Abstract

To determine if ilmenites are stoichiometric, the ratio of ferric to ferrous ions is measured by Mössbauer spectroscopy and the oxygen content by nuclear bombardment. This latter measurement implies also the determination of the nitrogen content, if any. It was surprisingly found that the five ilmenite crystals analyzed contain nitrogen from 0.51% to 2%. These exceed the values for most other minerals. Heating experiments suggest that the nitrogen is not located in fluid inclusions. These results suggest that ilmenite could be a major reservoir for nitrogen inside the earth.
