Hi Megan

We placed a fair amount of monazite chemistry data in supplementary files to the attached paper.

Best wishes

Subject: searching for monazite chemistry analyses

Dear All,

I am putting together a database of monazite chemistry from the published literature and am looking for datasets with the following essential characteristics:

  1.  Natural metamorphic monazite analyses (EPMA)
  2.  Analyses containing Th, Si and Ca
  3.  Each analysis paired to either a grain temperature (e.g. Y-in-monazite), or a whole rock temperature (conventional thermobarometry or phase diagrams). This can also be a temperature that is extrapolated from other samples in a terrane.
The following additional pieces of information would be useful, but are not essential:

  1.  Pressure conditions (grain or whole rock)
  2.  Whole rock composition for the sample, in particular including P, Ca, Al, Ce, Th, Y
  3.  The microstructural location of the grains.
I would highly appreciate any contributions of datasets that fit the above criteria, or direction to where published versions of the full datasets can be found. I have a particular paucity of data from low temperature (<550 •C) and high temperature (>850 •C).

Many thanks in advance,

Best regards,

Megan Williams
