Monazite is a light rare earth element (LREE)-bearing phosphate mineral that is present in a
wide variety of rock types, has an extremely variable composition reflecting host rock …

The present-day 238U/235U ratio has fundamental implications for uranium-lead
geochronology and cosmochronology. A value of 137.88 has previously been considered …

Elemental fractionation effects during analysis are the most significant impediment to
obtaining precise and accurate U‐Pb ages by laser ablation ICPMS. Several methods have …

Detrital zircon geochronology is rapidly evolving into a very powerful tool for determining the
provenance and maximum depositional age of clastic strata. This rapid evolution is being …

Matrix-matched calibration by natural zircon standards and analysis of natural materials as a
reference are the principle methods for achieving accurate results in microbeam U–Pb …

Laser-ablation split-stream (LASS) analysis—high-speed, high spatial-resolution,
simultaneous isotopic and elemental analysis—enables petrochronology at a new level …

U‐Th‐Pb geochronology by laser ablation–multicollector–inductively coupled plasma–mass
