Published Papers


Key phases: monazite, xenotime, apatite, allanite, titanite

Goals

  1. obtain accurate/precise ages for (U, Th)-bearing accessories
  2. determine reactions/events responsible for accessory-phase growth
  3. estimate first-pass thermodynamic properties for accessories (G, H, S, Cp)
  4. use ages, reactions, differential thermodynamic models to constrain P-T-t paths

Rollover shows monazite with

1: 4 distinct yttrium zones

2: estimated growth temp of each zone (mouse over)

3: assemblage/zone at growth time of each zone (mouse down)
