内蒙赤峰翁牛特旗尖山子冶炼遗址考察

对内蒙古自治区赤峰市翁牛特旗尖山子冶炼遗址开展田野考察和实验室检测。先后两次田野考察采集到陶片、炉渣、矿石等遗物,认定遗址面积约为1万多m2。矿石、炉渣的检测显示该遗址使用尖山子矿区含铜锌为主的共生氧化矿石还原冶炼生产红铜,因矿石含有较高的锌矿物,因而形成含锌较高的炉渣。综合伴生陶片类型等信息,初步判断尖山子冶炼遗址年代属于夏家店下层文化时期。对围绕该遗址的进一步工作提出建议与展望。

Investigation on Jianshanzi Smelting Site in Wengniuteqi of Chifeng of Inner Mongolia

The field investigation and laboratory determination are conducted on the Jianshanzi smelting site(N42°52′31.9″,E119°12′7.2″) located in Wengniuteqi(Ongniud Banner),Chifeng Prefecture of Inner Mongolia.From the discovery of the clay fragments,slag and ores in twice field researches,the smelting site is about 10 000 m2 in area.The analyses on the ore and slag samples show that at the smelting site,the pure copper was smelt by using the Cu-Zn coexisting ores mined from the Jianshanzi deposite.The slag system is of the high ZnO content in the smelting process because of the high content of zinc in the ore.By comprehensively analysis of the clay fragment information etc,the Jianshanzi smelting site is primarily recognized belong to the Lower Xiajiadian Culture,the first bronze culture in North-east China dated as early as 4 200~3 600BC.The suggestion and prospect for further works on Jianshanzi smelting site are put forward based on the investigation.
