites: Tectonics, v. 32, p. 1480-1492. doi:Â 10.1002/tect.20078
- This article states that the europium anomalies of the greywacke samples suggest provenance from the Sierra Nevada batholith.
