The results of Micro-FTIR spectra analysis of the euhedral faceted polycrystalline diamonds (EFPCDs) from the Western Yangtze Craton show that the EFPCDs are mostly IaAB type, the concentration of nitrogen.varies greatly from 25. 70- 358.

The FTIR and Raman spectra of 10 diamonds from Yuanshui, Hunan province show that the alluvial diamonds from this area are mostly IaAB type, with a significant character that the A-center is enriched relatively; the nitrogen concentration in the diamonds is between 38.20 and 840.67 microg x g(-1), which has a tremendous distinction in different crystal.

Article Synopsis
- A study of olivines from Mengyin kimberlite revealed over 60 OH absorption peaks between 3800-3000 cm(-1) using FTIR spectra analysis.
- *Four main spectral features were identified: one associated with room vapor (3800-3700 cm(-1)), and others related to non-intrinsic and intrinsic water-bearing minerals and structures.
- *The study suggests that hydrogen entered olivines through various processes, including magma immersion, and formed fluid inclusions during or after their formation in the mantle.*
