Many reagents have been used for the photometric determination of small amounts of thorium, the most favoured being "thorin"1, also known as "thoron", "APANS", and by several other names. The reaction of thorium with thorin, as with other reagents, is not selective, and rather complete separation of

## Limitations of resolution and absorption in standard chemical spectroscopic techniques have made it difficult to study fluids in sedimentary rocks. In this paper, we show that a chemical characterization of pore fluids may be obtained in situ by magic angle spinning (MAS) nuclear magnetic reson
