The chemical composition of allanite-(La) has been determined by electron-microprobe...692(60)(013), 2.611(50)( 3̄11), and 2.174(25)( 4̄01). Allanite-(La) is monoclinic, P21/m, with a 8.914(4), b 5 |  | | Report (volume) | | geochemical important accessory minerals such as allanite, and minerals typical for rare bulk compositions...magmatic regime (Chapter 9, Schmidt and Poli).
