| The prehistoric jade articles in Northeast China occupy an important position in the history of Chinese jade culture research.Geometric jade articles are one of the branches.They are based on the concept of geometric figures,and do not involve real or fictional biological characteristics.The lines are combined with straight and Fiona Fang,and their origins last for a long time.They have a wide range of interactions in distribution and distinct regional characteristics.In this paper,the geometric jades in the Neolithic Age in Northeast China are taken as the research object,combined with their archaeological culture and regional geographical characteristics,to clarify the characteristics of various geometric jades,and to do a good job for further exploring the origin and dissemination of Neolithic jade culture in Northeast China.The main work of this paper is as follows.First,the definition of Northeast China is made clear,the concept of geometric jade is introduced,and many research achievements of scholars on classification,division,staging,origin,modeling concept and so on of geometric jade in Neolithic Age in Northeast China are combed.Secondly,the unearthed situation of geometric jadeware in Neolithic Age in Northeast China was sorted out,and the shape of geometric jadeware was divided into four types: Atype jadeware with linear features,B-type jadeware with annular features,C-type jadeware with cylindrical features,and D-type jadeware with curve features.The utensils with large quantity,wide distribution,common use or unique shape were selected for sorting.Thirdly,after mastering the situation of geometric jade,according to the previous research results,the Neolithic Age in Northeast China is divided into five stages and the characteristics of geometric jade in each stage are summarized.Fourthly,the functions of A-shaped linear jade articles,B-shaped annular jade articles and jade inclined-mouth cylindrical vessels are briefly discussed.Fifthly,the conclusion of this paper is combed in the conclusion. |
