Petrochronology based on REE-minerals: monazite, allanite, xenotime, apatite

M Engi - Reviews in Mineralogy and Geochemistry, 2017 - pubs.geoscienceworld.org
Monazite, xenotime, and allanite are REE 1-minerals sensu stricto because lanthanides
(La… Lu) and yttrium are critical constituents in them. Apatite does not require REE, but …

Local bulk composition effects on metamorphic mineral assemblages

P Lanari, M Engi - Reviews in Mineralogy and …, 2017 - pubs.geoscienceworld.org
