LEAD ISOTOPE ANALYSIS BY MASS SPECTROMETRY AND ITS APPLICATION IN ARCHAEOMETRY

Source identification efforts by scientists to establish a boundary for a particular ore deposite used in the production of Bronze ABe copper artifacts have larsely failed for various mineralogical and metallurgical reasons. The isotopic composition of lead, an element presents in a minor amount in many copper ores and ts, is unchanged through physical and chemical processes and can be used to determine the sources of the copper used in copper and copper based bronze objects. Results show that for upper Euphrates, located in the eastern part of Turkey, Maden and Keban copper ores may have been an hnportant copper sources.
