Pb* indicates the radiogenic portions, respectively.									
Data were 204Pb corrected, using measured values.												
% discord. = % discordance defined as [(206Pb/238age)/(207Pb/206b)]×100; 
§ ages with the discordant greater than 5% are also show in table 2 and CL images, but not discussed in text.	
Errors are 1-sigma
