Description
Summary:On the basis of x-ray and electron diffraction data and additional material bearing on crystal structure, together with recently published new data, it is proposed that although hisingerite is undoubtedly a layer silicate, it exhibits features incompatible with montmorillonite and is principally a mica with extensive substitution of Fe for Si and hydronium for interlayer alkali ions. The Fe in the tetrahedral layer would create a strained lattice and explain the poor crystallinity.
