CIFUENTES-NAVA, Gerardo et al. Archaeomagnetic dating of Holocene lava flows from the Ceboruco volcano, western Mexico. Bol. Soc. Geol. Mex [online]. 2019, vol.71, n.2, pp.445-455.  Epub Oct 30, 2019. ISSN 1405-3322.

In this paper we present the magnetic dating results of five independent lava flows belonging to the Ceboruco volcanic field in Jalisco, western Mexico, using the SHADIF14K geomagnetic field prediction model. Five lava flows corresponding to well-documented eruptive events were studied. The ages of these flows have already been established by radiometric methods (C14). In two sites the archaeomagnetic ages coincide with C14 ages previously reported. In one site the archaeomagnetic age is considerably different from the radiocarbon age, possibly due to a discrepancy between one or both of the ages and the actual age of emplacement. For the two remaining lava flows, the paleomagnetic directions were found to be scattered and thus no characteristic remanence was determined. These sites probably underwent some rotation or a later displacement that was unnoticed during the sampling.
