The Raman Spectroscopic Analysis on Several Nephrite Jades from Different Provenances and the Application in Non-destructive Study of Ancient Jade Artifacts
Bibliographic record
Abstract
The Raman spectroscopy are used to analyze the nephrite jades from Xinjiang,Qinghai,Jiangsu,Liaoning,Korea,Russia,Canada,New Zealand and Australian.First of all,the Raman spectroscopy can be used to identify the tremolite type nephrite jades and actinolite type nephrite jades.Secondly,the evident shift of Raman peaks in the low-frequency region reflects the chemical substitutions that typically occur in nephrite jades.Finally the relative intensity of the symmetric stretching vibration of Si-Ob-Si in 674cm-1 with the surface condition and the micro-morphology are studied separately.Based on the Raman spectroscopic study the 9 Chinese ancient jade artifacts,which were excavated from Yinxu Site of Anyang in Henan Province,Luoyang in Henan Province and Liangzhu Site of Zhejiang Province,are identified as the tremolite type nephrite jades.It is shown that the Raman spectroscopic technique is a good nondestructive approach for the identification and the investigation of the structures and the mineral composition of Chinese ancient jade artifacts.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
