摘要
对内蒙古赤峰市敖汉旗大甸子墓地出土57件铜器中的41件耳环,指环等进行检测,其中的11件进行了取样金相鉴定和扫描电镜能谱分析,另外30件进行了表面扫描电镜能谱分析。所有被检测器皆为青铜制成,使用了铸造和热锻加工技术、检测还表明该批铜器的制造者已经能够根据制作要求控制锡含量,由此可以断定制造该批铜器的铜料和锡料应是分别生产的。大甸子墓地出土的含锡约10%的铅合金制品以及含钨的铁矿石颜料表明,锡科可能来源于西拉木伦河北岸铅锡多金属成矿带。
Examinations have been made on 41 earrings and finger rings out of the 57 bronzes from the tombs of the Lower Xiajadian culture at Dadianzi, Aohanqi, Chifeng, Inner Mongolia. 11 were made into polished section for microscopic testing while the rest just polished at surface for SEM analysis. Casting and heat forge techniques were employed. Examination shows that the ancient workers could control the tin content. Copper and tin seems to have been produced separately. Several copper mines have been found nearby and shown traces of exploitation. However, no tin source has ever been found around. Those bronzes with a tin content at 10% and iron ores containing tungsten unearthed in the same cemetery seem to be from the northern bank of the Xilamulun River, an area abundant with tin vines.
