This will be the 451st meeting since 1954
Broad temporal coincidence between select Phanerozoic instances of mass extinction and large igneous province (LIP) magmatism has led many to hypothesize a causal link between the two. Testing the plausibility of this connection depends on the tempo of both and their relative timing. Thus, dating the records of mass extinction and magmatism with the maximum possible precision and accuracy is critical. This presentation will detail the application of U/Pb thermal ionization mass spectrometry (TIMS) geochronology to (1) volcanic ash beds intercalated with the fossil record of the end-Permian mass extinction, and (2) lava flows, sills, and pyroclastic rocks of the Siberian Traps LIP. New dates permit a revised calculation of the tempo of magmatism and mass extinction and allow resolution of their relative timing.
Seth Burgess was raised in northern California in the once sleepy town of Healdsburg. Seth attended Cal Poly San Luis Obispo for an undergraduate in Soil Science, and San José State University for a master's in Geology. Seth completed his Ph.D. work in the Spring of 2014 in the Isotope Geochemistry lab at Massachusetts Institute of Technology. He is now a Mendenhall Postdoctoral fellow at the U.S. Geologic Survey Volcano Science Center in Menlo Park, Calif.
Reservations: The preferred way to make reservations is simply to email Mike Diggles at email@example.com by Feb. 8, tell him you will attend, commit to pay, and bring your payment to the meeting. Mike always emails a confirmation; if you don’t get one, assume email crashed yet again and email him a second time. A check made to “PGS” is preferred, payable at the meeting.
If you want to pay in advance:
Everyone (including Stanford folks now) Please make dinner reservations by Feb. 8. Contact Mike Diggles, at U.S. Geological Survey, 345 Middlefield Road, MS-910 Menlo Park, CA 94025, Tel.: (650) 329-5404. Send check made out to “PGS” to Mike.
Dinner and the social hour is $35.00; this includes $5 that we use to help pay for students who are only $8.00 (also partially subsidized thanks to the School of Earth Sciences, Stanford University (Note, no-show reservations owe the full price).
Doris, whose wonderful crew prepares our meals, asked that we let you know that people who are late RSVPing and people who show up without a reservation will be welcome but that they may be eating on paper plates with plastic utensils (food supply permitting).
Dues for Academic Year 2014-2015 ($10.00) should be sent to Mike Diggles, U.S. Geological Survey, 345 Middlefield Road, MS-910, Menlo Park, CA 94025. Mike’s phone: (650) 329-5404.
