青海都兰县塔温搭里哈遗址铜器的初步科学分析

Preliminary Scientific Study of Bronze Artifacts from Tawendaliha Site in Dulan County of Qinghai Province

青海都兰县塔温搭里哈遗址是一处重要的诺木洪文化遗址,属于甘青地区晚期青铜时代遗址。对遗址的37件铜器进行了SEM-EDS和金相检测分析。结果显示,铜器有红铜和铜锡合金两种材质,红铜残器有19件,铜锡合金残器有17件;铜器加工工艺有铸造、铸后热锻、铸后冷加工等工艺,铜刀等工具类铜器都使用了铸后热锻或冷加工工艺,其它铜器为铸造工艺。这是首次对诺木洪文化铜器进行分析检测,可为研究诺木洪文化铜器的制造技术提供依据,进而为探讨甘青地区晚期铜器的技术及其发展变化提供依据。

The Tawendaliha site in Dulan County,Qinghai Province is an important site of Nomuhong culture,which belongs to the late Bronze Age site in Gansu-Qinghai area.37 bronze artifacts from Tawendaliha site were in preliminary examination by SEM-EDS and metallographic examination.The results show that these samples include 19 red copper and 17 Cu-Sn alloys.Processing technologies of bronze artifacts include casting,hot forging after casting,and cold processing after casting,etc.The tool bronze artifacts such as copper knife were made by hot or cold forging after casting,other bronze artifacts were made by casting.This is the first time that the bronze artifacts of Nomuhong culture are scientifically analyzed.This study can provide a basis to study manufacturing technology of bronze artifacts of Nomuhong culture.
