The Hetian Yu from Maxianshan have important gemological and archaeological cultural value in Gansu province. The origin discrimination is divided into a research focus for Hetian Yu from Maxianshan. In this paper, through testing and analyzing chemical compositions of Hetian Yu from Maxianshan, comparing its chemical compositions with the main domestic origins of Hetian Yu, and establishing discriminant models for the origins of trace elements, it explores the identifications of Hetian Yu from Maxianshan in Gansu and providing data supports for the traceability of ancient jade artifacts of the Qijia Culture in Gansu. Electron probe analysis of the main elements of Hetian Yu from Maxianshan shows that main component is tremolite. The trace elements and REE of Hetian Yu from Xinjiang, Qinghai, Liaoning, Jiangsu, Guizhou and Gansu provinces were analyzed by laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS), and show that there were differences in the trace elements, REE parameters and the REE distribution patterns of Hetian Yu from Maxianshan with other origins, which could be used to discriminant Hetian Yu from different origins. Three-dimensional scatter map ΔCe-Σ REE-LREE/HREE can discriminant the origins of Hetian Yu from Qinghai, Liaoning, Jiangsu and Guizhou provinces but can not discriminant the Hetian Yu from Xinjiang and Gansu provinces. SPSS software was used to establish a linear origin discrimination model for trace elements of Hetian Yu in Maxianshan, Xinjiang Uygur Autonomous Region, Qinghai, Liaoning, Jiangsu, Guizhou provinces. For six known origins: Xinjiang Uygur Autonomous Region, Qinghai, Liaoning, Jiangsu, Guizhou, Gansu provinces, the correct rate of discriminant analysis and cross-validation can reach 100.0% and 90.3%. There are 10 sets of Maxianshan data reserved, and the correct rate of back-generation verification is 100%. The linear origins discrimination model of trace elements has a good effect in the discrimination of Hetian Yu from various origins.
