Haven't checked in here in a long time - seeing as my last post was over 2 months ago. The summer has been a whirlwind: first there was CIDER at UC Berkeley for 3 weeks, then a week in the field looking at pluton-wall rock interactions, skarns, and copper porphyries in Southern California and Nevada, then a few weeks back at Rice tidying up my paper for resubmission to JPet, and then the Goldschmidt Conference in Prague, Czech Republic.
Goldschmidt was a great conference, it was a good experience to see what the latest developments in the field of geochemistry were, as well as present my own work to the community. There were lots of interesting talks, here are some of the highlights. In the session on role of continental/island arcs in crust formation, there were several talks similar to mine, which instead of looking at crustal input beneath arcs from the continent-ward side, examined the material coming in from the subducting slab side:
delta 18O and how it might be used to estimate how much supracrustal material gets into the deep crust beneath arcs (Lackey), "relamination" mechanisms and how these might be related to UHP rocks (Kelemen at al.). I also went to several Keynote talks which were really good, particularly Ionov's talk on the Siberian craton. There was also an entire session on rutile and what we can now do with it for thermobarometry in light of new experiments. There was a whole session on crustal growth models, which was packed! I also sat in on some radiogenic isotope geochemistry sessions, during one of them the talk evolved into a shouting match.
On Sunday before the conference started, I had a chance to do a little exploration of the city. Prague is beautiful. It's truly a "textbook" of architecture, where you can see so many styles and old to modern buildings that are extremely well preserved. There were many things I loved about Prague. One was how much detail is packed in everywhere you look - the city is actually quite small, you can walk all around it in a day, but everywhere you turn you need to look twice to take in all the beautiful architectural details. I loved all the amazing Art Nouveau structures, such as the balconies and doorways:
Another thing I loved about Prague was how there are gardens everywhere throughout the city. Even in the main square, there's little patches of lawn and rows of roses, lavender, and other flowers. Wandering through the city, you find yourself walking through a passageway that you have no idea where it leads, but suddenly opens up into a little secluded garden with well-tended hedges and roses.

Even the bus stations are natural, with grass and flowers allowed to bloom and grow like they should.
Walking around the city there are tons of Bohemian crystal shops everywhere, with incredibly ornate, bejeweled goblets and crockery (they are really into crockery here in the Czech republic... even the water glasses and light bulb covers in our barebones dorm room were crockery). I found this tiny little "souvenir shop" tucked away in a corner on a cobblestone street:
Some native Czech arts and crafts.
While attending Goldschmidt, I stayed in a dorm along with other students, located on the outskirts of the city (but it was extremely easy to get into Prague since the public transport was so close and fast). The area by the dorms was quite natural, right near the river, and with lots of trees and fields around. A few nights it rained, and the morning afterward, all the slugs and one beautiful snail came out from the woods to hang out on the sidewalk. There was a pear tree nearby which had dropped a number of pears, which began to rot and ferment on the ground - this became a feast for the slugs. Walking to the bus stop each morning, I passed by tons of slugs just feasting on the rotting pears. Some of the slugs were enormous! I identified them as Arion rufus, the European red slug (native to Europe). Check out the huge pneumostome (breathing pore) on some of these guys:
Amidst all the slugs, there was only one snail, but he was huge (about the size of a crabapple):
Seeing this snail every day made me very happy for some reason. I don't know why, but I find snails fascinating. Maybe it's how their locomotion works - they slime the ground and then ripple their giant foot. And then their shells are beautiful too, and so are their bodies, which if you look really closely are translucent and seem to shimmer sometimes. OK, that's it for now. More posts later about our field work in Southern California. It's much easier adjusting to the time change going from Europe to North America, than the other way around. It's amazing that just yesterday I was on another continent!
