Apatite recrystallisation during prograde metamorphism, Cooma, southeast Australia: implications for using an apatite-graphite association as a biotracer in ancient metasedimentary rocks
Early Silurian low-pressure (<500 MPa) greenschist to granulite facies metamorphism in Ordovician sedimentary rocks of the Cooma Complex culminating in the production of the Cooma Granodiorite, Lachlan Fold Belt (southeast Australia) provides an opportunity to determine the physical and chemical response of apatite (Ca phosphate) to prograde metamorphism. Electron probe elemental mapping (P, Ca, Ce, Si) of metapelite polished sections shows that apatite grains become less abundant but larger...[Show more]
