GeneralThe Micro-World and inclusions in minerals

28th Apr 2016 19:24 UTCElise Skalwold

The Spring 2016 issue of G&G was posted today as a PDF (hardcopies are in the mail, but all is open access as well).

Our quarterly Micro-World column now features a "Quarterly Crystal" section debuting with this entry by mineralogist John I. Koivula who just gave a fantastic presentation at the recent Rochester Mineralogical Symposium (RMS):
Quartz and Lazulite http://www.gia.edu/gems-gemology/spring-2016-microworld-quarterly-crystal-quartz-lazulite

I hope everyone will follow this link to watch the embedded video in mineralogist Nathan Renfro's remarkable article (the video is not included in the hardcopy issue, though I wish an actual disc of it was bundled with the journal!). Nathan’s explanation for the phenomenon is articulated as masterfully as his photomicrography captures the scene: "A Fantastic Display of Phase Changes in a Sapphire’s Fluid Inclusion" http://www.gia.edu/gems-gemology/spring-2016-microworld-fantastic-display-phase-changes-sapphires-fluid-inclusion

Two wonderful presentations at the RMS were on radioactive minerals (Peter Burns: "The Societal Importance of Uranium Minerals and Mineral-inspired Materials" and Bob Lauf: "Mineralogy of Uranium and Thorium") which I found very interesting and informative, especially in light of studying the following inclusion. Switching my "editor hat" for my "author hat" I'm really excited that this unique analysis finally has been published after having studied and photographed this taaffeite nearly two years ago (it relates to other crystallography research currently underway): : A Halo in a Sri Lankan Taaffeite

These and the rest of the great line-up of Micro-World articles in this issue are sure to have something to appeal to everyone interested in minerals:

"Olivine in Oregon Labradorite" http://www.gia.edu/gems-gemology/spring-2016-microworld-olivine-oregon-labradorite

"Dolomite with Unusual Inclusions" http://www.gia.edu/gems-gemology/spring-2016-microworld-dolomite-unusual-inclusions

"Iridescent Inclusions in Scapolite" http://www.gia.edu/gems-gemology/spring-2016-microworld-iridescent-inclusions-scapolite

"Shrinkage “Footprint in Rose Quartz" http://www.gia.edu/gems-gemology/spring-2016-microworld-shrinkage-footprint-rose-quartz

We hope you will find all of the latest entries compelling invitations to join us in Micro-World. This is our 4th edition since the column's debut in the Summer 2015 issue and we are delighted with the great feedback and enthusiastic response.
