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.

Universities now public spaces to exercise citizenship

In an attempt to promote common understanding on governance, leadership, and management processes at the University of the Free State (UFS), the Institute for Reconciliation and Social Justice (IRSJ) recently hosted a critical conversation on the Qwaqwa Campus that was facilitated by Vice-Rector: Academic, Prof Lis Lange.

Prof Lange’s presentation firstly focused on the role that universities play, and the expectations thereof.

“From ancient history, universities have always had a critical role to play in the broader society,” she said. “They have always been characterised by the circulation of knowledge and ideas at a global level. They have always ensured that students’ skills and knowledge are properly certified.”

According to her, universities have changed quite a bit over the centuries.

“Historically, universities used to cater for the chosen few, but they now allow multitudes to have access as well. In the early 20th century, women and foreigners, for example, were excluded. How they relate to the society has also changed. They also used to create certain types of knowledge – at one stage this knowledge was influenced by the church. Research is now produced across a large spectrum of human and scientific knowledge,” she said.

Prof Lange also added that universities now even have a responsibility to advance democracy and to respond to societal needs.

“Despite the various tensions and contradictions between management and academic staff, between management and students, and between academic staff and students, universities are now public spaces to exercise citizenship. They provide space for all to have the right to speak and to be heard. They provide space for all to have similar rights and responsibilities,’ she said, while breaking down all the governance, leadership and management structures of the UFS.

The conversation was concluded with a question and answer session, with students mainly asking about internal UFS processes.

The session was well received by students.

“I really loved the conversation, which to me, was about breaking the walls between the management and students so as to achieve the goal of an effective university. We need more of these dialogues,” said Noxola Tshabalala, a BA Psychology student.
