Abstract Northwestern South America preserves a record of the assembly of western
Pangaea, its disassembly and initiation of the far western Tethys Wilson Cycle, subsequent …

Apatite is a minor but ubiquitous mineral in most igneous rocks. Although the modal
proportion of apatite in common rocks is generally low, it can reach high concentrations in …

Precise and accurate U–Pb LA–ICPMS dating of many U-bearing accessory minerals (eg
apatite, allanite, titanite and rutile) is often compromised by common Pb. LA–ICPMS dating …

Lusingle bond Hf geochronology is a powerful method to constrain the temporal evolution of
geological systems. Traditional application of this dating method requires time-consuming …

The Moon has had a complex history, with evidence of its primary crust formation obscured
by later impacts. Existing U-Pb dates of> 500 zircons from several locations on the lunar …

The integration of ferroelectric oxide films into microelectronic devices,, combined with the
size reduction constraints imposed by the semiconductor industry, have revived interest in …

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 …

Apatite is a common U‐bearing accessory mineral with a U‐Pb closure temperature of∼
500° C, making U‐Pb dating of apatite a potentially valuable thermochronometer. However …

Apatite is a common U-and Th-bearing accessory mineral in igneous and metamorphic
rocks, and a minor but widespread detrital component in clastic sedimentary rocks. U–Pb …

We report detailed high precision combined single grain U-Pb and Lu-Hf studies of early
zircons to obtain more reliable indications of the extent of mantle depletion and crustal …
