Who reported the first Earth Science material compositions by EPMA?
Anything older than this one?
STUMPFL, E.F. (1961). Some new platinum-rich minerals identified with the electron microanalyser. Mineralog Mag 32, 833–847
Many thanks

Looking at the Stumpfl article, it references Castaing's 1960 chapter Electron Probe Microanalysis in Advances in Electronics and Electron Physics (https://doi.org/10.1016/S0065-2539(08)60212-7). In that, there's a section on mineralogy that references some early work on earth science topics:
Guillemin, C. and Capitant, M., (1960) Utilisation de la microsonde électronique de Castaing pour des études minéralogiques, a report from the 21st international geological congress
Castaing, R., and Fredriksson, K., Analyses of cosmic spherules with an X-ray microanalyser Geochim. et Cosmhim. Acta 14, 114 (1958).
https://doi.org/10.1016/0016-7037(58)90099-1
Plus a couple from 1957 that I couldn't access.
A useful source of some of the early literature is:

See "Microprobe Analysis, 3. Applications".
Birks & Brooks (1957) mention analysis of a copper-iron mineral and its inclusions, which is subsequently elaborated upon in Birks et al. (1959):
