206Pb/ 238U error is the quadratic additions of the within run precision (2 SE) and the external reproducibility (2 SD) of the
reference zircon. 207Pb/206Pb error propagation (207Pb signal dependent) following Gerdes & Zeh (2009). 207Pb/235U error is the
quadratic addition of the 207Pb/206Pb and 206Pb/238U uncertainty.
a Within run background-corrected mean 207Pb signal in cps (counts per second).
b U and Pb content and Th/U ratio were calculated relative to GJ-1 reference zircon.
c Percentage of the common Pb on the 206Pb. b.d. = below detection limit.
d Pb/U and Pb/Pb ratios. Corrected for background, within-run Pb/U fractionation (in case of 206Pb/238U) and common Pb using
Stacy and Kramers (1975) model Pb composition and subsequently normalised to GJ-1 (ID-TIMS value/measured value);
207Pb/ 235U calculated using (( 207Pb/206Pb)*(238U/206Pb)*137.88).
e ZŚŽ ;ʌͿ ŝƐ ƚŚĞ ;206Pb/238U)/(207Pb/235U) error correlation coefficient.
f Pb/U and Pb/Pb ages.
g Degree of concordance = (( 206Pb/238U age)/(207Pb/206Pb age)) x 100.
h Mean of 13 (91500), 13 (Felix), 13 (Plesovice), and 26(GJ-1) analyses, respectively.
