Prized Writing, published by the University Writing Program, or UWP, in the College of Letters and Science, showcases nonfiction works by undergraduates in disciplines all across campus. James "Huck" Rees, who graduated in 2018 with a degree in geology, is featured in Prized Writing (2019-2020).
From GeoSpace: "Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth’s crust, offering a window into the building blocks of our planet, according to new research. The new study in the AGU Journal Geochemistry, Geophysics, Geosystems used models to trace the location and origin of volcanic rock samples found throughout the world back to two solid continents in the deep mantle. The new research suggests the specific giant rock regions have existed for 4.5 billion years, since Earth’s beginning." Curtis Williams is lead author of the study, with Sujoy Mukhopadhyay, Max Rudolph and Barbara Romanioqicz (UC Berkeley).
Mike Oskin | 2019 Best Paper Award, GSA Structure and Tectonics Division
A 2016 paper co-authored by Mike Oskin, John Fletcher and Orlando Teran (Fletcher et al., 2016) will be honored with the 2019 Best Paper Award at the Structure and Tectonics Division meeting during the GSA 2019 Annual Meeting. This paper laid out what they call the 'Keystone Fault Hypothesis' for control of crustal stress, inspired by faulting and aftershock data from the 2010 El Mayor-Cucapah Earthquake.
Researchers present a new paradigm for understanding how pressures in planets evolve. "Previous studies have incorrectly assumed that a planet's internal pressure is simply a function of the mass of the planet, and so it increases continuously as the planet grows. What we've shown is that the pressure can temporarily change after a major impact, followed by a longer term increase in pressure as the post-impact body recovers. This finding has major implications for the planet's chemical structure and subsequent evolution," says Simon Lock, postdoctoral researcher at Caltech and lead author of a paper explaining the new model that was published by Science Advances. Lock authored the paper with colleague Sarah Stewart.
The Gilbert Harris Award is given annually by the Paleontological Research Institution, in recognition of excellence in contributions to systematic paleontology, to a scientist who, through outstanding research and commitment to the centrality of systematics in paleontology, has made a significant contribution to the science. The award will be presented to Sandy Carlson at the annual Friends of PRI reception at the annual meeting of the Geological Society of America on Monday, September 23 at 5:30 pm in Phoenix.
From Sierra Club: : What ancient coral can tell us about climate change. The field of paleoclimatology—the study of past climate change on our planet—is booming. For Dr. Hill, the most critical answers are still waiting to be discovered.
I study how Earth’s atmosphere got its oxygen. Take a deep breath and appreciate those bacteria that evolved photosynthesis billion of years ago!i am a geobiologist.
