Abstract

The hydrogen content of dioctahedral and trioctahedral micas has been investigated by means of infrared spectroscopy and radioactivo measurements. Dioctahedral and trioctahedral micas have been treated with deuterium oxide and tritium-bearing water. The introduced isotopes of hydrogen have been determined after various thermal treatments.

It is concluded that dioctahedral hydrous micas may represent mixed crystals between K(Si3Al)Al2O10(OH)2 and H2O(Si3Al)Al2O9(OH)3, whereas trioctahedral micas seem to represent mixed layer minerals between phlogopite and vermiculite.
