DOI: 10.1016/j.chemgeo.2018.01.020
Abstract: Abstract The widespread use of monazite (LREEPO4) in U-Pb geochronology is underpinned by the assumption that it incorporates negligible amounts of Pb during initial growth, and that radiogenic Pb remains immobile after formation. We have… read more here.
