Data for: Ceramic production in prehistoric northwest China: preliminary findings of new analyses of old material from the Museum of Far Eastern Antiquities, Stockholm

Appendix A contains the results of the petrographic analysis of 11 thin section samples taken from 10 ceramic sherds from 3 prehistoric sites in Gansu, northwest China, i.e., Majiayao, Qijiaping, and Xindian. The analyses were conducted using petrographic microscopy using plain and cross-polarized light. The results are summarized in a table format in Appendix I and as data sheets with photographs in Appendix AII.

Appendix B contains the results of portable ED-XRF analysis with an Olympus Delta 50 portable XRF. A meassuring spot of 5 mm and 60 seconds measuring time were chosen. Three measurements each were taken on fresh, clean breaks, avoiding larger conclusions were visible. The mean values of the three value sets were taken. The results are displayed in a table format.

附录A收录了中国西北甘肃省3处史前遗址（即马家窑、齐家坪、辛店）出土的10件陶瓷残片的11件薄片样品的岩相分析结果。本次分析借助岩相显微镜，采用单偏光与正交偏光两种照明模式开展。结果以表格形式汇总于附录I，并以带照片的数据表形式收录于附录AII。

附录B收录了采用奥林巴斯（Olympus）Delta 50便携式X射线荧光光谱仪开展的便携式能量色散X射线荧光（ED-XRF）分析结果。本次测试选取了5mm的光斑尺寸与60秒的测量时长，每次均在新鲜洁净的断裂面进行三次测量，避开存在可见较大缺陷的区域，并取三组测量值的平均值作为最终结果。结果以表格形式呈现。
