Gallet et al. Here, we report new PI data, in an effort to reduce the uncertainty of this result and applying updated methods. Cleveland Scene Bolivar Rd. Be spontaneous and original. We interpret this to be the case for the Ceboruco lava flow, while three of the six sites of the lava flow may have been partly or completely affected by movements after thermoremanent magnetization acquisition. Each flow was sampled in at least four sites, in order to unravel between site variations. Tables 1 and 2 list these data for the lava and Ceboruco flow sites, respectively. Nonetheless, the different model predictions available show, for some intervals, significant differences. These very recent eruptions with a total volume of about 4 km 3 , occurring after AD, are difficult to date by the radiocarbon method, mainly because of the short between eruption intervals not permitting any soil formation. Two lava flows from the Ceboruco volcano in west-central Mexico were sampled for palaeomagnetic dating.

Quatern Int 43—— Each standard paleomagnetic core was cut into eight specimens, which were pressed into standard-dimension cylindrical salt pellets and labeled from 1 to 8 e. As listed in Tables 1 and 2overall mean directions are available as based on individual specimens as well as based on four site-mean directions. The paleomagnetic sampling of lava flows was done previously and results were reported by Cervantes-Solano et al. Please note: Oxford University Press is not responsible for the content or functionality of any supporting materials supplied by the authors. Most of the specimens showed only minor secondary magnetization components of probably viscous origin, which were removed in AF amplitudes of 20 mT or less Figs 6a and b.

1 INTRODUCTION

Heating and cooling curves are indicated by arrows and red and blue colours, respectively. Therefore, the dispersion probably reflects post-cooling movement of the rocks, although this was not detected in the field. The combined probability density derived from these data is shown at the bottom. Newest Slideshows. This enabled us to analyze sister samples, minimizing the possibility of within-flow heterogeneities, as well as the application of a multi-methodological exercise on almost the same material. Palaeomagnetic dating of a the lava flow and b the Ceboruco lava flow. This result is acceptable and the coincidence with the TTC result suggests that these PI data are reliable. E Madrid, Spain. In this work, we use the lava to see how works the palaeomagnetic dating method in this region and then apply it to the Ceboruco flow with unknown age. Local journalism is information.

A mean multi-method PI flow value of Also indicated are overall flow-mean directions calculated from all ChRM directions, as well as calculated from the site-mean directions.

The layout of the website has an old-school essence to it but it is incredibly easy to navigate. It is a monogenetic cone whose lavas overlay an area of approximately 80 km 2 in which seven flow-units are identified Fig. Jackson A. Additionally, concave-up shape Arai plots are rejected for the PI calculations because, in such cases, the remanence is very likely carried by MD grains Levi Profile photos are important: With so many members on these sites, it is better to stand out visually.

Palaeomagnetic dating is based on the comparison of the geomagnetic field recorded in suitable material of unknown age with a set of reference data of known age, established for the same geographical region, which are used to constrain the classical palaeosecular variation PSV master curves. Phil Trans R Soc A — Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. This means that all post-plinian lava flows had already been emplaced by the arrival of the Spanish conquerors in We would like to note that the obtained declination is indistinguishable within the uncertainty from the magnetic declination of 9. Chadima, M. Unfortunately, no better sites were found for this flow. All these observations strongly suggest sampling multiple sites to be able to recognize unreliable results and finally to recover a reliable flow-mean direction which then may be used for an accurate palaeomagnetic dating.
