Former Bok gives back to his alma mater

After a long and stellar career as a rugby player, Wian du Preez felt it would be unfair not to give something back to the game that had treated him so well.

Du Preez has been appointed as the new head coach of the Shimlas U-20 team, better known as the Kovsie Young Guns. They participate in the Varsity Young Guns competition.

Former Springbok
The 35-year-old Du Preez, a former Springbok, retired in 2016. He now works as a financial advisor at Jenwil BlueStar Financial  Advisory Services in Bloemfontein.

“Making the step from a professional rugby player to the corporate world was a difficult one. Thus, coaching provides me with the opportunity to stay involved in the game and to get out of the office.

Giving back
“I thought it would be nice to give something back after receiving so much from rugby. Having the opportunity to work with youngsters, you can help shape them for a career in rugby, should that be something they aspire to.”

Du Preez is a former Shimla himself, having worn the blue jersey between 2002 and 2004 whilst studying for his BCom (Investment Management and Banking).

Both his parents work at the university. His mother, Lizette, is semi-retired, but still acts as part-time assistant at the Department of Afrikaans and Dutch, German and French.

His father, Prof Chris du Preez, was the head of the Department of Soil, Crop and Climate Sciences and was a lecturer. In his final year before he goes on pension, he assists postgraduates with their studies.

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.
