摘要:

本文通过张掖西城驿遗址文化层沉积物及现代表土沉积物元素地球化学分析,结合高分辨率碳化植物种子14C 测年和最新考古发掘资料,揭示了西城驿遗址4200-3500 BP cal期间人类活动特征,佐证了不同文化阶段人类冶金活动强度变化。Rb/Sr比值、磁化率和重金属元素(Cu、Zn、Pb、As、Ni)含量变化过程显示,西城驿地区4200-4000 BP cal马厂文化时期人类活动增强,冶金活动开始出现;4000-3700 BP cal西城驿文化时期出现了冶金高峰期;四坝文化时期(3700-3500 BP cal)冶金活动强度相对减弱。

关键词: 西城驿遗址, 元素地球化学, 人类活动强度, 铜冶炼

Abstract:

This paper describes elemental geochemical analysis of natural and anthropogenic sediment samples systematically collected from the Xichengyi late Neolithic-Bronze Age site at Zhangye, and combined high-resolution radiocarbon (14C) dates of charred plants seeds with the latest archaeological findings. Results indicated characteristic human activities between 4200 and 3500 BP cal including changes in the intensity of human smelting activities during different prehistoric phases. Variations in Rb/Sr, magnetic susceptibility and heavy metals (Cu, Zn, Pb, As and Ni) suggested that with an increase in human activities, copper smelting began to appear from 4200 to 4000 BP cal. Copper smelting substantially increased between 4000 and 3700 BP cal and declined after 3700 BP cal.

Key words: Xichengyi site, Elemental geochemistry, Human activity, Copper smelting
