[1] Pan et al. [2002] experimentally investigated the validity of the Shaw paleointensity method [Shaw, 1974; Kono, 1978; Rolph and Shaw, 1985] using laboratoryinduced thermal remanent magnetization (TRM) to simulate natural remanent magnetization (NRM). They prepared fully demagnetized Cretaceous basalt samples by exposing them to a 150-mT alternating field (AF), and then heating them in an ov...
