摘要:

ABSTRACTSThe inorganic inclusions contained in amber fragments from Baltic regions and from the Simeto basin (Sicily, Italy) have been analyzed. The study, performed with the aid of a scanning electron microscope, shows specimen similarities and differences that are dependent on the place of origin.

摘要:

ABSTRACTSWith the aim of establishing the provenance of pumices along the North Coast of Cyprus, from Morphou to Kormakiti, chemical analysis, refractive indices determinations and mineralogical examination have been performed.On the basis of the experimental data the pumices can be distinguished into two groups. For the first one a provenance from Santorini can be established, for the second Yali, Kos and Milos can be taken into consideration as source localities.

摘要:

ABSTRACTSA method is described for obtaining accurate thin slices for thermoluminescence measurement of uniform materials, in particular burnt flint, which does not subject these materials to heat during the cutting process. Cutting is by means of a fine wire impregnated with diamond grit and gives a high standard of surface finish such that very little further preparation is needed. Thus, by the use of this method, there is a considerable saving in time as well as minimal risk of damage to the TL record of the materials during sampling.

摘要:

ABSTRACTSEight sherds from Hemamieh and two from Qurna‐Tarif, both Predynastic settlement sites in the Nile valley, have been dated by the thermoluminescence method (quartz inclusion technique). The results put the Badarian phase at Hemamieh in the sixth and fifth milleniumb.c., and the Gerzean phase in the first half of the fourth milleniumb.c.The dates for the village of Qurna‐Tarif fall around 4000

摘要:

ABSTRACTSSupralinearity correction in the routine ‘fine‐grain’ technique of thermoluminescence dating of pottery has previously been regarded as empirical, but can now be shown to depend in many cases upon the previous radiation history of the material. The likely impact of this effect upon ceramic and bronze dating is considered and illust

摘要:

ABSTRACTSRecent studies on pottery and related materials have shown there to be cases where the degree of supralinearity is dependent on the previous radiation history of the sample. Results are presented of two investigations of this variation with pre‐dose: one using pottery, the other using fired feldspars. For these samples no simple form for the variation can be inferre

摘要:

ABSTRACTSA new system for specifying alpha source strength, in terms of track length per unit volume of sample, is proposed. It is based on the experimental observation that the TL induced per unit length of track is essentially independent of alpha particle energy. The new system avoids the need to make assumptions about sampple stopping power and it is shown to be consonant with the old system as long as up‐to‐date evaluation of alpha ranges is used. A revised table of dose‐rate data is
