Abstract: A sequence of interstratified illite-smectite (I-S) and illite in Paleozoic pelites and metapelites from the Iberian Range, Spain, was studied by X-ray diffraction (XRD), scanning electron m...
Replacement of primary monazite by apatite-allanite-epidote coronas in an amphibolite facies granite gneiss from the eastern Alps
Replacement primary monazite apatite-allanite-epidote coronas eastern Alps
2012/3/31
Accessory monazite crystals in granites are commonly unstable during amphibolite fa-cies regional metamorphism and typically become mantled by newly formed apatite-allan-ite-epidote coronas. This dist...
