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.

 Prof. Jonathan Jansen, Vice-Chancellor and Rector of the university, recently addressed six Ph.D. students and their supervisors in the Faculty of Law as part of a special programme of the Postgraduate School for emerging researchers. Prof. Jansen contextualised his lecture on the impact and significance of research, “How do you determine that the important and bigger questions in your research are addressed to ensure the impact thereof?” in his discussion with the researchers. Based on the model of international postgraduate seminars, the researchers set out their field of study to Prof. Jansen and the audience. Suggestions were then made on how to increase the intellectual impact and theoretical depth of academic argumentation.

According to Prof. Neil Roos, Director of the Postgraduate School, together with Prof. Jackie du Toit and Prof. Corli Witthuhn, Academic Coordinators for the Vice Chancellor’s Prestige Scholar Programme, the aim of the programme is to provide support to emerging researchers on postgraduate level similar to the Prestige Scholar Programme.

“The initiative is being rolled out in a faculty-specific way. In consultation with the deans, the specific needs in the faculty are determined, which in turn determines the approach,” says Prof. Roos.

The six students are all involved at the university in various capacities, and are studying towards a Ph.D. in Law. They are outstanding candidates who are being funded by the Postgraduate School in order to empower postgraduate students to greater reach, internationalisation and the establishment of long-term academic networks. The programme is coordinated in the Faculty of Law by Prof. Loot Pretorius.

Two upcoming researchers in the Faculty of Theology and one in Nursing joined the group for Prof. Jansen’s lecture on significant research.
