The “gold st andard” for geochronology is uranium-lead (U-Pb) dating of the mineral z ircon. In this talk\, I shall review the current state of the art for zirc on U-Pb geochronology. I shall then present an example from my own work sh owing how high-precision U-Pb dating can be used to study plate tectonic p rocesses. Subduction zones are a key piece of the plate tectonic cycle\, w here old oceanic crust is recycled back into the Earth’s mantle\, and ne w crust is formed from the resulting magmatism. I shall present new data f rom work I have done in Oman\, where combined high-precision dating and ge ochemical analyses provide new insight into the initiation of a new subduc tion zone\, a critical\, but poorly understood\, component of plate tecton ics.\n\nSpeaker(s): Matt Rioux\, \n\nRoom: Event Room\, Rusty's Pizza\, 59 34 Calle Real\, Goleta\, California\, United States\, 93117\, Virtual: htt ps://events.vtools.ieee.org/m/512963 LOCATION:Room: Event Room\, Rusty's Pizza\, 5934 Calle Real\, Goleta\, Cali fornia\, United States\, 93117\, Virtual: https://events.vtools.ieee.org/m /512963 ORGANIZER:rfranklin.ieee@gmail.com SEQUENCE:111 SUMMARY:IEEE CENTRAL COAST FREE EVENT 19 NOVEMBER 6PM @ RUSTY'S URL;VALUE=URI:https://events.vtools.ieee.org/m/512963 X-ALT-DESC:Description: <br /><p class="MsoNormal" style="margin-bottom: 6. 0pt\; line-height: normal\;"><strong><em><span style="font-family: 'Arial' \,sans-serif\;">Abstract:</span></em></strong><span style="font-family: 'A rial'\,sans-serif\;"> To understand the timing and rates of geological pro cesses\, it is necessary to precisely date geologic events. <span style="m so-spacerun: yes\;">&nbsp\;</span>The &ldquo\;gold standard&rdquo\; for ge ochronology is uranium-lead (U-Pb) dating of the mineral zircon.
