Monazite Dating of Prograde and Retrograde P-T-d paths in the Barrovian terrane of the Thaya window, Bohemian Massif
Original language description
Monazite laser ablation-split-stream inductively coupled plasma-mass spectrometry (LASS) was used to date monazite in situ in micaschists of the Moravian zone in the Thaya window, Bohemian Massif. Petrography and garnet zoning combined with pseudosectionmodelling show that rocks from staurolite-chlorite, staurolite, kyanite and kyanite-sillimanite zones record burial under a moderate geothermal gradient from 4 kbar and similar to 530 degrees C to 5 kbar and 570 degrees C, 6 kbar and 620 degrees C, 8 kbar and 640 degrees C, and 8 kbar and 650 degrees C, respectively. In the kyanite and kyanite-sillimanite zones, garnet rim chemistry and local replacement of garnet by sillimanite-biotite aggregates point to re-equilibration at 6 kbar and 640 degrees C.Monazite abundance increases with metamorphic grade from 5 mu m in the staurolite- zone to > 100 mu m in the kyanite zone. This is interpreted as the onset of prograde monazite growth at staurolite grade, and continued prograde monazite g
