Toluca-1, a newly recognized enterovirus
Archiv f�r die gesamte Virusforschung, 1973The characteristics of a hemagglutinating enterovirus, Toluca-1, are described. The virus appears to be sufficiently distinct from all previously described enteroviruses to be considered a new serotype.

Tephrochronology of the Toluca Basin, central Mexico
Quaternary Science Reviews, 1999Abstract The major element glass geochemistry of 10 Late Pleistocene and Holocene tephras found in the Toluca Basin in the Trans-Mexican Volcanic Belt is reported for the first time, as a key step towards establishing a tephrochronology for the region.

A geochemical baseline for clays of the Toluca Valley, Mexico
Journal of Archaeological Science: Reports, 2020Abstract This paper presents the results of the INAA of 28 geological clay samples from the Toluca Valley (Upper Lerma) in the State of Mexico, Mexico and the immediately adjacent areas to the north, west, and south. While preliminary, these results demonstrate that there are internal elemental clines within the Toluca Valley, based on elevation (Na,

Abstract The Nevado de Toluca volcano erupted explosively approximately 12.1 ka ago, producing a Plinian–subplinian eruption that deposited the Middle Toluca Pumice (MTP). The MTP consists of white and gray juvenile pumice, gray dense juvenile lapilli, and red altered lithic lapilli. The pumice is dacitic (63.54–65.06 wt.% SiO 2 ) with phenocrysts of

The Lower Toluca Pumice: A ca. 21,700 yr B.P. Plinian eruption of Nevado de Toluca volcano, México
2006Approximately 21,700 yr B.P., after a period of quiescence of ~4800 yr, Nevado de Toluca volcano erupted, producing the Lower Toluca Pumice deposit. The activity generated a 24-km-high Plinian column that lasted ~11–13 h and dispersed 2.3 km (0.8 km dense rock equivalent) of tephra toward the NE, blanketing the Lerma basin, an area occupied today by ...

Lead from troilite of the toluca iron meteorite
Geochimica et Cosmochimica Acta, 1961Lead was recovered from the Toluca meteorite troilite by dithizone extraction and by vaporisation. Lead isotopic ratios were determined mass spectrometrically. With the assumption that the lead originally had the isotopic composition of primeval lead reported by Patterson, a lead-lead age of 4.69 plus or minus 0.12 x 10/sup 9/ years (PbT) or 4.76 plus ...
