Trace element composition of zircons (chondrite-noramlized after Sun and McDonough, 1989). Dashed gray lines represent the upper and lower bounds of the data from sample B19-1417 and are shown for comparison. The solid gray lines and areas represent the change from a magmatic to a hydrothermal REE pattern after Pettke et al. (2005). Note that the left and right fields each belong to the same sample. a RG1 (sample B19-1417), b RG2 (sample B20-3247), c QB-SZ (sample B20-2801)
