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.

State of our campuses: UFS extends vacation as from 28 September until 7 October 2016
2016-09-28

In solidarity with the call for free education for the poor and missing middle, a discussion was held with the University Management Committee this morning, in consultation with the student leadership, and after careful assessment of operational matters on all three campuses of the University of the Free State (UFS), we agreed upon the following:
 
1.    All classes, tests, and assignments will be suspended until Friday 7 October 2016. This means that the university will close on Wednesday 28 September 2016 for an extended vacation until 7 October 2016. The academic programme will resume on Monday 10 October 2016.
                     
2.    This will allow the entire university time to demonstrate solidarity, in collaboration with student leadership, academic and support staff, and the broader community in support of free higher education for the poor and missing middle.
                  
3.    The administration of the university will continue on Thursday 29
September 2016, and staff will have access to their offices to plan the additional academic support for students, to consider the re-scheduling of the academic calendar, to engage with the Department of Higher Education and Training in relation to the students’ demands, and to continue with support services during the extended vacation.
 
4.    The university management and student leadership will also, over the next three days, engage in discussions to provide for a platform that is conducive to continued collaboration between students and the university leadership.
 
5.    The suspension of tests, classes, and assignments will also allow time for a social compact and code of ethics for protests to be agreed upon and signed between student leadership and the university management.

 In respect of the Qwaqwa Campus, some protesting students yesterday intimidated others and forcibly removed staff, as well as security personnel. Today, university property was burnt. In view of our commitment to the safety of staff, students, and university property at the campus, it was necessary to evacuate the campus – including residences – with immediate effect. However, residential students are allowed to remain on campus until midday tomorrow (28 September 2016).

The university leadership again wants to emphasise its support for a national policy of free education for the poor and missing middle and stresses its support for peaceful protests on matters that are of concern to our students.
 
We further understand the frustration of many students and their parents/guardians at the closure of the campuses and the impact it has on academic staff, staff in the Support Services, our security personnel, teaching, learning, projects, assignments, lectures, tests, fieldwork, and the academic calendar in general, and commit to do all in our power to ensure the delivery of quality education to all our students under difficult circumstances.
