Abstract:
The present thesis reports some investigations carried on natural samples namely Ochres, goethite and bog iron ore; Iron Ores; and chromites. Main tool of the study was Mossbauer spectroscopy in which the probe was 14.4 KcV gamma-rays of Fe57 radioactive source. Chemical, differential thermal and infrared absorption analyses were also done in some cases to support the results. Thin and polished section studies were done to identify the minerals in case of iron ore and chromite samples. Its subject matter has been divided in following chapters:
Chapter 1 -
After comparing the advent of Mossbauer effect with those of others,the former has been defined and its suitability has been discussed. A brief review of the previous work and its applications have been given. Labtly, the motivation behind the problem, pursued, has been elaborated...
