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 offers bursaries for interpreters
2005-12-01

The Unit for Language Management (previously Unit for Language Facilitation and Empowerment) at the University of the Free State (UFS) is offering bursaries to persons who want to apply for the Post-graduate Diploma in Language Practice (interpreting) for 2006. 

The Unit was involved in the setting up of a comprehensive interpreting infrastructure at the Free State Legislature and provided the interpreting services for the Truth and Reconciliation Commission (TRC) for the latter’s full duration.

“The UFS supports a multilingual society.  Our language policy, which was approved by the Council in 2003, is a striking example.  This policy is in accordance with the national movement towards multilingualism and the recognition of language rights.  Through the training of interpreters the UFS is empowering others to exercise their language rights and to partake meaningfully in formal conversations,“ said Prof Theo du Plessis, head of the UFS Unit for Language Management (ULM). 

“The UFS has been using interpreter services at executive management meetings and other occasions such as meetings, seminars and conferences for several years.  The demand for these services has risen quite considerably.  We have found that the current three interpreters on the Main Campus will soon not be able to cope with this demand,” said Prof du Plessis.

According to Prof du Plessis institutions like the Mangaung Local Municipality and the Motheo District Municipality use the interpreter services of the ULM on a regular basis. 
“Because the demand for interpreter services is becoming so great, the demand for trained interpreters is also increasing.  This is why we are offering bursaries for persons who want to be trained as interpreters to register in 2006 for the Post-graduate Diploma in Language Practice (interpreting) as offered by the UFS Department of Afro-asiatic Studies and Language Practice and Sign Language,” said Prof du Plessis.

According to Prof du Plessis the UFS will be able to use these students on an ad-hoc basis to assist with interpreter services on the Main Campus or to deliver interpreter services to institutions outside the UFS. 

The bursaries will preferably be awarded to persons with English as mother tongue with an above average knowledge of Afrikaans or Sesotho.  The duration of the bursaries is one year and only tuition fees will be paid.  “To qualify for the bursaries, prospective students must have an undergraduate qualification,” said Prof du Plessis.

The closing date for applications is 25 January 2006.  For any enquiries, Mrs Susan Lombaard can be contacted at (051) 401-2405 or 072 605 4966 during office hours or at lombasc.hum@mail.uovs.ac.za.
