U-Pb Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) isotopic data were collected for igneous and hydrothermal monazite from a carbonatite dike and hydrothermally altered pegmatite dike, respectively, to determine the age of carbonatite emplacement and rare earth element (REE) mineralization in the Wet Mountains, Colorado. Fifty analyses from three monazite grains from each sample yielded reliable 206Pb/238U data. Sample locations were recording using a handheld Global Positioning System.
