Abstract
In this thesis an specific method for dating local archaeological and geological samples based on the phenomenon of thermoluminescence (TL) using the fine grain and quartz inclusion techniques is developed. Taking into account that this work is interesting for professionals working in the fields of Physics, Chemistry, Archaeology, Anthropology and related sciences, some basic concepts are described to have a better comprehension. Chapter 1 describes the concept of radioactivity, remarking the importance of the different decay types as well as the main radioactive series and the energy liberated in the process. The causes of radioactive desequilibrium are also considered in the case for radon. Another important aspect taken into account in this chapter is the radioisotope production and its relationship with the neutron activation analysis used for the determination of the Uranium and Thorium concentrations in the samples. The TL phenomenon is described in Chapter 2, emphasizing the importance of the process of thermally stimulated luminescence best known as TL and its application for dating minerals of different origin. Chapter 3 shows some important antecedents remarking some aspects of the techniques commonly used for dating purposes. Chapter 4 shows the different methods used for the sample preparation. The techniques used

The techniques used for the {sup 40} K, {sup 238} U and {sup 232} Th determination as well as for the cosmic radiation measurement using locally made TLD are also described. The methods used for the determination of the paleodosis as a function of the TL intensity of each sample are described: special emphasis is taken on the moisture effects as well as in the error limits in the age estimation. Results and conclusions of this study are presented in Chapter 5. These results gave an age of 980 {+-} 90 years for the Edzna ceramic and 1520 {+-} 90 years for the Calixtlahuaca ceramics. The age of the Teotihuacan ceramics was not estimated due to the lack of a stable region of the traps. In the case of paleodunes from the Sonora desert the age estimated was 3810 {+-} 110 years. The results ofthis study are shown as they were obtained from the reader. In conclusion, it can be said, looking at the results of this study, that the TL dating method is a promising method compared with the other techniques traditionally used for dating. This method could be used in the future to date samples from other archaeological sites in which its inhabitants did not leave any ''written''testimony of their presence. On the other hand, the dating of the paleodunes offers the possibility to study the geological phenomena provoked by the climatic changes in the past. The results showed here are the first obtained in Mexico in this field. (Author)}
