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.

Publication on indigenous knowledge systems

UFS launches most comprehensive publication on indigenous knowledge systems
A unique collection of essays on Indigenous Knowledge Systems (IKS) was launched yesterday (20 October 2005) by the University of the Free State’s (UFS) Programme of Africa Studies.

The essays are published as a special edition of INDILINGA, the African Journal for Indigenous Knowledge Systems and is an outcome of the colloquium on Indigenous Knowledge Systems that was presented last year by the UFS Director of Africa Studies in cooperation with the National Research Council.

“The amount and diversity of materials on IKS brought together under one cover is unique as there are no other South African publications of this magnitude on this issue.  It contains papers of international experts on IKS such as Prof Fritz Wallner from Austria and Prof Gayatri Spivak, foremost postcolonial theorist from India,” said Prof Philip Nel, Director of Africa Studies and guest editor of the publication.

“The publication is a rich source field for students and scholars to exploit because most of the sources quoted in the articles are recent, fresh and relevant.  The contributors are largely people responsible for managing, fostering and studying IKS in a responsible manner,” said Prof Nel.

“An added value of the publication is the inclusion of the policy document on IKS that was adopted by Cabinet in November 2004,” said Prof Nel.


“Millions of people in South Africa are faced with the painful choice of abandoning their heritage.  In this choice, the study and management of IKS has a major role to play; on the one hand, to encourage as much assimilation of traditional knowledge as possible into the modern systems, and on the other hand to provide a “language” and a “grammar” for indigenous people through which they can access modernity,” said Prof Nel.

The IKS debate involves questions of African identity, protection of indigenous communities and practices, political aspects as well as the scientific integrity of the enterprise. 

The publication displays the range of burning questions that have to be resolved in this field such as mainstreaming IKS in academic debate and practice, recognition and protection of the knowledge holders, bio-prospecting and bio-piracy, bio and ethnic healing, lack of textbooks and field manuals, etc and will prove worthwhile for future researchers.

 “One of the main reasons for publishing this volume is the fact that IKS should be studied not only to provide a sense of pride in the past, or  to engender respect for indigenous peoples, but also to enable people in indigenous mind sets to make a better transition into the world of science and technology,” said Prof Nel.

The guest speaker at the launch was Dr Otsile Ntsoane, acting Director of IKS at the Department of Science and Technology.  In his speech Dr Ntsoane stressed the symbolic and concrete value of the publication.  “The publication can have a great social impact and the research results can contribute to chancing the economic landscape of South Africa,” he said.

The publication can be purchased at R150 per copy.  For more information, Ms Steffi Cawood, Programme Coordinator for Africa Studies at the UFS can be contacted at (051) 401-2614.
