Short summary
The (U–Th–Sm) / He dating method helps understand the cooling history of rocks. Synthetic modelling experiments were conducted to explore factors affecting in situ vs. whole-grain (U–Th) / He dates. In situ dates are often 30 % older than whole-grain dates, whereas very rapid cooling makes helium loss negligible, resulting in similar whole-grain and in situ dates. In addition, in situ data can reveal cooling histories even from a single grain by measuring helium distributions.
