Everywhere you look, our colleagues at the UFS are stepping up and stepping into the new digital space. With the move to virtual events, staff members at the university are able to participate in discussions and webinars across the continent at various other institutions of higher learning. 

One such virtual event recently took place for Women’s Month. The Tshwane University of Technology hosted the Annual Adelaide Tambo Memorial Lecture on 27 August. The theme was Is the face of the boardroom in global organisations changing women representation in influential positions?

Dr Phumzile Mlambo-Ngcuka, United Nations Under-Secretary General and Executive Director of UN Women, focused in her presentation on themes regarding girls’ education and women’s health, both of which have been threatened by the COVID-19 pandemic.

As the respondent, Dr Maria Madiope, Principal of the UFS South Campus, dealt with the patriarchal domination and violence that modern women and girls endure, as well as the way “their sexuality and aptitude is disrespected and how they are subjugated and side-lined in the political, corporate, social, and cultural arena.” She said that it is incumbent on the modern generation of women to reignite the flame that fuelled the struggle for feminine recognition and equality. “We are beholden not only to the legacy of those that came before us, but also to the eager eyes that look up to us,” she concluded. 

Dr Madiope also announced her support for Dr Mlambo-Ngcuka’s Generation Equality campaign against gender-based violence, and she echoed the sentiments of the rallying hashtag #JustChair, which breaks down discrimination based on the use of gendered terms such as ‘chairman’ for the leader of a meeting or corporation.

Dr Adelaide Tambo’s life was characterised by a love of knowledge, as she believed that people need as much power to be able to handle challenges facing the country, the continent, and the planet. She strove for the emancipation of women in general, focusing on the importance of education and how it can improve a woman’s life, and encouraged a strong culture of learning.

The event was livestreamed on Facebook and Zoom; go to https://www.facebook.com/805899996152814/videos/1036964343420927 to watch the full presentation.

Scientists discover a water reservoir beneath the Free State
2009-12-09

The Mantle Research Group Bloemfontein (MRGB), under the leadership of Dr Holger Sommer, a senior lecturer in the Department of Geology at the University of the Free State (UFS), has discovered an enormous water reservoir 160 km beneath the Free State.

This discovery, according to Dr Sommer, is the first of its kind in South Africa after he had previously made a similar finding in Colorado, USA.

However, this water cannot be used for human consumption. “It is not frozen water; it is not molecular water; it is not fresh water; it is not salty water; it is OH – water which is sitting in the crystal lattice,” he said.

He said the reservoir was comparable in size to Lake Victoria in Tanzania.
The researchers collected eclogites from the Roberts Victor (Rovic) Mine close to the town of Boshof, south-west of the Free State, for their study.

“The Rovic eclogites are rocks which represent former oceanic crust transported into the earth’s interior by complex plate tectonic processes about 2.0 billion years ago,” explained Dr Sommer.

“These rocks were finally carried back to the earth’s surface by volcanic (kimberlite) eruptions around 130 million years ago. Eclogitic rocks are therefore a window into the Earth’s interior.”

The question from the beginning for all MRGB scientists was: Is there water inside these rocks in such depth, and if so, where is it located?

To answer this question, Dr Sommer and his research fellows separated single mineral grains from eclogite samples and prepared about 100 micrometer (0,1 mm) thick rock sections. Afterwards, specific particle accelerator (Synchrotron) measurements were carried out in the city of Karlsruhe in Germany.

“And indeed, the MRGB found water inside the studied rocks from the Roberts Victor Mine,” he said. “The water was located in defect structures in crystal lattices and along boundaries between single mineral grains.”

“The occurrence of water at such depth would give first evidence that all water of the oceans could be stored five to ten times in the earth’s mantle.”
The study was conducted about a year ago.
