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.

Is Al-Qaeda operating in South Africa?
2014-09-29

 
Our Department of Political Studies and Governance recently hosted a seminar with investigative journalist De Wet Potgieter – author of the book, ‘Black Widow White Widow’.During the seminar, Potgieter reflected on the research he has conducted for the book, revealing the unsettling presence of Al-Qaeda in South Africa.

The ‘White Widow’ in the book’s title refers to Samantha Lewthwaite, a British woman who was found in South Africa with a fraudulent passport. She was later linked to the Westgate shopping mall attack which took place in Nairobi, Kenya on 21 September 2013. In this mass shooting at least 67 people died and over 175 people were wounded. The Islamist group al-Shabaab – which is also linked to Al-Qaeda – claimed responsibility for the incident.

In contrast, the ‘Black Widow’ is the disclosed identity of an Afrikaans-speaking self-styled spy, who after being widowed became a counter-terrorist operative.

Potgieter’s book divulges details of Al-Qaeda paramilitary and urban warfare training on a secluded farm in the Little Karoo and reveals details of the support they receive from various local extremist groups. Potgieter’s investigation spans across two years and suggests possible future attacks from, or on, South African soil.

“South Africa plays a role in the bigger picture for Al-Qaeda Islamic terrorism,” Potgieter said. “For instance, the Navy Seal team who killed Bin Laden found reports pointing to active Al-Qaeda/Islamist presence in South Africa. South Africans need to know we are under siege by a small, well-trained Al Qaeda terrorist cell. Yet, operations – of which I know, but cannot disclose much – are also underway to contain these matters,” Potgieter added.

Potgieter’s sources suggest that Al-Qaeda has been active in South Africa since the 2010 FIFA World Cup already. The South African government seems to turn a blind eye, though, despite CIA and MI6 requests and enquiries on the matter.
