Monazite, xenotime, and allanite are REE 1-minerals sensu stricto because lanthanides
(La… Lu) and yttrium are critical constituents in them. Apatite does not require REE, but …

Monazite–xenotime thermometry is a potentially powerful technique for understanding the
evolution of Earth systems. While a rich set of experimental and empirical datasets are …

Detrital zircon and igneous zircon U-Pb ages are reported from Proterozoic metamorphic
rocks in northern New Mexico. These data give new insight into the provenance and …

Rare earth element (REE) ore-bearing carbonatite dikes and a stock at Mountain Pass,
California, are spatially associated with a suite of ultrapotassic plutonic rocks, and it has …

Late Mesoproterozoic sedimentary sequences in southwest Laurentia range in age from
1340 to 1035 Ma and record regionally extensive intracratonic sedimentation before and …

Highly variable distributions of yttrium and rare earth elements (Y+ REE s) are documented
in pelitic garnet from the Picuris Mountains, New Mexico, and from Passo del Sole …

Xenotime (YPO4) is iso-structural with zircon-group minerals and lies at one end of a
compositional solid-solution with monazite. As with monazite and zircon, naturally occurring …

It is proposed that the Pinware orogen of eastern Canada, the Baraboo orogen of the
midcontinent, and the Picuris orogen of the southwestern United States delineate a …

U–Pb monazite and zircon geochronology and calculated metamorphic phase diagrams
from drill holes in the northern Gawler Craton, southern Australia, reveal the presence of ca …

The growth of southern Laurentia has been attributed to the accretion of juvenile arc
terranes during the successive 1.74–1.68 Ga Yavapai and 1.65–1.60 Ga Mazatzal …
