ABSTRACT
The purpose of this research is the dating of some mammoth bones from the Valley of Mexico, with the uranium-series method, which can determine the activity of the isotopic relationships 234U/238U and 230 Th/234U. Since not all samples could be dated by this method, it was necessary to apply other techniques as well. First of all, the total concentration of uranium was determined in mammoth bones by U. V. spectrometry, then a study of the conservation state of mammoth bone was carried out by scanning electron microscopy and X-ray diffraction. In this way the limiting factors at the application of this method for dating mammoth bones can be determined.
