Abstract:Se presentan resultados preliminares de un estudio conjunto de paleomagnetismo, reconocimiento geológico de campo y de-fechamiento de K-Ar encaminado a documentar la estratigrafía volcánica en las zonas geotérmicas de Ixtlan de los Hervores-Los Negritos, Estado de Michoacán. Se determinaron polaridades, direcciones de magnetización remanente y polos geomagneticos virtuales para catorce sitios y se contó con cinco fechamientos de K-Ar de unidades volc3nicas seleccionadas en las zonas geotérmicas de Ixtlan de lo… Show more
Miocene. These new palaeomagnetic data support the idea that the eastern TMVB since the late Miocene, has been a zone of extension with a little, left-lateral shear component.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
