Rynardt and Lynique selected for SA team at World Cup
Long jumper Lynique Beneke is one of two Kovsies selected for the South African team to the inaugural Athletics World Cup.

University of the Free State (UFS) middle-distance runner, Rynardt van Rensburg, and long jumper, Lynique Beneke, have both secured a spot in the South African athletics team for the inaugural edition of the Athletics World Cup to be held in London, United Kingdom, on 14 and 15 July 2018. 

The 2018 domestic rankings were used to select the team, with one UFS athlete in each discipline set to represent the country as one of the eight competing nations at the event. Beneke, aged 27, won the long jump for women over the past two years at the national track and field championships, this year with a winning distance of 6,22 m. Van Rensburg, aged 26, won silver.

South Africa will compete against teams from the United States, Poland, China, Germany, France, Jamaica, Great Britain, and Northern Ireland. Beneke and Van Rensburg are both experienced athletes who have competed in the Olympic Games in 2016. The programme for the two-day championship does not include long-distance or combined event disciplines. Yolandi Stander, Van Rensburg, and Beneke have also been selected as part of the preliminary team for the CAA African Championships taking place in Asaba, Nigeria from 1 to 5 August 2018.

Van Rensburg recently clocked his personal best, which was also recorded as the 24th best time of the year, when he finished the Hengelo World Challenge meeting in 1:45.15.
Stander, who has a personal best of 52,81 m, won the bronze medal at this year’s nationals and a silver at the University Sports South Africa (USSA) meeting.

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.
