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.

Kovsie students continue to swell the ranks of the world’s biggest academic honour society, the Golden Key International Honour Society, with more than 500 students from the university becoming new members.

The UFS chapter of the society – who only welcomes the top 15% of academic students at the university – inducted the new members at a ceremony held on Saturday 24 August 2013 on the Bloemfontein Campus.

In addition, the organisation also pays recognition to those who act as role models to these students. Thus, the organisation also inducted Profs Odireleng Ntwaeaborwa, Dave Lubbe, Dennis Francis, Pumla Gobodo-Madikizela and executive chairperson of Richmark, Gavin Varejes as honorary members.

Prof Dave Lubbe delivered the keynote speech entitled “From intellectual leader to real leader – few ideas”, structuring his talk around five key points: wisdom, basics, over specialization, ethnical leadership and courage.

“The society aims to make students realise their potential and create a network for excelling students,” said Mbavhalelo Rammbwa; Golden Key UFS Chapter president.

Parents from as far as Limpopo came to show appreciation for their children’s dedication to their studies. “I am really happy not only for my daughter, but for every single student who has been inaugurated to the society this morning for their discipline, hard work and the dedication they show their studies. I thank Prof Jonathan Jansen, the lectures and academics for inspiring our children to study and make the most of the opportunity which we didn’t have,” said Mpho Mohoje, a parent of one of the students at the induction.

Another feather in the university's cap is the fact that UFS registrar, Dr Derek Swemmer is not only co-advisor of the chapter, but also the chairperson of the society’s international governing body.
