Sericite–chlorite phyllite from the Bôrka Nappe (locality Honce village, sample OS-07-128): a photomicrograph of the sericite–chlorite phyllite, crossed pol.; b photomicrograph of pseudomorphs after glaucophane, parallel pol.; c post-tectonic idiomorphic porphyroblast of monazite, crossed pol.; d X-ray compositional maps of Th distribution in idiomorphic monazite porphyroblast (for chemical analyses see Online resources 7 and 8); e and f sericite–chlorite phyllite from the Bôrka Nappe (locality Honce, sample OS-07-117): X-ray compositional maps, distribution of K (e) and Na (f) shows relics of the older paragonite grains in younger muscovite/phengite. Increase in the K and Na contents is indicated by blue-green-yellow–red colours (for chemical analyses see Online resource 1)
