Regolith-hosted rare earth element (REE) deposits, also called ion-adsorption or weathered
crust elution-deposited REE deposits are distributed over Jiangxi, Guangdong, Fujian …

The AXO4 monazite-type compounds form an extended family that is described in this
review in terms of field of stability versus composition. All the substitution possibilities on the …

Accurate thermochronologic interpretation of zircon (U-Th)/He dates requires a realistic and
practically useful understanding of He diffusion kinetics in natural zircon, ideally across the …

This article presents a current (as of September 2019) list of recommended ages for proven
terrestrial impact structures (n= 200) and deposits (n= 46) sourced from the primary …

Diffusion of Pb was characterized in natural and synthetic zircon under a range of
conditions. In most experiments, mixtures of Pb sulfate and ground zircon were used as the …

Despite its low abundance in most rocks, zircon is extraordinarily useful in interpreting
crustal histories. The importance of U-Th-Pb isotopic dating of zircon is well and long …

We report measurements of Pb diffusion in both synthetic (CePO4) and natural monazites
run under dry, 1-atm conditions. Powdered mixtures of prereacted CePO4 and PbZrO3 were …

Annealing of the radiation damage generated in α-decay events is a common phenomenon
in natural zircons. We have studied relationships between radiation damage, age and …

The disposition of actinides, most recently 239Pu from dismantled nuclear weapons,
requires effective containment of waste generated by the nuclear fuel cycle. Because …

Ion adsorption-type rare earth element (REE) deposits are the predominant source of heavy
REE (HREEs) and yttrium in the world. Economic examples of the deposits are confined …
