Abstract

Copper artefacts from the Palestinian EB I/ II Kfar Monash hoard are made of two distinct types of metal. Adzes, a spearhead and a long, curved knife consist of arsenic-and nickel-rich copper, with arsenic contents between 0.4% and 3.88% and an average As/ Ni ratio of 1.4. All other implements, weapons and also the enigmatic thin metal sheets (mean thickness about half a millimeter) are very pure copper. The same grouping is also observed in the lead isotopy of the objects : 206Pb-normalized abundance ratios of the AsNi-rich copper form a tight cluster at 208Pb/ 206Pb≈ 2.061, 207Pb/ 206Pb≈ 0.829 and 204Pb/ 206Pb≈ 0.0528 ; objects made of pure copper show a wide variation in abundance ratios which are much higher ; 208Pb/ 206Pb, e. g., varie...
