More specifically, his wok focuses on the geology of rare earth element (REE) deposits, the behavior of REE in fluids and carbonatite magmas, and mineral resources associated with Paleogene magmatism across western North America. Allen also maintains interest in the formation of magmatic ore deposits enriched in platinum-group elements, chromium, nickel, copper, cobalt, titanium, and vanadium. Prior to joining the USGS, he spent more than six summers as a consulting geologist in the mineral exploration industry.Current Projects2019\u2013Present: Critical Elements in Carbonatites: From Exploration Targets to Element Distribution2018\u2013Present: Critical Commodity Studies, Stillwater Complex, Montana2019\u2013Present: Mineral Resource Assessment Training (Tungsten)" } ], "email": "akandersen@usgs.gov", "url": "https://www.usgs.gov/staff-profiles/allen-andersen", "affiliation": [], "hasCredential": [ { "@type": "EducationalOccupationalCredential", "name": "PhD, Geology, Washington State University" }, { "@type": "EducationalOccupationalCredential", "name": "MSc Geology, Washington State University" }, { "@type": "EducationalOccupationalCredential", "name": "BSc, Geology, Northwest Missouri State University" } ], "knowsAbout": [ { "@type": "Thing", "additionalType": "self-claimed expertise", "name": "Ore Deposits" }, { "@type": "Thing", "additionalType": "self-claimed expertise", "name": "Rare Earth Elements" }, { "@type": "Thing", "additionalType": "self-claimed expertise", "name": "Carbonatites" } ], "memberOf": { "@type": "OrganizationalRole", "name": "staff member", "member": { "@type": "Organization", "name": "U.S. Geological Survey" }, "startDate": "2024-09-21T07:59:07.047501" } }, "ORCID": { "@context": "http://schema.org", "@id": "https://orcid.org/0000-0002-6865-2561", "@reverse": { "creator": [ { "@id": "https://doi.org/10.3133/sir20235012", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.3133/sir20235012" }, "name": "Tungsten resources of the northern Rocky Mountains, Montana and Idaho\u2014 A synthesis and quantitative assessment of skarn-hosted resources" }, { "@id": "https://doi.org/10.5066/p9094rvv", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.5066/p9094rvv" }, "name": "Spatial data associated with tungsten skarn resource assessment of the Northern Rocky Mountains, Montana and Idaho" }, { "@id": "https://doi.org/10.3133/ofr20191023d", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.3133/ofr20191023d" }, "name": "Focus areas for data acquisition for potential domestic resources of 13 critical minerals in the conterminous United States and Puerto Rico \u2014 Antimony, barite, beryllium, chromium, fluorspar, hafnium, helium, magnesium, manganese, potash, uranium, vanadium, and zirconium" }, { "@id": "https://doi.org/10.1130/abs/2022am-381942", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2022am-381942" }, "name": "TIMING OF SILICATE AND CARBONATITE MAGMATISM FORMING THE BEAR LODGE ALKALINE COMPLEX: NEW INSIGHTS FROM 40AR/39AR GEOCHRONOLOGY" }, { "@id": "https://doi.org/10.5066/p94e59kf", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.5066/p94e59kf" }, "name": "Lithogeochemistry and images of selected drill core samples from the Mineral Hill alkaline complex, Wyoming" }, { "@id": "https://doi.org/10.7185/gold2021.8190", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.7185/gold2021.8190" }, "name": "Hydrothermal HFSE(+HREE) mineralization in the Bear Lodge Alkaline Complex\u2014a key to understanding the larger Hicks Dome critical mineral resource?" }, { "@id": "https://doi.org/10.1130/abs/2021cd-363088", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.1130/abs/2021cd-363088" }, "name": "INVESTIGATING THE CRITICAL MINERAL POTENTIAL AND PETROLOGY OF A AU-CU EXPLORATION TARGET, THE MINERAL HILL ALKALINE INTRUSIVE COMPLEX, NORTHEASTERN WYOMING" }, { "@id": "https://doi.org/10.5066/p9rcpamc", "@type": "CreativeWork", "identifier": { "@type": "PropertyValue", "propertyID": "doi", "value": "10.5066/p9rcpamc" }, "name": "Whole-rock geochemical data for the Bear Lodge alkaline complex, Wyoming: 2009 -
