Description
Summary:A reliable direct dating method for archaeometallurgic slag has not yet been achieved. Nevertheless, in archaeological and environmental research information about the age of slag deposits is urgently needed. Metallurgical slag consists of many components. Artificial secondary minerals, for example fayalit, olivine and glass phases are the dominant parts. In many cases primary minerals, called relicts, are also components of slag. Quartz, baryte and fluorite are examples. Such a complex composition leads to large difficulties in paleodose determination if the bulk slag substance is used. On the other hand, slag has a complicated microdosimetry caused by great differences between the individual mineral phases and the possibility of inhomogeneous radionuclide distribution. To overcome these problems in luminescence dating defined phases of the slag have been separated by special chemical and physical procedures. Quartz and glass fractions were investigated by thermoluminescence (TL) and radioluminescence (RL)-spectrometry. Alpha-autoradiography using Kodak LR-115 foil was carried out to get information about the distribution of radionuclides.
