About research methods of the artifacts of El Toro
It is known that the artifacts of El Toro were found in graves without archaeological support and stratigraphic analysis. This fact significantly complicates objective study and dating.
Given this important fact, it is necessary and possible to use complex research methods in the study of the artifacts of El Toro, including:
- Radiocarbon dating of organic residues;
- Thermoluminescent dating of the ceramics;
- Chemical analysis of composition of organics, ceramics and metals;
- Microanalysis of patina and traces of the processing of the stone;
- Gathering and analysis of evidence about the findings of the artifacts;
- Comparative analysis of the artifacts.
None of these methods is “absolute” proof, but in combination, complementing each other, in our opinion, they can help to get closer to unraveling the mysteries of the unusual artifacts.
- Radiocarbon dating
As it was previously reported, in 2012, radiocarbon dating of the two artifacts of El Toro was conducted with the assistance of the Austrian researcher Klaus Dona. The objects of the test were samples of organic adhesive, which connected stone fragments of the artifact.
Given that the percentage of artifacts of El Toro with the use of glue in total number of artefacts is about 10-15%, conducting of the radiocarbon dating is reasonable and promising.
One of the areas of use of carbon-test to analyze artifacts of El Toro is also the dating of organic remnants that could be preserved in the artifacts, for example in the smoking pipes. From private sources (the message of Brett Girloy) we know about conducting of carbon test on the remains of tobacco, preserved inside one of the stone pipes that were found on the territory of El Toro. The age of this organic matter was estimated at 5 thousand years.
We should generally note that despite the shortcomings and criticism of the method of radiocarbon dating (04), it has generally proved its effectiveness as the leading physic-chemical method for direct dating of organic matter in archaeology. Radiocarbon dating has been successfully applied in practice research for many years, constantly improving both technically and methodically.
- Thermoluminescent dating of the ceramics.
Presence of the ceramics in the composition of the artifacts of El Toro allows the usage of this important method for direct dating of archaeological objects. As it is known, this method uses the measurement of the energy emitted by a mineral sample as the result of heating. In the case of the ceramics the results of the TL-test allows to obtain the approximate date of its manufacturing by a method of firing (at temperatures below 550-600ºC). Wide application of TL method in the practice of dating of the ancient objects helped to identify its certain weaknesses and limitations (the problem of calibration, possibility of falsification of the result, relatively large error, geological limitations of dating for some regions). But in the case of El Toro artifacts, application of the TL method is very important, as it allows establishing or disproving the fact that these objects are ancient.
- Chemical analysis of the materials.
The study of the chemical composition does not allow to directly determine the age of an artifact, but nevertheless it gives important characteristics for the indirect assessment. For example, in 2013 chemical analysis of two ceramic artifacts El Toro was conducted in Mexico, which revealed a number of features of the composition of the ceramics, indicating their ancient age. Determination of the composition of the adhesive by the method of infrared spectrography and spectral analysis of precious metals is very promising for the artifacts of El Toro.
4. Microanalysis of traces of patina and processing of the artifacts of El Toro with the help of a microscope allows in many cases to reliably detect the modern fakes of the artifacts (artificial patina, traces of mechanical or laser processing, etc.). Dr. Garcia Sanchez, who founded a Mexican public organization Nahui Ollin, repeatedly informed about such results of the analysis of the artifacts of El Toro.
We believe that the results of various analyses of the artifacts of El Toro ultimately should lead to a comprehensive professional archaeological research of the unique complex of El Toro hills.
