A series of laboratory annealing experiments on zircon fission tracks has been carried out under heating conditions of 350–750°C for 10−1–103 hr (i.e. 4.5 min-∼40 days). Variation in the confined lengths of spontaneous ...

Increasing temperature causes fading of fission tracks (FTs) in minerals, which has been quantified by many laboratory heating experiments in atmosphere. In order to elucidate whether or not FT annealing at hydrothermally ...

We performed a systematic study of (U-Th)/He ages of volcanic zircons of known eruption age to establish a reliable protocol for zircon He dating and to validate the resulting ages. Using laser He extraction and dissolution ...
