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.

First-year students encouraged to attend UFS welcoming function
2006-01-12

The University of the Free State (UFS) will host a welcoming function for all new first-year students and their parents on Saturday 14 January 2006 in the Callie Human Centre on the Main Campus in Bloemfontein.

The function starts at 11:00 and will be addressed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie. UFS staff will also be available to provide vital information to first-year students on academic matters.

According to Mr Vernon Collett, Registrar: Academic Student Services at the UFS, Saturday’s welcoming function can assist students and parents by providing vital information on the many high quality academic learning programmes on offer at the UFS in six faculties.

“If students and parents have this information it will make the registration process, which starts next week Tuesday 17 January 2006, much smoother,” Mr Collett said.

The UFS has split the registration process into various categories of students and Mr Collett appealed to all students to adhere to the dates and times which apply to them as a one-stop service will be available so as to avoid unnecessary delays in the registration process.

The registration of first-time entering first-year students who applied before 30 November 2005 to study at the Bloemfontein Campus will take place from Tuesday 17 January 2006 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 23 January 2006.

Postgraduate students, first-time entering first-year students and other students who applied for admission to the main campus after 30 November 2005 must register at the Callie Human from 2 February 2006. 

Late applications will be accepted until Wednesday 25 January 2006 at the Information Centre on the Main Campus’ Thakaneng Bridge. These applications will be regarded as pending and will be processed as places become available on the programme the student has applied for,” said Mr Collett. 

Vista Campus:
The Vista Campus in Bloemfontein – which was incorporated into the UFS in January 2004 – no longer accepts applications from first-year students. Such prospective students had to apply to the UFS Main Campus. Students who had been registered on the Vista campus last year must register at the Vista Campus on the same dates as applicable on the Main Campus.

Qwaqwa Campus:
At the Qwaqwa Campus of the UFS, all first-time entering first-year students must report on Thursday 19 January 2006, after which the registration of these students will take place according to a specific programme. The official welcoming functioning for new first-years at the Qwaqwa campus of the UFS will take place on Saturday 11 February 2006 at 08:00 in the Rolihlahla Mandela Hall on the Qwaqwa Campus.

Mr Collett appealed to first-year students who have applied to study at the Qwaqwa Campus and their parents to attend this function which fulfils the same role as the one held on the Bloemfontein Main Campus.

Detailed information on the dates and times of registration for the various faculties and academic learning programmes is available on the UFS website at www.uovs.ac.za. Prospective students may also call the Main Campus in Bloemfontein on (051) 401-3000 or the Qwaqwa Campus on (058) 718-5000 for more information.
