Mineral named after UFS professor
Tredouxite (white) intergrown with bottinoite (light grey), a complex hydrous alteration product. The large host minerals are nickel-rich silicate (grey), maybe willemseite, and the spinel trevorite (dark grey).

More than five thousand minerals have been certified by the International Mineralogical Association(IMA). One of these minerals, tredouxite, was recently named after an academic at the University of the Free State (UFS). 

Tredouxite was named after Prof Marian Tredoux, an associate professor in the Department of Geology, to acknowledge her close to 30 years’ commitment to figuring out the geological history of the rock in which this mineral occurs. The name was chosen by the team which identified the new mineral, consisting of Dr Federica Zaccarini and Prof. Giorgio Garuti from the University of Leoben, Austria, Prof. Luca Bindi from the University of Florence, Italy, and Prof. Duncan Miller from the UFS. 

They found the mineral in the abovementioned rock from the Barberton region in Mpumalanga, in May 2017.

In the past, a mineral was also named after Marie Curie
With the exception of a few historical (pre-1800) names, a mineral is typically named either after the area where it was first found, or after its chemical composition or physical properties, or after a person. If named after a person, it has to be someone who had nothing to do with finding the mineral.

Prof Tredoux said: “As of 19 September 2017, 5292 minerals had been certified by IMA. Of these, 81 were named after women, either singly or with a near relation. Marie Curie is named twice: sklodowskite (herself) and curite (plus husband). Most of the named women are Russian geoscientists.”

Another way to assess the rarity of such a naming is to consider that fewer than 700 minerals have been named after people. Given that there are by now seven billion people on the planet, it means that a person who is granted a mineral name becomes one in 10 million of the people alive today to be honoured in such a way. To date, over a dozen minerals had been named after South Africans, three of them after women (including tredouxite).

It contains nickel, antimony and oxygen
The chemical composition of tredouxite is NiSb2O6 (nickel antimony oxide). This makes it the nickel equivalent of the magnesium mineral bystromite (MgSb2O6), described in the 1950s from the La Fortuna antimony mine in Mexico.  

“This announcement is of great academic importance: the discovery by the Italian team of a phase with that specific chemical composition will undoubtedly help me and my co-workers to better understand the origin of the rock itself,” she said. She also expressed the hope that it may raise interest in the Department of Geology and the UFS as a whole, by highlighting that world-class research is being done at the department. 

The announcement of this new mineral was published on the International Mineralogical Association Commission on New Minerals, Nomenclature and Classificationwebsite, the Mineralogical Magazine and the European Journal of Mineralogy.

UFS DiMTEC will help compile national emergency management system

Description: UFS DiMTEC will help compile national emergency management system Tags: UFS DiMTEC will help compile national emergency management system

Preparedness and response are the two most important aspects of managing disaster when it strikes. Prof Andries Jordaan, Head of the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS) recently attended an incident command course in California in the US.

Learning from US disaster management systems
More than 20 specialists from 17 countries attended the course where participants were introduced to the National Incident Management System (NIMS) in the US. The system was implemented after lessons learned during 9/11. “According to the NIMS structure, all government organisations at all levels as well as emergency agencies had to standardise terminology and systems,” said Prof Jordaan.

The professor also had the opportunity to visit among others the Federal Emergency Management (FEMA) headquarters in California, some State Coordination Centres as well as several other disaster management centres. He also had the chance to shadow an Incident Management Team (IMT) during active operations.

Providing training for local disaster management
Insight gained during this course, as well as Prof Jordaan’s experience as senior officer in the South African National Defence Reserve Forces, provided him the necessary background to conduct training and give assistance in terms of disaster management.

Through DiMTEC Prof Jordaan will assist the National Disaster Management Centre with the implementation of a national emergency management system. He will also provide training for incident management teams.

“DiMTEC is currently also in the process of developing a Master module in disaster response. Command and control and Incident Command will form a sub-module in the disaster response module,” he said.

From South Africa, Prof Jordaan was joined on the course by General Elias Mpumelelo Mahlabane from the South African Police Services, who is responsible for disaster management in the SAPS. Savage Breytenbach, a trainer in rural fire fighting who assists Mangaung with command and control structures, also attended the course.
