Sulphides, Selenides, Tellurides, Arsenides and Bismuthides except the arsenides, antimonides and bismuthides of Cu, Ag and Au, which are included in Section 1 8: Hydrous and anhydrous alterations of chondrules in Kaba and Mokoia CV chondrites.
The identification of quantum effects in primitive organisms such as bacteria [1,2] has resulted in the successful application of open quantum systems models to energy and charge transfer processes in photosynthetic systems [3-5], as well as suggesting that an open quantum systems approach may contribute to an understanding of the processes by which primitive living systems emerge from the inanimate matter of which they are constituted. W A 6001, Australia. Contrasting histories of crystal-rich and crystal-poor super-sized silicic magmas.

The early partial digestion steps also remove virtually all the common Pb associated with the zircons. Beitrage zur chemischen Mineralogie, Petrographie und Geologie 30: In other cases, disturbed domains evidently reside deep within the zircons, and are attacked only when the second or third steps penetrate to the interior via cracks or flaws to mine out these domains.
Journal of Volcanology and Geothermal Research, 327, 192-207. Air-abrasion treatment of crystal fragments helps to remove internal zones influenced by metamictization and lead loss, and appears to be even more efficient if applied to fragments rather than to whole zircon grains.
