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.

Prestigious Helgaard Steyn Prize to be awarded to UFS composer
2010-11-08

 Hans Huyssen.

The composer Hans Huyssen, affiliated with the Department of Music at the University of the Free State (UFS), is to be the current recipient of the prestigious 2010 Helgaard Steyn Prize, the prize-winning work being Huyssen’s Proteus Variations (2006).Annually this award is administered and presented to a selected composer, painter, author, or sculptor by the Universities of the Free State and the North-West on a rotating basis. The judges for this year’s prize were Prof. Bertha Spies, Research Fellow, North-West University, and Professor Extraordinary, University of Pretoria, and Mr Noel Stockton, Senior Lecturer at the University of the Free State.

Hans Huyssen’s musical activities encompass the diverse poles of early and contemporary Western and African music, often in an attempt to assimilate the essential qualities from all these fields. His intense focus on contextuality suggests that he approaches music as a profoundly social force which has a particular role to play in our ‘new’ diversified South African society.

The Proteus Variations were commissioned by the Deutsche Welle Radio for the South African National Youth Orchestra 2006, and were premiered at the Beethoven Bonn Festival during 2006. These variations are described by the composer as “a musical representation of South Africa’s manifold Proteaceae”, named for the Greek god Proteus who, at will, was capable of assuming a spectrum of shapes and appearances. As the composer states: “It is worth noticing that a Protea is South Africa’s national flower. What could be more appropriate in providing a key to an opposite perception and understanding of the country’s diverse cultural expressions? In this regard it is my hope that the Proteus Variations may contribute a little to the wide scope of cultural responses necessary to begin to do justice to the extremely rich tapestry of our immediate cultural and natural surroundings”.

The prize of R170 000 will be awarded to Hans Huyssen by a representative of ABSA Trust, who is one of the trustees of the Helgaard Steyn Trust, in Bloemfontein on 8 November 2010.
