Mineral King valley in California.
Well, we are in the peak of the summer, so Eruptions will be running a bit of summer schedule while I'm off away from the interweb tubes. First off, from July 11-20, I'll be off in the mountains, doing some much-needed fieldwork with my (first) undergraduate research student. We'll be up in the Mineral King area of Sequoia National Park looking at some old rhyolites and granites - we're talking Triassic and Jurassic submarine and subaerial calderas! We'll hopefully be taking a look at zircons in these rocks to help constrain the timescales of these enigmatic early "Sierran" volcanics (all as a part of a larger Keck Project).
While I'm out in the field, look for some posts that will show up (hopefully automatically): - Guest blogger Dr. Ed Kohut will give us a tour of the Mariana Islands and magma genesis in that volcanic arc. - A new Eruptions Word of the Day. - Mystery volcano photos that will hopefully stump more of you. - And an open thread for you to post in case something exciting happens ... or to discuss whatever volcanic topics catch your fancy.
Enjoy the summer while I'm out in the rocks ... !
