Introduction: Origin and Evolution of the Sierra Nevada and Walker Lane

Putirka, Keith D.; Busby, Cathy J. (Geological Society of America, 12/1/2011)
Cenozoic volcanism in the Sierra Nevada and Walker Lane, California, and a new model for lithosphere degradation

Putirka, Keith D.; Jean, Marlon; Cousens, Brian; Sharma, Rohit; Torrez, Gerardo; Carlson, Chad (Geological Society of America, 4/1/2012)

Volcanic rock and mantle xenolith compositions in the Sierra Nevada (western United States) contradict a commonly held view that continental crust directly overlies asthenosphere beneath the Sierran range front, and that ...
Basin and Range volcanism as a passive response to extensional tectonics

Putirka, Keith D.; Platt, Bryant (Geological Society of America, 10/18/2012)

A long-standing issue in Cordilleran geology involves the nature of Basin and Range (western USA) volcanism, and whether such magmatism provides a trigger for extensional deformation, or if volcanic activity is a passive ...
Formation of the Sierra Nevada batholith: magmatic and tectonic processes and their tempos

Paterson, Scott R.; Lackey, Jade Star; Memeti, Vali; Miller, Robert B.; Miller, Jonathan S.; Mundil, Roland; Putirka, Keith D. (Geological Society of America, 2012-09)

The article focuses on the Geological Society of America (GSA) Penrose Field Forum held in Sierra Nevada in California and Nevada from September 1-8, 2012. The forum aimed at understanding the magmatic and tectonic processes ...
Mantle potential temperatures at Hawaii, Iceland, and the mid-ocean ridge system, as inferred from olivine phenocrysts: Evidence for thermally driven mantle plumes

Putirka, Keith D. (American Geophysical Union (AGU)Geochemical Society, 2005)

Temperature differences between lavas erupted at ocean islands and mid-ocean ridges are crucial to documenting the existence of mantle plumes. Olivines are useful for T estimation because they provide a less homogenized ...
