采用PIXE、EDXRF、穆斯堡尔谱和XRD等技术对采自印度奥里萨邦Moulabhanj的两个典型含钛磁铁矿样品进行了研究。穆斯堡尔谱和XRD分析表明，样品中主要含铁物相为磁铁矿、赤铁矿、亚铁钛铁矿和铁钛铁矿。根据穆斯堡尔谱的共振面积确定了Fe ~（2+）/Fe ~（3+）比值和不同矿物的相对百分含量。采用能量色散X射线荧光（EDXRF）和质子激发X射线荧光（PIXE）进行多元素定量分析。19个次要和微量元素已被定量EDXRF，而PIXE的18个元素已被定量分析。利用EDXRF和PIXE测定的微量元素浓度，对沉积盆地的物理化学条件进行了解释。
Two representative titaniferous magnetite samples procured from Moulabhanj, Orissa, India have been studied by PIXE, EDXRF, Mössbauer spectroscopy, and XRD techniques. Major iron-bearing phases identified in the samples by Mössbauer spectroscopy and XRD are magnetite, hematite, ferrous ilmenite and ferric ilmenite. The Fe2+/Fe3+ratio and the relative percentages of different minerals were determined from the resonance areas of Mössbauer spectra. Quantitative multielemental analysis was carried out by energy dispersive X-ray fluorescence (EDXRF) and proton induced X-ray emission (PIXE). Nineteen minor and trace elements have been quantified by EDXRF whereas by PIXE eighteen elements have been analyzed quantitatively. Concentrations of trace elements determined by EDXRF and PIXE were used in interpreting the physico-chemical condition of the depositional basin.
