Abstract
DURING the past few years there has been active interest in the problem of alternative explanations other than layers of different composition in the Earth to explain seismic data. The most important of these arises from an early suggestion by Bernal1 regarding the possible inversion of the orthorhombic mineral olivine to a dense form with the spinel structure. An actual example of this inversion from the spinel to the olivine had been reported by Goldschmidt2 for the compound Mg2GeO4. However, there have always been some doubts regarding this observation, since it was mentioned only in a footnote and could not be repeated.
