contents	Preliminary palaeomagnetic stratigraphy of the Tertiary Yemen Volcanics D. H. Tarling J. M. Abou Deeb A. L. Abdeldayem Ciencias de la Tierra Ar Tertiary Ar dating Palaeomagnetism Yemen volcanics Mainly basaltic samples from 60 sites in the Yemen Volcanic Group show somewhat high degrees of between-site directionalscatter, but enable normal, reversed and intermediate polarities to be identified during thermal demagnetisation. Individualchrons cannot be assigned directly from the available stratigraphic controls, but can be estimated using published 39Ar/40Ardeterminations. The Yemen plateau basalts appear to have begun eruption during chron C11r.1r , some 29 Ma ago, and eruptionpersisted for some 3 to 4 Myr, probably terminating during chron C8, some 26 Ma ago. While such an initial assessment needsfurther substantiation, it demonstrates that the combination of radiometric and palaeomagnetic methods provides far greaterreliability than either individual technique alone. 2002 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56841104 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.1 Vol.41
