Female athletes dominate USSA
From left: Marné Mentz (second), Ts’epang Sello (first) and Tyler Beling (third) were in a class of their own, taking the first three spots in the 1 500m at the University Sport South Africa national championship in Sasolburg.

As expected, the Kovsie athletics team made the University Sport South Africa (USSA) national championship, held over the weekend in Sasolburg, one to remember.

Eight athletes earned gold medals, which is twice as many as last year. The total of 24 medals (including seven silver and nine bronze) is also double the number won in 2017. 

They ended third, just one gold medal below the University of Johannesburg. The female athletes won the women’s competition and contributed to seven of the eight gold medals. The Kovsies dominated the 1 500m and 5 000m events in which they both claimed the first, second and third spots. They even grabbed the fourth and sixth position in the 5 000m in which Kesa Molotsane triumphed, with Tyler Beling second, and Marné Mentz third. Mentz and Beling swapped places in the 1 500m behind Ts’epang Sello. 

Molotsane also won the 10 000m in a record time of 34:49.16 which is a massive three minutes and five seconds quicker than the previous record.

The 800m title also now belongs to Sello. She and Beling won a third medal (bronze) as members of the 4 x 400m relay women’s team. 

The other gold medalist was Lara Orrock (3 000m steeplechase), Lynique Beneke (long jump), Esli Lamley (pole vault) and Rynardt van Rensburg (800m).

All five Kovsies who competed at the CAA Southern Region Youth & Junior Championships that took place over the weekend in Boksburg, won medals. They were Pakiso Mthembu (gold, 5 000m), Michaéla Wright (gold, long jump), Tyler (gold, 1 500m), Tsebo Matsoso (silver, 200m) and Orrock (silver, 3 000m steeplechase).

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.
