Abstract
Raman and infrared spectroscopy are fast, simple and useful methods of identifying and distinguishing between different rock samples, which often originate from different sources. We analyzed nephrite samples from Polish deposits (Zloty Stok in the Sudetes and Jordanow Slaski in the Fore-Sudetic Block). Studied nephrites amphiboles, with the general formula (Ca-2(Mg,Fe)(5)Si8O22(OH)(2)), magnesium and iron contents, in terms of Fe/(Fe+Mg) per formula unit, are as follows: Jordanow S1aski (0.06-0.10), Zloty Stok type 1 (0.10-0.20) and Zloty Stok type 2 (0.04-0.18). Our spectroscopic study is consistent with results of previous petrographic microscopy, scanning electron microscopy and chemical composition of constituting minerals, measured by the electron microprobe; which methods were applied to the same nephrite deposits. Results of Jordanow and Zloty Stok nephrites studies were compared with data available in literature, which confirmed petrographic composition of studied samples. In addition, in case of actinolite nephrite samples (Fe/(Fe+Mg) > 0.10), qualification of the studied minerals to actinolite with content of Fe ion below 15% and 30% in sample from Jordanow Slaski and Zloty Stok, respectively, is possible based solely on applied spectroscopic methods. Spectroscopic studies also allowed to note the relationship between the obtained results and the genetic origin (serpentinite-related or dolomiterelated) of the studied nephrites. Findings confirmed that spectroscopic methods are not only applicable and useful, but, which is very important in gemological and archaeometric practice, also non-destructive. (C) 2018 Elsevier B.V.
