I will do this using whole rock radiogenic isotope geochemistry and high-precision U-Pb zircon geochronology acquired by chemical abrasion-isotope dilution-thermal ionization mass spectrometry (CA-ID-TIMS) in the Denver Radiogenic Isotope Lab.Prior to joining the USGS, I spent three years working in the Bowring Isotope Laboratory at MIT. There, I primarily performed U-Pb zircon CA-ID-TIMS analyses to 1) understand chronostratigraphy of the Permian-Triassic Karoo Basin of South Africa; 2) determine the timing of magmatism and deformation in the Scottish Caledonides, and 3) unravel the magmatic history of the early Paleozoic Rye Complex of New Hampshire and Maine. Prior to that, I completed my M.S. and Ph.D. at UNC\u2013Chapel Hill, studying the rates and sources of magmatism in the central Sierra Nevada, CA and the Grizzly Peak magmatic system, CO, particularly with respect to the links between plutonic and volcanic rocks, supervolcano eruptions, and the tectonic history of magmatic arcs. I first became interested in the geology and geochemistry of the Sierra Nevada through undergraduate research at Pomona College." } ], "email": "rfrazer@usgs.gov", "url": "https://www.usgs.gov/staff-profiles/ryan-e-frazer", "affiliation": [], "hasCredential": [ { "@type": "EducationalOccupationalCredential", "name": "Ph.D., Geological Sciences, University of North Carolina at Chapel Hill (2017)" }, { "@type": "EducationalOccupationalCredential", "name": "M.S., Geological Sciences, University of North Carolina at Chapel Hill (2013)" }, { "@type": "EducationalOccupationalCredential", "name": "B.A., Geology, Pomona College (2009)" } ], "knowsAbout": [ { "@type": "Thing", "additionalType": "self-claimed expertise", "name": "Isotope Geochemistry" }, { "@type": "Thing", "additionalType": "self-claimed expertise", "name": "Geochronology" }, { "@type": "Thing", "additionalType": "self-claimed expertise", "name": "Igneous Petrology" } ], "memberOf": { "@type": "OrganizationalRole", "name": "staff member", "member": { "@type": "Organization", "name": "U.S. Geological Survey" }, "startDate": "2024-09-21T07:55:33.113798" } }, "ORCID": { "@context": "http://schema.org", "@id": "https://orcid.org/0000-0002-7319-1894", "@reverse": { "creator": [ { "@id": "https://doi.org/10.2138/am-2022-8503", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.2138/am-2022-8503" }, "name": "Fluorine-rich mafic lower crust in the southern Rocky Mountains: The role of pre-enrichment in generating fluorine-rich silicic magmas and porphyry Mo deposits" }, { "@id": "https://doi.org/10.2113/2022/5511120", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.2113/2022/5511120" }, "name": "Insights from the Alabama Hills into Mesozoic Magmatism and Tectonics in Eastern California" }, { "@id": "https://doi.org/10.1016/j.jafrearsci.2021.104435", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1016/j.jafrearsci.2021.104435" }, "name": "U-Pb zircon age constraints on the vertebrate assemblages and palaeomagnetic record of the Guadalupian Abrahamskraal Formation, Karoo Basin, South Africa" }, { "@id": "https://doi.org/10.1130/abs/2021am-367761", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2021am-367761" }, "name": "Magmatic history of the Grizzly Peak caldera, Sawatch Range, Colorado" }, { "@id": "https://doi.org/10.1130/abs/2021cd-362974", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2021cd-362974" }, "name": "Modern deformation and volcanism in Owens Valley reactivates a Laramide-age shear zone" }, { "@id": "https://doi.org/10.1130/abs/2021cd-362988", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2021cd-362988" }, "name": "The Alabama Hills and dextral offset in Owens Valley, CA" }, { "@id": "https://doi.org/10.1144/jgs2020-039", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1144/jgs2020-039" }, "name": "Patterns of Silurian deformation and magmatism during sinistral oblique convergence, northern Scottish Caledonides" }, { "@id": "https://doi.org/10.1130/abs/2020cd-347096", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2020cd-347096" }, "name": "DEXTRAL OFFSET ACROSS OWENS VALLEY: A VIEW FROM THE ALABAMA HILLS TO THE COSO RANGE" }, { "@id": "https://doi.org/10.1130/abs/2020cd-346659", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2020cd-346659" }, "name": "MODERN DEFORMATION AND VOLCANISM IN OWENS VALLEY REACTIVATES A LARAMIDE-AGE SHEAR ZONE" }, { "@id": "https://doi.org/10.1130/abs/2019ne-328272", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2019ne-328272" }, "name": "RYE ON THE SHOALS -
