Antonet Louw, star hockey player, was the leading goal scorer at the University Sport South Africa championship in Stellenbosch. She achieved the same milestone in the Varsity hockey competition in May.

Improvement by the Shimlas, men’s hockey, volleyball (men and women), and basketball teams (men and women), and stumbling over the final two hurdles by the netball and women’s hockey teams.

This, in a nutshell, was the Kovsie story at this year’s University Sport South Africa (USSA) championships that took place across the country in the first week of July.

The Shimlas improved from fourth to third place in 2019, winning two of their three encounters. The hockey men, who finished second in last year’s B Section, were unbeaten in 2019, earning them an automatic promotion to the A Section in 2020.

The men’s volleyball team improved from 11th to 6th place, the women from 15th to 5th, and the basketball men (6th) and women (9th) improved by three and one positions respectively.

For a large part of the netball and women’s hockey tournaments, it looked very promising that one or both of the UFS teams could go all the way.

The netball team has won all five of their group matches, including victories over the North-West University (NWU) and Tuks, against whom they lost in the play-off fixtures on the final two days.

Another milestone by Antonet
This was also the case with the women’s hockey team. They recorded wins in all three of their group matches, including a 3-0 win over the Maties, who were the Varsity hockey runners-up in May. In the semi-final, Tuks prevailed by 4-0 and in the play-off for third/fourth place, the Maties triumphed by 3-1.

Antonet Louw, the leading goal scorer during the Varsity hockey tournament, again contributed the most goals (five in five matches).

In the fencing championship, Relebohile Pule (women’s epee) and Johanco Viljoen (men’s sabre) both returned with bronze medals.

Ewald van Zyl (elite male kumite +84 kg, gold medal) and Diena Benade (elite female kumite -68 kg, gold) were the two standouts in karate.

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.
