Agate and chalcedony from igneous and sedimentary hosts aged from 13 to 3480 Ma: a cathodoluminescence study
@article{Moxon2006AgateAC, title={Agate and chalcedony from igneous and sedimentary hosts aged from 13 to 3480 Ma: a cathodoluminescence study}, author={Terry Moxon and Stephen J. B. Reed}, journal={Mineralogical Magazine}, year={2006}, volume={70}, pages={485 - 498} }
Abstract Chalcedony and agates from a variety of world-wide hosts have been examined using cathodoluminescence (CL). Gaussian fitting of the experimental data shows that there are two dominant spectral emissions at ~400 and ~660 nm. A third subordinate peak is also found at ~470, ~560 or ~620 nm. An age-related link is shown between the respective decreasing and increasing relative intensities of the 660 and 620 nm emissions. It is proposed that this change is due to a condensation reaction…
