FIELDS OF RESEARCHUMR 5138, "Archeometry and archaeology", brings together pre-history specialists, archaeologists for the Gallo-Roman and medieval periods, sediment and petrography geologists, physicists and chemists specialised in the analysis of materials and carbon 14 dating.The work of the UMR relies on analytical equipment from the Ceramology laboratory and the Carbon dating centre and on the competences of its archaeology teams.
The various UMR are involved in a large number of countries: Algeria, Bulgaria, Egypt, Greece, Italy, Lebanon, Libya, Poland, Portugal, Syria, Tunisia, Turkey, Ukraine., and with its physical nature by petrology and metallurgy, turns to the remaining information he can get from his colleagues in the natural sciences.UMR 5138 (mixed research unit) was set up in 2001 and is called "Archeometry and archaeology: origin, dating and materials technologies".The ruined castle, located in eastern Slovakia, sat on a hill overlooking the trade route to Poland.“When we started our research six years ago, we had no gateway, now we have two of them,” said researcher Jaroslav Gorás.The other part is the interpretation in cultural and historical contexts of the facts established—by chance, by fieldwork, and by digging—about the material remains of man’s past.
This task of interpretation has five main aspects., the first requirement is a good and objective taxonomy.
It was 1984 and the Edgar Cayce Foundation, named for an early twentieth-century psychic who claimed that the Sphinx and Khufu's Great Pyramid were built in 10,500 B. Old friends and supporters of the deceased psychic had visited Giza in the early 1980s and several of them were willing to put their beliefs to the test by radiocarbon dating the Great Pyramid. and built the Giza Pyramids in a span of 85 years between 25 B. In spite of this discrepancy, the radiocarbon dates confirmed that the Great Pyramid belonged to the historical era studied by Egyptologists.
Archaeologists believe it is the work of the Old Kingdom Dynasty 4 society that rose to prominence in the Nile Valley from ca. In dealing with the 374-year discrepancy, we had to consider the old wood problem.
In 1984 we thought it was unlikely that the pyramid builders consistently used centuries-old Egyptian wood as fuel in preparing mortar.
Ancient Egypt's population was compressed in the narrow confines of the Nile Valley with a tree cover, we assumed, that was sparse compared to less arid lands.
A man called Willard F Libby pioneered it at the University of Chicago in the 50's. This is now the most widely used method of age estimation in the field of archaeology.
