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.

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 ...
