Urrutia-Fucugauchi Ciencias de la Tierra Paleomagnetism paleointensity microwave technique We report a microwave paleointensity study of historic lavas from Paricutin volcano, erupted during the period between1943 and 1948. Most samples are characterized by uni-vectorial orthogonal plots. Rock-magnetic and microscopy studiesindicate pseudo-single-domain titanomagnetites as the remanence carriers. The microwave paleointensity technique was appliedto selected samples using both Kono and Ueno (1977) and Coe et al. (1978) variants of the Thellier method. The samplesyielded technically high quality paleointensity results, though show high within-flow dispersion and are significantly differentfrom the expected value of 45mT. This is also seen in results using the Thellier method (Urrutia-Fucugauchi et al., 2004).Explanations for this behaviour are explored, with reference to other historic lava studies. The technically high quality of theresults suggest there is no criteria that can distinguish between correct and erroneous paleointensity data. 2005 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56844302 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.44 |
