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.

Open Day attracts thousands

“It is easier to pass Grade 12 today because we don’t have a standard. However, at the University of the Free State, standards are important.”

This was Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS’ message when he addressed a packed Callie Human Centre on the Bloemfontein Campus during this year’s Open Day.

“This university is the jewel of the country. Here at Kovsies we take academic standards seriously. You must know who you are in a place where academic standards are extremely important. Anyone can obtain a degree, but here you can get more than a degree. You get an education,” he said to the more than 5 000 learners and parents from across the country.

“It is not only important that you study here in South Africa, but also in other countries. That is why our students study all over the world. You must think out of your comfort zone, have a big heart, achieve great heights and show everyone that you are a Kovsie.

But, it is not all about studying – it is also about being human and reaching out to others. When you come to this university, you will also do other things that will make you proud of being a Kovsie.

Quality looks for quality. Therefore, work hard and study hard because you need to be at a good university,” he said.

The programme consisted of, among others, a spectacular laser show, a performance by Bobby van Jaarsveld and special messages from DW Bester and Sannah Mokone, Rhodes Scholars currently studying at Oxford University in the United Kingdom.

In a pre-recorded message DW, a Ph.D. student in Mathematical Statistics, encouraged prospective students to work hard and persevere. Sannah, doing a Master’s degree in African Studies, said she believes in the future of the African continent. “I believe in our future students and know you can make it.”

Prof. Jansen also introduced some of the university’s recent student achievers such as Jurie Swart, regional winner of the Corobrik Architectural Student of the Year Award; Farzana Samuel, named by the Association of South African Quantity Surveyors (ASAQS) as the most outstanding student in quantity surveying for 2012; and Sibusiso Tshabalala, one of Google’s Top 10 Young Minds.

Richard Chemaly, President of the Central Student Representative Council (CSRC), said that, by coming to Kovsies, prospective students would become the best person they can be. “We have over 70 student organisations to help you take part in student life activities. So, make use of these opportunities,” he said.

The programme concluded with an introduction to the seven faculties by the respective deans.

The estimated 7 000 prospective students and their parents also had the opportunity to visit faculties and the stalls of residences.
