Public Geology Lectures on the Second Friday of the Month
Convenient $5 evening parking is available after 5:00 p.m. in Parking Structure #2, 1724 SW Broadway, across from Cramer Hall. Note your license plate, so you can enter it and pay at the pay station. More PSU parking info here.
Join us at 6:00 p.m. at Pizzicato, 1708 SW 6th Avenue for delicious pizza and salads and beverages.
Join us in down the hall in the Geology Department office for snacks and discussion. Also check out our lending library in Room 69 staffed by Librarian Diane Gordon.
For People Using Public Transportation
Look for a convenient park and ride near a MAX train or bus stop. The #19 bus and the Orange Line MAX drop you off within a block or two of PSU. The bus gets scarce after 9:00 but MAX runs pretty frequently.
Lecture in Cramer Hall
Join us for lectures on topics of geologic interest. All GSOC lectures are open to the public. A $3 donation is requested. (Free for students.) Snacks are available after the lecture in the Geology Department Office, 17 Cramer Hall.
Jon Krier, MA Archeology at University of Oregon will be discussing his work on coastal paleoland forms. In 2016, in a collaboration between OSU and the Confederated Tribes of Grand Ronde, a new set of coastline change models for the last 20,000 years were developed. The goal of the project was twofold: First, the straightforward goal was to get a clearer picture of how the Oregon and Washington coastlines had changed since the Last Glacial Maximum in light of newly developed digital elevation models that incorporated isostatic adjustments.
Progress report on an integrated study of an Eocene subtropical shelf-margin delta, Coos Bay, Oregon
The Middle to Late Eocene Coaledo Formation and underlying Beds of Sacchi Beach record a marine history of forearc sedimentation. The sediments aggrade from slope turbidites to shoreface deltaic sandstone encased in deep-water silty mudstone. This talk is a progress report on a multiyear, multidiscipline research program, testing the hypothesis that the Sacchi Beach-Coaledo succession represents a shelf-margin lowstand of sealevel deltaic system. A team of 12 geoscientists is collecting an interdisciplinary database for reassessing the depositional history of the rocks exposed along the Cape Arago, Shore Acres and Sunset Bay State Parks.
PSU Geology doctoral candidate Vanessa Swenton will discuss her research investigating some of the volcanic eruptions that occurred in eastern Oregon approximately 16 million years ago (Ma) to present day. There are two dominant volcanic provinces that have had episodes of high-silica (silicic/felsic) volcanism in eastern Oregon. The older episode is known to be associated with the Yellowstone mantle plume and Columbia River Basalt Group volcanism. The younger episode is within the High Lava Plains, and it is debated as being solely a result of the initial Yellowstone plume, or as a result of Cascadia slab rollback processes.
Lectures are in Cramer Hall, Portland State University, 1721 SW Broadway; between Montgomery and Mill. Room assignments vary, so check our latest announcement.
