Monazite is a common accessory phosphate mineral that occurs under a wide range of pressure and temperature conditions in sedimentary, metamorphic and igneous rocks.
Ablation conditions during laser ablation inductively-coupled mass spectrometry (LA-ICP-MS) analyses can affect the resulting ages for monazite U-Th/Pb geochronology.
This journal article discusses the analyses from five monazite reference materials for their U-Th/Pb ages using the LA-ICP-MS technique, with a variety of laser spot diameters and repetition rates applied to find the best operational conditions to achieve accurate age data while maintaining maximum precision.
