2011 Mineralogical Society of America Short Course

We direct your attention to a Mineralogical Society of America short course on “Sulfur in Magmas and Melts and Its Importance for Natural and Technical Processes ” to be held in Goslar, Germany, on August 21st – 23rd, 2011 – immediately after the 2011 Goldschmidt Conference. This course will bring together experts in relevant geological and geochemical fields with those in the technical glass industry and glass sciences, and we invite interested students and professionals to attend.

The short course will involve lectures based on the 15 chapters of the Reviews in Mineralogy and Geochemistry volume 74 on this broad subject (see details below). The course will also include a poster presentation session for students on August 21st.

Two extensions of the short course are offered to students, including two practical courses; details included below. The practical courses are limited to 36 participants.

Dates: Short Course sessions are Sunday through Tuesday, August 21-23, 2011 (following the Goldschmidt Conference 2011 in Prague). The Short Course will start at 9:00 AM on Sunday, August 21, and end 5:30 PM the evening of Tuesday, August 23rd. An introductory ice-breaker celebration will be held 7:00 PM on Saturday, August 20. The historical mining at the UNESCO World heritage site at Rammelsberg ( will be visited on August 22.

A summer school is offered to students and young researchers which includes the short course at Goslar andtwo practical courses on August 20 in Hannover, Germany, and on August 24 in Clausthal, Germany.

Location: Short Course sessions are at the Hotel der Achtermann, Rosentorstrasse 20, D-38640 Goslar, Germany; Tel: +49 5321/7000–0; Fax: +49 5321/7000–999; E-Mail (for reservations): The short course location can be reached within two hours from the airport Hannover-Langenhagen, Germany, with a change of the train at Hannover Central Station. From the railway station in Goslar you go about 200 m to reach the conference hotel which is located near the historic center of Goslar. Participants who come by car have to note that parking lots are rare in the environment of the hotel. An option is the parking garage Am Zentrum nearby the hotel which has currently a charge of 9 € per night.

Short Course Description: Sulfur is one of the most abundant volatiles in terrestrial magmas, and it plays key roles in processes of magma evolution, volcanic degassing and eruption, metasomatism and mineral deposit formation, and atmosphere evolution. During large volcanic eruptions, massive amounts of sulfur are released, mostly as SO2, which have important climatic impacts. Sulfur is also an important component of processes used to manufacture high-quality glasses and steel for industry. In recent decades, various new investigations were started in the geosciences and material sciences using modern spectroscopic, analytical, and experimental techniques in order to improve our understanding of the complex behavior of sulfur in natural and synthetic melts, but these different research initiatives were often not interconnected. One of the major goals of this course is bridging the gap between research on sulfur in melts in earth science and in material sciences. In addition to exchanging information and ideas, the purpose of the short course is to serve as a forum for discussion of future research tasks and initiatives.

Short course attendees will learn and discuss:

  1. Modern methods for analyzing sulfur concentrations, isotopes, speciation, and coordination in glasses, minerals, rocks, and fluids.
  2. Rates of sulfur diffusion and details on oxidation-reduction reactions involving sulfur in a broad variety of melts.
  3. Kinetics of melting raw materials for industrial glass production.
  4. The determination of sulfur solubility in commercial molten glasses and in the broad variety of magmatic melts and sulfur solubilities as a function of melt composition, oxygen fugacity, pressure and temperature.
  5. Sulfur partitioning between geologically relevant melts and chemically simple to complex fluids comprised of C-O-H-S-Cl.
  6. The identities and importance of sulfur-bearing minerals in magmatic systems.
  7. The role of sulfur in extraterrestrial bodies and in magmatic processes of the deep Earth.
  8. The crucial role of sulfur for fining of molten commercial glasses and the related redox reactions.
  9. Sulfur degassing from volcanoes with respect to source conditions in the magma, the surveillance of volcanic activities, the chemical composition of released gases, and global impacts of volcanic sulfur release.
  10. Application of sulfur’s stable isotopes to the study of magmatic and hydrothermal processes in natural systems.
  11. Use of slag to sequester sulfur from molten steels to produce high-quality metals.
  12. The crucial role of sulfur in the evolution of magmas and related processes of concentrating, transporting, and depositing a wide variety of chalcophile ore metals.

Field Trip: The historical mining at the UNESCO World heritage site Rammelsberg ( will be visited on August 22. The transport from the conference to the mining site is by bus and no special attire is required for visiting the mining.
