Lu-Hf ratios of crustal rocks and their bearing on zircon Hf isotope model ages: The effects of accessories
(Elsevier Science, 2018-05)
All other factors being equal, the calculation of zircon Hf two stage model ages (T DM Hf) depends on the particular Lu/Hf value assumed for the magmatic source, the effect being more pronounced as the age difference between ...
