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.

Colloquium focuses on rural education
2012-10-10

Some of the international delegates during the second annual colloquium on rural education recently held at the Qwaqwa Campus.
10 October 2012

 The second edition of the Sustainable Rural Learning Ecologies (SuRLEc) Colloquium was held at the University of the Free State's Qwaqwa Campus this week. This three-day international event provided the Faculty of Education's postgraduate students with a platform to present their research and to learn from experienced researchers from all over the world.

In his opening address, the Faculty's Programme Head, Dr Dipane Hlalele, challenged all delegates to translate their research into achievable goals to address all the challenges facing rural education.

"Excellence in teaching and learning in a rural context remains a challenge for all sectors and levels of the education endeavour," Dr Hlalele said.

"Urban and metropolitan schools, colleges and universities may unintentionally structure their learning programmes in such a manner that they neglect rural attributes. This results in the marginalising of learners and students from rural environments. To complete the loop, these institutions are more likely to fail in preparing graduates for decisive contributions to sustainable rural learning ecologies," Dr Hlalele added.

The colloquium was officially opened by the Vice-Rector: External Relations, Dr Choice Makhetha, who highlighted the fact that the UFS was already doing its bit in levelling the learning playfields in higher education.

"We are aware that many of our students who come from disadvantaged backgrounds find it hard to cope at university. As a result, we are not waiting for them to come through to us. We are already in partnership with a number of schools where we help learners to improve their results," Dr Makhetha said.

The crucial role played by rural teachers was celebrated during a gala dinner to honour and acknowledge their efforts despite a myriad of daily challenges.

Ms Jabulile Mabaso (The Mills Primary Farm School) was honoured for 'Excellence in multi-grade teaching in Foundation and Intermediate phases'. Ms Rekha Mathew (Sibonakaliso Primary Farm School) and Mr Andries Motsoere (Tshebedisano Primary Farm School) were awarded for 'Excellence in managing multi-grade curriculum'.

The 2012 SuRLEc Honorary Award went to Ms Motshedisi Damane for her valuable contribution to the development of rural education in the Thabo Mofutsanyana Education District. Last year's recipient was the Dean of the Faculty of Education, Professor Dennis Francis.

Delegates and keynote speakers came from Thailand, Malaysia, the Unites States of America as well as the SADC countries of Botswana, Zimbabwe and Lesotho. South Africa was represented by the Universities of the North-West, Limpopo, KwaZulu-Natal and CUT, amongst others.
