Resistivity measurements made of a Roman homestead to determine the location of a building are discussed in detail. By correlating characteristic maxima of filtered resistivity data, the placement and orientation of walls could be determined. From the measurements, the position and extent of a group of buildings were defined. Prehistoric mining trenches can be located on the basis of anomalously low resistivities. We determined the exact location of a 50 000 year old flint mine on the outskirts of Budapest by geoelectric measurements*and defined the location of the excavation on the basis of geophysical measurements. A three-dimensional picture constructed from apparent resistivities associated with different penetration depths agrees fairly well with the shape of the ancient mine trenches excavated later.

A simple and rapid TL technique was elaborated to date potteries of archaeological origin. Grains from the whole material were used for TL measurements. To assess the beta dose-rate, CaS0

4 : Dy phosphor was mixed with clay powder. A few weeks of exposure was enough to evaluate the beta dose-rate. 15 sherd fragments were studied and for most of them the obtained TL age was found to be within 20 per cent of the archaeological age.

(In Hungarian) Fragments of ancient smelting hearth from the site Kányaszurdok were dated by thermoluminescence, XRF, alpha-counting and TL dosimetry were used for dose-rate determinations. The obtained ages are 1190 and 1263 years BP, with a realistic estimate of +20... —10% overall uncertainty, mostly due to incomplete informations about burial conditions. Benkő L.: Thermoluminescence dating of dental enamel = Nuclear Instruments and Methods 175 pp. 227-229, 1980. The thermoluminescent response of the synthetic material hydroxylapatite was studied, this material being the fundamental inorganic constituent of dental enamel. In order to make an attempt at archaeological TL dating of teeth, a chemical deproteination procedure of enamel was established, and the pre-dose effects of separated mineral grains extracted from 100 to 6000 years old human teeth were investigated. From ten samples, six turned out to have qualitatively reasonable pre-dose characterictics. Benkő L. — Koszorús L.: Application of pre-dose dating to dental enamel = Revue d'Archéométrie, 1980, No. 4, pp. 149-152. Preliminary TL measurements were carried out on hydroxylapatite, the chief mineral constituent of bone and teeth. Besides an intense 60°C peak in hydroxylapatite, additio-
