Lerato Mbongo and Opheleleyo
Double belted! Opheleleyo Qwabe and Lerato Mbongo revel in the moment.

Their friendship began in high school, where they were constantly told by teachers that they would not make it to university, but these best friends never gave up. On Thursday 21 April 2022, they received their honours degrees in the Faculty of Natural and Agricultural Sciences together during the afternoon ceremony of the University of the Free State’s April Graduations.

Lerato Mbongo and Opheleleyo Qwabe, who have been friends since Grade 9, said being picked on in class for not being the brightest learners brought them together and motivated them to work harder.Mbongo obtained a Bachelor of Agriculture Honours majoring in Wildlife Management, and Qwabe received a Bachelor of Agriculture Honours majoring in Agricultural Economics.

“We’ve always dreamed big, but if you had told us back then that we would one day be two-time graduates, we wouldn’t have believed it. During one of our Maths lessons back in Grade 9, our teacher went around asking the ‘smarter’ kids what they wanted to study after matric, but when he got to us, he said there was no point in asking because we wouldn’t make it that far anyway,” Qwabe said.

The friends, who both started at the university’s South Campus, said they were grateful for the UFS Preparation Programme, as it boosted both their marks and their confidence. “The programme helped us to believe in ourselves again, and also played a big role in helping us discover what we wanted to study. The courses we enrolled in really unlocked an unstoppable passion in us and helped us realise that nothing is impossible. Today, here we are celebrating 10 years of friendship, and our honours degrees. We’ve conquered once again, and we're sharing our victories together,” Mbongo said.

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.
