SummaryCommon chalcedony and agate, when examined by methods of investigation similar to that employed in the case of iridescent agate, the results of which have already been reported in theseProceedings, exhibit analogous features. The transmission and diffusion of light, their polarisation characters and the influence of the thickness of the medium on these features are discussed from a theoretical standpoint. The results are borne out by observations made with several specimens of agate and… 

On the optical behaviour of crypto-crystalline quartz

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

Structural defects in microcrystalline silica

The structure of the microcrystalline silica varieties chalcedony, flint, moganite, opal-C and -CT is characterized by X-ray powder diffractometry and transmission electron microscopy (TEM). The role

X-ray study of fibrous quartz

5. SummaryThe results of optical and X-ray examination of specimens of fibrous quartz from the Bababudan Hills in Mysore are described. They indicate that the material may be described as

Molecular and X-ray Spectroscopies for Noninvasive Characterization of Mayan Green Stones from Bonampak, Chiapas

The main features of the molecular and X-ray techniques are compared in order to determine the advantages and limitations of these spectroscopies for mineral identification to undertake a suitable characterization of the analyzed objects.

Über die natürlichen Faser- und Aggregationstypen beim SiO2, ihre Verwachsungsformen, Richtungsstatistik und Doppelbrechung

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


The theory of the Christiansen experiment

SummaryThe effects exhibited by a Christiansen filter can only be explained or understood in terms of wave-optics. A theoretical formula is derived in the paper for the distribution of intensity in
