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.

Moeletsi Mbeki discusses South Africa’s political economy

South Africa’s ongoing problems do not have their origin in the apartheid dispensation but in the British colonial period. This is according to the well known businessman and political analyst, Mr Moeletsi Mbeki, who was speaking during a guest lecture at the University of the Free State.

Mr Mbeki said the high unemployment rate among Blacks arose from the destruction of the Black small farming class in the last third of the 19th century to provide cheap labour to the developing mining sector. He said the notorious Land Act of 1913 was not the root of Black people’s loss of land but merely the legal formalisation thereof. Mr Mbeki emphasised that as long as it was argued that South Africa’s problems arose during the apartheid dispensation, problems would remain unsolved.

Regarding South Africa’s future, Mr Mbeki argued that three issues in particular were important – South Africa’s industrialisation, which ground to a halt in the 1970s, should be revived; the large scale training of industrialists with special emphasis on mathematics, science and the broader education system; and post-nationalist politics, of which parties such as Zimbabwe’s MDC, Zambia’s MMF and Mauritius’s MMM were outstanding examples.

The guest lecture was presented by the Department of Philosophy. More than 200 people attended the lecture and participated enthusiastically in the question and answer session. Afterwards, Mr Mbeki said he was impressed with the high level of the questions asked by students, which he said gave him hope for South Africa’s future.
