SHRIMP U-Pb xenotime geochronology and its application to dating mineralisation, sediment deposition and metamorphism

Cross, Andrew Joseph


Diagenetic and hydrothermal xenotime typically occurs in rocks as tiny crystals (≤20 μm), either individually or as outgrowths on a zircon substrate. Currently only large radius ion microprobes such as the SHRIMP or Cameca 1270/1280 have the high sensitivity and spatial resolution necessary to analyse these crystals for U-Th-Pb isotopes. However, such analyses are prone to significant matrix effects (ME) related to the large natural range of U (0 to ~9 wt%) and REE (ΣREE: -12 to 22...[Show more]
