Revisiting lead isotope data in Shang and Western Zhou ...

Archaeological lead isotope interpretation is, hence, usually based on comparison between ore and object data in conventional bi-plots. Our previous analysis of lead isotope data from Shang and Zhou bronzes use a different approach, namely plotting 1/Pb concentration against 206 Pb/ 204 Pb ratio (Pollard & Bray Reference Pollard and Bray 2015).

Out of Oblivion: A landscape through time

Lead ore is not continuous in the vein, but often found in pockets, which is one reason why lead mining could be a very speculative activity. Mining from an early date relied on shafts. The course of out-cropping veins is often marked by lines of closely spaced mounds, which in the past have been incorrectly called bell pits.
