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.

School of Medicine expands to provide quality tuition
2015-04-20

 

The School of Medicine at the University of the Free State (UFS) has recently extended various training platforms to provide continuous quality tuition to students.

Not only does the school boast a world-class dissection hall but now has plans for additional training facilities at two more hospitals.

The new dissection hall was completed in January 2015 with some final finishing touches that will be done shortly. The hall is newly built as the previous dissection hall has been used for undergraduate anatomy training since 1972.

Dr Sanet van Zyl, Senior Lecturer in the Department of Basic Medical Science, says owing to a prospective growth in the number of medical students as well as changing methods in teaching and learning, the need for a new dissection hall became evident to ensure that students get an optimal learning experience during dissection tuition.

“The new spacious dissection hall is equipped with special lighting and modern equipment for the training programme for second-year medical students. The hall is further equipped with modern sound and computer equipment. A unique camera system will allow students to follow dissection demonstrations on ten screens in the hall. Dissection demonstrations can also be recorded, enabling lecturers to put together new materials for teaching and learning.”

In addition to anatomy teaching for under- and postgraduate medical students, the Department of Basic Medical Science also offers anatomy teaching to under-graduate students from the School of Nursing, the School of Allied Health Professions as well as students from the Natural and Agricultural Sciences (such as students studying Forensic Science). The old dissection hall will still be used for the anatomy training of these students.

“The dissection programme for medical students is of critical importance, not only to acquire anatomical knowledge, but also for the development of critical skills and professionalism of our students. As already mentioned, these modern facilities will enable us to be at the forefront of current development in this field. This will benefit both present and future generations of medical students.”

At the same time, Prof Alan St. Clair Gibson, Head of the School of Medicine, announced that lecturing facilities are being developed at the Kimberley Hospital Complex. There are also plans for study facilities at the UFS’s Qwaqwa Campus and Bongani Hospital in Welkom. The UFS’s planning is also well underway for lecturing and residential facilities for students in Trompsburg, where students will receive training at the Trompsburg Hospital.

“We are very privileged to have these facilities and they will help us to provide world class training for students in the School of Medicine,” Prof St. Clair Gibson says.
