摘要:
金属的使用与冶炼是人类社会发展过程中-项革命性事件。河西走廊地区全新世条湖湖相沉积元素地球化学记录显示,10500-9500cal aBP和8000-7200cal aBP时段Cu、Pb、Zn、Ni元素含量高值区,分别对应了早全新世增温期冰川融水量增加和全新世适宜期季风降水的增强。Cu、As、Pb、Zn、Ni含量在4200-3700cal aBP时段出现最高峰值,另外Cu、Pb、Zn、Ni4种元素在3000-2700和2100-1900cal aBP时段出现较高峰值。4200-3700cal aBP时段元素异常记录了我国西北地区最早的青铜冶炼,As元素是这-时期青铜合金的主要成份。另外,西周时期(3000-2700cal aBP)和汉代(2100-1900cal aBP)Cu、Pb、Zn、Ni元素峰值,可能是先民青铜冶炼的结果。元素地球化学记录不仅可以判定早期青铜冶炼的起迄时间,也提供了甄别不同时代青铜合金元素组成变化的信息。

Abstract:
The utilization and smelting of metal is a revolutionary event during developing process of human society. The records ofelement geochemistry from lacustrine sediment at Lake Tiaohu in Hexi Corridor, during Holocene indicated that the high values ofelement such as Cu, Pb, Zn, and Ni appeared in the period of 10500-9500 and 8000-7200ca1 aBP, responding to the episodeof acial meltwater rising in the period of increasing temperature in early Holocene of the and the period of precipitation strengthduring Holocene optimum, respectively. The highest peak values of Cu, As, Pb, Zn and Ni appeared between 4200 and 3700ca1aBP. Additionally, the secondary high values of Cu, Pb, Zn and Ni appeared in the period of 3001-2700ca1 aBP and 2100-1900ca1 aBP. The element abnormality between 4200 and 3700ca1 aBP record the earliest bronze smelting in Northwest China andthe element of arsenic was the major component in bronze alloy in this period. The element high values of Cu, Pb, Zn, Ni in West-ern Zhou Dynasty (3000-2700ca1 aBP) and Han Dynasty (2100-1900ca1 aBP) were probably the result of bronze smelting ancient people. The record of element geochemistry could identify the starting-end time of bronze smelting, and it also provided themessage on the component characteristic of bronze alloy in different periods.
Key words:  Hexi Corridor  element geochemistry  4200ca1 aBP  bronze smelting
