Transition from Surface to Shaft mining in Copper and Bronze Age Serbia
Copper isotopes behave differently in near-surface environments than in non-weathering environments found deeper in the earth. By sampling copper isotopes (63 and 65) in metal artifacts from Copper and Bronze Age Serbia, Dr. Mathur and his colleagues discovered the approximate time that people of this region were introduced to shaft mining, a technique already in practice in the middle east.
