MÖSSBAUER STUDIES OF ICELANDIC LAVAS
Two samples of lava from Iceland have been studied by use of Mössbauer spectroscopy. It is found that a hi& rate of solidification leads to smaller quadrupole splittings of the ferrous doublets. One of the samples contains superparamagnetic particles. The olivine Fe0.34Mg1.66SiO4 becomes magneti...

Summary: | Two samples of lava from Iceland have been studied by use of Mössbauer spectroscopy. It is found that a hi& rate of solidification leads to smaller quadrupole splittings of the ferrous doublets. One of the samples contains superparamagnetic particles. The olivine Fe0.34Mg1.66SiO4 becomes magnetically ordered between 5 K and 11 K. |
