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.

But do you forgive yourself, Eugene de Kock? asks Candice Mama

Candice Mama and her family met with her father’s assassin. Eugene de Kock. Prime Evil. Commander of the apartheid government’s covert Vlakplaas police unit. And what followed from this meeting was one of our country’s most poignant gestures of reconciliation. One by one, each family member expressed their forgiveness of De Kock, and soon afterwards, he was granted parole.

Candice recently visited the Bloemfontein Campus to talk about ‘An Unexpected Encounter with Eugene de Kock: A Journey of Transformation’. The event was a collaborative effort between the Institute for Reconciliation and Social Justice and Trauma, Forgiveness, and Reconciliation Studies.

“What makes it possible to cross the boundary from loss and pain to bond with the person who hurt you?” Prof Pumla Gobodo-Madikizela, asked Candice. “I had to educate myself about the when, where, and how, to get a context for Eugene de Kock,” she answered. With the encouragement of her mother, Candice became an avid reader from an early age. She devoured information, so that she could build a picture of this man within a specific historical and political context. What also contributed to this moment of reconciliation for her was De Kock humbling himself and taking full responsibility for his actions.

This meeting was not without inner conflict for Candice, though. “Why am I crying for hím?” she asked herself as she listened to him speak. “Why am I laughing?” she chastised herself as De Kock preened shyly for a group photograph with the family. “Is there something wrong with me to connect with him?” She questioned her values and beliefs. But instead of a monster, Candice saw the true essence of a repentant human being.

But how do you know he didn’t fake it, many people asked. Because it was “one of the most sincere and honest encounters I’ve experienced,” she said. During their meeting, Candice saw a man “crushed by the world”. Everything he believed as a young man, he realised, was a lie.

“Do you forgive yourself?” Candice asked the one question De Kock feared most. And in that moment, he was humanised for her. “When you’ve done the things I’ve done,” De Kock replied, “how do you forgive yourself?”
It remains an open question. But this act of forgiveness gives an entire country hope.
