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.

The Institute for Reconciliation and Social Justice (IRSJ) marked its fifth anniversary with a function on 27 July 2016 in the Reitz Hall of the Centenary Complex on the Bloemfontein Campus of the University of the Free State (UFS). Earlier that day, the Advisory Board of the IRSJ, chaired by Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS, hosted their annual meeting.

A new book was also launched, co-authored by JC van der Merwe, Deputy-Director at the IRSJ and Dionne van Reenen, researcher and PhD candidate at the IRSJ. It is entitled Transformation and Legitimation in Post-apartheid Universities: Reading Discourses from ‘Reitz’. The function featured not only reflections on the IRSJ, but a four-member panel discussion of the book and higher education in 2016.

The IRSJ came into being officially at the UFS in January 2011. Prof André Keet, Director of the IRSJ, said: “With a flexibility and trust not easily found in the higher education sector, the university management gave us the latitude and support to fashion an outfit that responds to social life within and outside the borders of the university, locally and globally.”

The IRSJ has not hesitated to be bold and
courageous in reforming ... traditional policies."

 

Prof Jansen went on to mention three things he finds appealing about the IRSJ: “Thanks to Prof Keet and his team’s vision and understanding of how important it is for students to have a space in which they can learn how to be, learn how to think, and learn how to contribute, the IRSJ has become a place where students can learn about things that they might not learn in the classroom. Second, it created, for the first time, a space where members of the LGBTIQ community could gather in one place. And third, it speaks to the intellectual life of the university, as evidenced by the research and publications produced over the past few years.”

Prof Jansen added: “The IRSJ will only be successful to the extent that we have safe spaces, courageous spaces, in which not only black students talk to themselves, but where black and white students talk together about their difficulties. If you’re entangled, you can’t get out of [that] unless you speak to the other person.”

Prof Michalinos Zembylas of the Open University of Cyprus and member of the Advisory Board, said of the IRSJ: “The works produced by the institute in this short time have been valuable to this community and beyond, because they recognise the complexities of education, ... while pushing the boundaries of how to translate theoretical discussions into practical, everyday conditions. ... For example, the IRSJ has not hesitated to be bold and courageous in reforming some traditional policies in this university—remnants of an ambivalent past that reproduced inequality and disadvantage.

In reflecting on how the IRSJ came into being during her opening remarks, Dr Lis Lange, Vice-Rector: Academic at the UFS, said that it has always been “dedicated to transformation.” She added that it “gathered the energy and creativity of some of our most promising student leaders.” She concluded: “For me, the greatest success of the Institute, besides publications and local and international networks, is the fact that something that started in the margins is being asked today to come closer to the centre, to play a larger role in the structural transformation of the university.”
