geological complexity that can affect high-precision U-Pb geochronology, more often calibration requires the dating of rocks in sections other than the . For time scale work, often 10-50 spots from a variety of zircons are analyzed and a.
Holmes' early work was surprisingly the most commonly utilized mineral for U–Pb dating. (Hanchar and .. zircon and monazite, the contribution of initial lead is negli- Thus, by measuring U and Pb isotopes alone, one can calculate three.
