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.

Phiwe Mathe and Matlogelwa Moema, both third year students, have been elected as presidents of the 2013/14 Student Representative Councils (SRC) of the University of the Free State’s Bloemfontein and Qwaqwa Campuses respectively. They now also serve as the presidency of the Central SRC and will take up their seats as voting members of the UFS council in September 2013. Thirty-eight candidates contested the 19 elective seats of the campus SRCs, for which 83 nominations were received.

Rudi Buys, Dean of Student Affairs, announced the completion of the elections at the two campuses as successful.Buys deemed the elections highly significant, considering it is the third year of peaceful elections since students adopted changes in student governance in 2011. These changes included, among others, the introduction of independent candidacy for elective portfolios and organisational candidacy in SRC sub-councils that hold ex-officio seats on the campus SRC. Changes also included the establishment of student representative seats in faculty forums and the adoption of reviewed SRC constitutions, Buys said.

The SRC elections at the Qwaqwa Campus were completed on 23 August 2013, while the elections at the Bloemfontein Campus took place on 26 and 27 August 2013. Elections at the Qwaqwa Campus showed a voter turnout of 44% and at the Bloemfontein Campus a turnout of 31.5%, which is among the highest in the country.

Both campuses reached the required quorums and the campus elections bodies, the IEA (Bloemfontein Campus) and IEC (Qwaqwa Campus), declared the elections free and fair and announced the results as a true reflection of the will of the student bodies at the campuses.

This year also saw the piloting of a central SRC elections oversight committee (CEC) to strengthen independent oversight of all elections. The CEC monitors the elections as free, fair and democratic and consists of senior academics and former student leaders of the Student Elders Council. Prof Loot Pretorius, inaugural chair of the CEC, announced the CECs confirmation of the SRC elections across campuses as free, fair and democratic.

Celebrations marked a mass meeting on the Bloemfontein Campus where the new student leaders were announced on Thursday 29 August 2013. There were cheers and singing as Quintin Koetaan, Head of the Bloemfontein IEA, on behalf of the two elections bodies, read the names of the newly-elected student leaders of both campuses. Delivering his victory speech, Phiwe thanked competitors for running a good debate, saying it was not about characters or personalities, but rather the ideas that would best serve a Kovsie. “Students will remain central and the ‘R’ is back in SRC,” he told the resounding crowd. Matlogelwa reiterated this message and said, "the SRC is for students and will serve all students equally."

Following on the heels of the SRC elections, voting for residence committees will take place next week with 618 candidates contesting 231 available positions. The elections of association executive committees will also take place in September.
