Isotope dating of rocks file profile

24 Apr

Metamorphic zircon in mafic rocks of the Mariánské Lázně Complex, as well as monazite from orthogneiss, and titanite in leucosome yield ages around 380 Ma.On the basis of detailed petrography and cathodoluminescence imaging we conclude that the .380 Ma age reflects the timing of Variscan exhumation and associated decompression melting under upper amphibolite-facies to granulite-facies conditions.
