SummaryThe polarisation of the light regularly transmitted by fibrous chalcedony and the character of the diffraction spectra exhibited by iridescent agate are described and discussed. It is shown that the phenomena point conclusively to the laminations in iridescent agate responsible for the diffraction effects being a consequence of the periodic orientation of the c-axis of quartz along the length of the fibres. Photographs illustrative of the optical effects and of the X-ray diffraction…

Die bis jetzt sicher bekannten Fasertypen [11$0], [0001], [1010] bei Quarz sind auf Grund ihrer abnehmenden Haufigkeit wahrscheinlich strukturbedingt durch Ketten abnehmender Bindungsstarke in diesen
