- Title
Study of Chemical State of Iron in Giral Lignite Samples using <sup>57</sup>Fe Mossbauer Spectroscopy.

- Abstract
57Fe Mossbauer spectroscopy and powder XRD has been used to characterize the iron-bearing phase in the lignite samples collected from Giral, Rajasthan. It is found that the samples contain anomalous presence of Jarosite which is generally not found in lignite samples. Simultaneously powder XRD spectra show dominating presence of Ca2SO4 It appears that both sulphate minerals (Jarosite and Gypsum Ca2SO4) should be highly correlated. The significance of anomalous presence of Jarosite in lignite samples is discussed.
