  1. Sample locations: BS 3, BS 21a: road cuts near Garić-grad ruin; BS 36G: Jelen grad ruin; BS 2: Pleterac quarry; BS 26: 3.5 km W of Šimljanik
  2. aWithin run background-corrected mean 207Pb signal
  3. bU and Pb content and Th/U ratio were calculated relative to GJ-1 reference zircon
  4. cCorrected for background and within-run Pb/U fractionation (in case of 206Pb/238U) and common Pb using Stacey 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*1/137.88)
  5. dRho is the error correlation defined as err206Pb/238U/err207Pb/235U
  6. eDegree of concordance = 238U/206Pb/207Pb/206Pb *100
