The inhomogeneous geographical distribution and existing time gaps (especially between the VI and IX century) in the Spanish archaeomagnetic database are the principal problems that need to be solved. On the one hand, Spain has a very rich archaeological heritage and, as result of economic development, a wide variety of remains is continually discovered. Unfortunately, in many cases newly discovered sites need to be destroyed as part of this development and our activity is especially oriented to reduce this loss of information. Within this framework, new
contacts with Iberian archaeologists have been
established, and about 15 new sites have been
sampled. This number will continue to increase as new
sites are identified and sampled. In addition to
refining and enlarging the Iberian secular variation curve, some
of the new sites are of interest in testing the precision
of the archaeomagnetic method.
A detailed investigation of the
magnetic properties of the sampled material is carried out.
Blocking temperature and coercivity spectra of both,
the natural and laboratory-imparted remanences
are used to define the mineral phases carrying the remanent
magnetisation and to choose the best demagnetisation technique.
These experiments are complemented by magnetic hysteresis
measurements. Further information will be provided by
detailed thin section, electron microscopy and
other compositional analyses such as X-Ray diffraction.
Andrzej Rakowski The aim of my study is "Anthropogenic changes of radiocarbon concentration in modern wood". I am a specialist in radiocarbon dating, and I hope my knowledge in this matter can help solving problems concerning the chronology of archaeological sites which were or will be examined. Using atomic mass spectroscopy (AMS for short), extremely small carbon samples (containing < 1mg of organic Carbon) are necessary for dating only. It can be useful for dating for example soot from the furnace or microfossils deposited in lake sediments in order to build a precise chronology for the site. |
