Gateway 2019

The two-week Gateway Orientation programme to introduce first-year students to campus and faculty life on the Qwaqwa Campus,  has been a resounding success – if the first-years’ comments are anything to go by.

“Amazing Race was for me the pinnacle of this programme, as it enabled me to get to know the campus much better. It was such a refreshing experience, despite my sore thighs that are still hurting. I also loved the Step Up for success initiative,” said Chulumanco Mazwi from Mthatha in the Eastern Cape. Chulumanco has enrolled for a BAdmin degree, which will “enable me to interact with people, particularly in the corporate world”.

From Paballong Village in Qwaqwa came a budding scientist, Mookgo Mofokeng. “The programme has afforded me the opportunity to interact with a number of students from different places such as KwaZulu-Natal, Eastern Cape, and Gauteng,” she said. “I have also learnt about the history of the campus that is very close to my heart,” said Mookgo. “This is the campus where I won the prize for my Eskom Expo for Young Scientists project, with my partner and I displaying our water-extracting project as learners from the Beacon Secondary School here in Qwaqwa. For more on this, please watch the environmental television programme 50/50 on SABC 2 on 17 February 2019.”

Coming from Newcastle in KwaZulu-Natal is ‘the future businessman in the computing sector’, Lethukuthula Nsibande. “The Gateway orientation programme was so much fun, as it enabled me to see teamwork as an integral part of our development as first-years. Considering that I want to pursue business in the interesting world of computers, I have seen that interacting with others is crucial,” said Lethukuthula, a BSc IT (Computer Science and Management) student.

From Johannesburg, Gauteng, comes Siyalungelwa Ntombela, a BEd (Intermediate Phase – Life Sills and Social Sciences) student who believes her studies will enable her to give back to her community. “I want to educate our future generations and make a difference. I found Gateway to be educational and entertaining. We have learnt a lot about university life and the campus in general. I now know about the services offered by the clinic, where the Mandela Hall is, and so on. Interacting and learning from our mentors was also one of the highlights,” she added.

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.
