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.

UFS law students sit in on exceptional case in the Supreme Court of Appeal
2011-09-21

 
At the Supreme Court of Appeal were, from left to right: Dr Beatri Kruger, lecturer in our Department of Criminal and Medical Law at the Faculty of Law; Adv. Ann Skelton, Amicus Curiae instructed by the Restorative Justice Centre; Ms Matsepo Soko, post-graduate student in Criminal Law; and Prof. Annette van der Merwe from the University of Pretoria.

Fourth-year and master’s-degree students, from our Faculty of Law, had the privilege of attending the hearing of one of their prescribed cases in the module, Criminal Law, namely the State versus Tabethe, in the Supreme Court of Appeal. Apart from the fact that they could attend the hearing, the students were also addressed by experienced legal experts, Adv. Ann Skelton (amicus curiae, instructed by the Restorative Justice Centre) and Prof. Annette van der Merwe from the University of Pretoria, on the broad outlines of the case.

In this case, the accused was found guilty of raping his fifteen-year-old stepdaughter. The court imposed a sentence of ten years’ imprisonment, suspended in full, but with certain conditions. The conditions include 800 hours’ community service and stipulate that the accused has to follow a rehabilitation programme and that he has to give 80% of his income to the family in order to support the victim and her family.
 
This was the first rape case where, in following a restorative justice approach, exceptional conditions were imposed to address the interests of the victim who wants to proceed with her studies. The State appealed against the sentence.
 
Dr Beatri Kruger, lecturer in our Department of Criminal and Medical Law, who prescribed this case for the students, said, ‘The law students were indeed privileged to attend this auspicious and enriching occasion, which provided them with an insightful experience of how the law works in practice.’
