Abstract:Microscope, LA-ICP-MS, (Micro)FT-IR, UV-Vis, Raman and other methods were used to analyze conventional gemology, chemical element content and spectral features of Pakistan peridot, so as to discuss its origin characteristics. The result shows that Pakistan peridots contain black Vonsenite-Ludwigite needle and punctiform msgnetite. Compared with peridots from the USA, China, Ethiopia, Vietnam and Madagascar, Pakistan perdots have higher Li, B, Sc but lower Zn, Cu, with relatively lower V/Sc ratio. The absorption bond around 3 580 cm-1 in the infrared absorption spectrum of peridot in Pakistan is related to the [Si]=(4H)SiX substitution mechanism, indicating that the crystal structure contains a certain amount of structural water. The strong absorption near 380, 450, 490, 635 nm in UV-Vis spectrum is related to O2-→Fe3+ transition, 6A1→4A1+4E(4G)in d-d transition of Fe3+ and 5T2g→3T2, 5T2g→3T1g electron transition of Fe2+. It is concluded that inclusion, trace element and structural water-induced infrared absorption band can be used as the origin identification characteristics of peridots in Pakistan.
