>I work on lawsonite and pseudomorphs after lawsonite to constrain the
metamorphic evolution of the Maksyutov complex, S-Ural, Russia. Thereby
coworkers found a lot of Sr in pseudomorphs after lawsonite. I know from
literature,that Sr may be incorporated into fresh lawsonite, it exists even
a Sr-analogue of lawsonite and sector zoning of Sr in lawsonite is described
too. Now I liked to do the test: Do I still recognize a relic Sr sector
zoning in the pseudormorphs after lawsonite? In Darmstadt we have technical
facilities to detect trace element by microprobe techniques, but this is a
new method for me. Is anybody there, who has experience in trace element
analysis by microprobe in general or Sr in particular?

Hello Bernhard,
Perhaps the latest word on the subject of trace-element analysis
with the electron microprobe is:
Michel Fialin et al, 1999, Trace-element analysis with the electron
microprobe: New data and perspectives: American Mineralogist, v. 84, pp. 70
- 77.
Good luck!
Tomas Feininger
Geologist
