UFS Debate Society
The UFS Debate Society led by example at the 2019 Jozi Rumble.
After competing in the Jozi Rumble final for six consecutive years, the UFS Debate Society won the competition – Africa’s largest intercollegiate debate open – for the second consecutive year. The tournament took place at the University of the Witwatersrand (Wits) in April 2019.

After seven preliminary rounds, three UFS teams out of a total of 100 competing teams overall were placed in the top 16, earning them a place in the quarterfinals – where they faced each other. A composite team of UFS LLB graduate and LLM student, Lehakoe Masedi, and a partner from Wits beat all teams, qualified for the final themed ‘This house regrets the glorification of opulence in popular culture’, and won the league.

“It was one of the most validating moments of my entire debating career; everybody wants to win the Jozi Rumble, and to have done it and to be the best speaker is truly amazing,” said Lehakoe. The top-ranking speaker at the tournament added that she had been working hard, and that she is glad that her efforts are coming full circle.

The UFS sent six teams overall to the tournament, including two novice teams competing in their first-ever intercollegiate debate tournament. 

“Speaking at the Jozi Rumble debate tournament for the first time was truly an educational experience; it exposed me to the dynamics of varsity-level debating,” said Simphiwe Yana, debater in of the UFS novice teams.

The UFS speaking squad consisted of Lehakoe Masedi, 2018 Abe Bailey Bursary victor and Rhodes scholarship recipient Nkahiseng Ralepeli, Khotso Khokho, Siyanda Rixana, Morena Moabi, Simphiwe Yana, Luvuyo Shoco, Asemahle Noholoza, and Nontobeko Msimangu. Former Chairperson of the UFS Debate Society and Editor-in-Chief of the IRAWA newspaper, Tshiamo Malatji, was also present at the tournament as the Tabulation Director. 

On 11 May 2019, the UFS will travel to the University of Pretoria to defend yet another debate open title at the Pretoria Parlay Intervarsity.

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

Dr Holger Sommer

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.
