摘要: A 268 cm section of sediment core from Liangzhi Lake in Hubei province central China was used to assess the use and accumulation metals lake past 7,000 years. The concentrations trace metals, including Cu, Pb, Ni, Zn, major elements, Ca, Fe, Mg, a 14C- dated segment were analyzed. Historical trends on input around 5000 BC present recorded sediments, representing about years history mining utilization China. Zn increased gradually 3000 ± 328 BC, indicating start Bronze Age ancient During period 467 257 215 221 AD, there rapid increase these enormous inputs at that time. This era corresponded China’s Warring States Period (475− BC) early Han Dynasty (206 BC−220 AD), during which copp...
