    Introduction: Origin and Evolution of the Sierra Nevada and Walker Lane (2011)
    Geological Society of America (GSA)
    Details
    Publication Date: 2011-12-01
    Description: This Geosphere themed issue is an outgrowth of our Penrose Conference: Origin and Uplift of the Sierra Nevada, California, which was held in Bridgeport, California, August 16–20, 2010. The theme is here expanded to include the Walker Lane (Fig. 1), since a large number of our Penrose abstracts were oriented to that topic, and because that region is no less a part of the Sierran story than the high peaks themselves. A fundamental question for the conference and themed issue is “How did the Sierra Nevada form?” The question can mean many things to disparate disciplines. One might refer to the age and origin of the rocks that form the Sierra Nevada batholith, or instead to the time at which such rocks were uplifted to form the topographic crest of the eastern Sierra. One might also speak to the origin of canyons and peaks formed by erosion as much as uplift, or to the time at which the Sierra's varied present-day ecological zones were established. The answers to these questions can be quite different, but are not necessarily independent, as insights from one may lend insight to another. Finally, the complete story of the Sierra also cannot be told without the tectonic forces that act on the Sierran crust, which involves the evolution of the San Andreas Fault system and the opening of the Gulf of California.

    An improved clinopyroxene-based hygrometer for Etnean magmas and implications for eruption triggering mechanisms (2020)
    Details
    Publication Date: 2020-02-07
    Description: We have refined the clinopyroxene-based hygrometer published by Armienti et al. (2013) for a better quantitative understanding of the role of H2O in the differentiation of Etnean magmas. The original calibration data set has been significantly improved by including several experimental clinopyroxene compositions that closely reproduce those found in natural Etnean products. To verify the accuracy of the model, some randomly selected experimental clinopyroxene compositions external to the calibration data set have been used as test data. Through a statistic algorithm based on the Mallows' C-P criterion, we also check that all model parameters do not cause data overfitting, or systematic error. The application of the refined hygrometer to the Mt. Etna 2011-2013 lava fountains indicates that most of the decreases in H2O content occur at P 〈 100 MPa, in agreement with melt inclusion data suggesting abundant H2O degassing at shallow crustal levels during magma ascent in the conduit and eruption to the surface.
