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 unveils portrait of Ms Winkie Direko  
A portrait of Ms Winkie Direko, former Chancellor of the University of the Free State (UFS) and Premier of the Free State Province and currently a Member of Parliament, was unveiled today during the last session of the UFS Council for this year on the Main Campus in Bloemfontein.

The portrait, painted by the gifted artist Ms Reshada Crouse, now hangs in the Council Chambers of the UFS.

Ms Direko was sworn in as Chancellor of the UFS in August 1999.  She was the first black person and first woman in this position at the UFS. She was succeeded by Dr Franklin Sonn.

“Ms Direko had an exceptional legitimacy in the black community because of her role in black education in the Free State (as principal) and community leader in the difficult ‘struggle’ period.  This former principal’s simultaneous insistence on transformation as well as discipline and order at an educational institution was exactly what the UFS needed at that stage,” said Prof Frederick Fourie, Rector and Vice-Chancellor, during the unveiling ceremony.

“She also played a special role to bring the UFS and the Free State Provincial Government closer to each other.  Her comprehension for the own nature of a university helped in times when difficult decisions had to be made.  She also realised the value of the university’s expertise for her government.  The Premier’s Economic Advisory Council, with the UFS rector and academics like Lucius Botes and James Moses in leading roles, was formed to undertake important research on economic development strategies in the Free State,” said Prof Fourie.

In her speech Ms Direko said that it is an unique experience for her to be catalogued in the history of the UFS.  “I am humbled and proud to be associated with the UFS,” she said.

Ms Direko said that the UFS is on the right track with its transformation process.  “I will continue to convince people that the UFS is for everyone and will fight for that until the end.  But, it is important to see a visible change concerning transformation.  The UFS must bring its side and speed up the transformation process.  I know that it is a difficult road, but we cannot hide from the realities of our time,” she said.
