Digitalization and Traceability of Qijia Culture Jades

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.
