|From the editor
One of the highlights of the GeoRaman conference was the field trip “Historic Lead Mining in Missouri” to the Bonne Terre Mine and Museum; one would expect the typical abandoned lead mine instead we visited the world’s largest fresh water dive resort!
We took a guided boat tour on the “Billion Gallon Lake” (the world’s largest subterranean lake) with its crystal clear water, and spectacular views of Underground Flower Gardens, Calcite Falls, and ancient Abandoned Mining Tools and Rail Systems.
I want to thank the organizers and helpers of GeoRaman 2014 for a memorable week in St. Louis, MO.
Please note that I will be away from the office from August 24 until September 17 while travelling in Europe.
For November several conferences/workshops are planned for Brazil including a one week seminar/field trip to the amethyst mines in Rio Grande do Sul (Porto Alegre). Please contact me regarding these events.
GL R&T was a sponsor of this well attended conference and had a display booth demonstrating the GL Gem Raman PL532 TEC and the GL Gem Spectrometers. Several researchers were impressed by their performance and versatility and are considering to purchase the Raman unit as a teaching instrument in geoscience classes.
Our poster “Raman and Photoluminescence Spectroscopy in Mineral Identification (PDF, 856 KB)” for GeoRaman 2014 was well received; the full program (PDF) with links to abstracts can be accessed here.
Of particular interest were the following contributions:
Study of the Composition of Amphiboles in the Tremolite — Ferro-Actinolite Series by Micro-Raman and SEM-EDXS (PDF) by researchers of the University of Parma, Italy, Physics and Earth Sciences Department. Several co-authors dropped by the GL R&T booth and explained their findings with a sample of nephrite using the extended range of GL Gem Raman PL 532.
Machine Learning Tools for Mineral Recognition and Classification from Raman Spectroscopy (PDF) by researchers from the School of Computer Science, University of Massachusetts, USA
Identification of CVD Synthetic Gem Diamond Using Raman Spectroscopy (PDF) by W. Wang, GIA, New York, USA
A special session in the Washington University’s Imaging lab was offered to a small group of participants. Go to GLGemRaman Facebook Photo gallery for more information.
The next GeoRaman XII will be held in Novosibirsk, Russia in 2016.
