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 hosts first ACS Institute held on African soil
2015-12-08



The first ever Association for Cultural Studies (ACS) Institute hosted on the African continent is taking place on the Bloemfontein Campus. At the event are, from the left: Prof Jonathan Jansen, Vice-Chancellor and Rector of the UFS; Prof Jean Comaroff, Alfred North Whitehead Professor of African and African-American Studies and Anthropology at Harvard University; Prof Helene Strauss, Chair of the Department of English at the UFS; and Prof Gil Rodman, Chair of the Association for Cultural Studies and Professor of Communication Studies at the University of Minnesota.

The University of the Free State (UFS) is hosting the 2015 conference of the Association for Cultural Studies (ACS) Institute – the first time for this international event to take place on the African continent.

From 7 – 12 December 2015, some of the world’s leading scholars in cultural studies are taking part in the conference on the Bloemfontein Campus. The event has been organised by the UFS Department of English in collaboration with colleagues from other departments in the Faculty of the Humanities.

 The ACS is the foremost international association for scholars in cultural studies, and has been hosting the biennial Crossroads in Cultural Studies Conference since 2006. In 2011, the ACS held its inaugural institute at the University of Ghent (Belgium), followed, in 2013, by one at the Alpen-Adria University Klagenfurt (Austria). As the 2015 meeting of the institute is the first to be held in Africa, the organisers aim at highlighting the contributions that scholars from our continent and other (post)colonial contexts have made to cultural studies, even as it engaged many of the long-standing theoretical concerns generated for the field by scholars from the Global North.

Themed ‘Precarious Futures’, the conference explores how cultural studies might assist in charting more equitable futures by reflecting critically on the cultural, economic, and political trajectories within which precariousness – a state increasingly anticipated for the planet – might be altered. Experts in a diversity of disciplines are sharing their perspectives in the form of seminars and lectures.

Keynote lectures are delivered by Prof Jean Comaroff (Harvard University), Prof John Erni (Hong Kong Baptist University), Dr Jo Littler (City University London), Dr Zethu Matebeni (University of Cape Town), and Prof Handel Kashope Wright (University of British Columbia).

In her opening lecture on Monday 7 December 2015, Prof Comaroff addressed the challenging relationship of law, detection, and sovereignty in contemporary African polities within the South African post-apartheid context.

Topics discussed include climate change; the archives of everyday life; cross-racial intimacies; ethnography; meritocracy; cultural studies and human rights; China and globalisation; gender, sexuality, and race; and governance, embodiment and the work of care.
