Zircon in eclogite AV16-47 from Malone Valley. a–e Selected CC images of analysed zircon grains. Scale bar in all images is 30 μm. Measured spots are shown (yellow circles) with the associated date (± 1σ Ma). f REE patterns of zircons. Permian zircon crystals interpreted as magmatic have a steep REE pattern. g Concordia plot of zircon dates and weighted average 206Pb/238U age. The green circle represents the calculated Concordia age
