Abstract
The archaeological materials which were dated in the Heidelberg TL-laboratory include bricks and burnt clay from a Roman villa, burnt clay from an ancient lime furnace, and <i>Bandkeramik</i> sherds from the Aldenhovener Platte. For most samples, both the fine-grain and the quartz inclusion techniques were used in TL dating. The annual dose rates were determined by chemical analysis on the ceramic samples and the surrounding soils. Potassium was measured by atomic absorption. The uranium and thorium contributions were determined by a Ã8-counting and by fission track techniques. The dose-rates were corrected for the natural water contents in sherds and soil. From a Roman villa in Bad Kreuznach, a ceramic pipe, bricks and clay-lining of a stove were dated. The fine-grain and quartz inclusion ages agree well with the independently known archaeological ages 2nd and 3rd century AD. The dating also was applied to an ancient lime furnace near Fribourg, Switzerland, in order to distinguish between the possible Roman or Medieval ages. From the furnace wall, consisting of rock boulders imbedded in clay, burnt clay samples were taken. Their fine-grain dating (2060 ± 220 years) revealed a Roman age for the lime furnace, which is supported by archaeomagnetic dating carried out by Dr. J. Wagner in Geneva. For the sherds from the <i>Mettlere Bandkeramik</i> the fine-grain ages agree very well with the quartz inclusion ages. On the average an age of 4590BC ± 490 a (1sigma) was found. With regard to the dispute short (2700-2900BC) versus long (3900-4500BC) chronologies for the Bandkeramik period in Middle Europe, the TL age supports clearly the latter one. The high TL age also indicates that the dendrochronological corrections of conventional <sup>14</sup>C ages are valid for the Middle European Bandkeramik period. Further research is needed regarding this problem. -- AATA
