The book "Applications of Mössbauer Spectroscopy in Mineralogy" offers a comprehensive analysis of the application of Mössbauer spectroscopy in mineralogy and planetary science. The authors Jozef Sitek, Katarína Sedlacková, and Július Dekan highlight the significance of iron content in mineralogical objects and their investigation through this specialized technique. Mössbauer spectroscopy has established itself as a valuable analytical tool in the Earth sciences, providing detailed information about the oxidation and magnetic states of iron in minerals. By precisely characterizing the valence state of iron, mineralogists can address current challenges in natural inorganic systems and develop solutions. This specialized book is aimed at scientists and students engaged in mineralogy and related analytical methods.
