齐家文化玉器数字化与玉料产地溯源

Digitalization and Traceability of Qijia Culture Jades

摘要:

对同济大学博物馆展出的甘肃8家博物馆馆藏的代表性齐家文化玉器进行了数字化处理研究，并对采自于甘肃马衔山的软玉玉料，使用现代大型仪器对其矿物组成、显微结构、化学成分等进行检测分析。利用齐家文化玉器数字化处理研究所获得的实物史料信息，通过对比齐家文化玉器风化层与马衔山软玉风化层及蚂蚁脚（次生矿物）在结构和表生埋藏环境方面的相似性，判断甘肃马衔山软玉为齐家文化玉礼器所用材料的一个重要产地来源。

Abstract:

Some representative jade wares of Qijia Culture from eight museums in Gansu are digitized. Meanwhile， the mineral composition， microstructure， and chemical composition of Maxianshan nephrite are tested. Based on the digitized information of jade wares of Qijia Culture， the similarities in the weathering layer and supergene burial environment reflected by secondary minerals between jade wares of Qijia Culture and Maxianshan nephrite are compared. It is concluded that Maxianshan nephrite is an important origin source of jade materials used in Qijia Culture.
