Two scholars from the University of the Free State (UFS) are among 31 of the country’s leading scholars and scientists who were inaugurated as new members of the Academy of Science of South Africa (ASSAf)

Prof Johan H Meyer from the Department of Mathematics and Applied Mathematics and Prof Hussein Solomon from the Department of Political Studies and Governance were inaugurated as members of the ASSAf during the annual award ceremony that was held virtually on 14 October 2020.

Looking forward to make a contribution

Prof Solomon says he is humbled to be included into the ASSAf family.

“Earlier this year, Prof Neil Roos asked if he could nominate me for ASSAf. This was done in March, after which I heard nothing until last week. What it means to me is an acknowledgment of my cumulative academic career spanning 31 years. I look forward to making a contribution via ASSAf towards the next generation of scholars and scholarship in SA,” says Prof Solomon.

Humbled and honoured

Prof Meyer says he was asked by the top management of the UFS to apply for membership, but his inclusion came out the blue.

“I feel humbled by this inclusion – to be welcomed in a community that is regarded scientifically significant. I never expected to be selected, but I am nevertheless satisfied with the contributions I could make, in particular to the mathematical community. I feel honoured, and trust that I will be able to live up to it for several years to come,” says Prof Meyer.

Serve as role models for younger academics

Prof Corli Witthuhn, Vice-Rector: Research and Internationalisation, said this honour was bestowed upon the two researchers whose work has been judged by their peers to have significant international impact. 

 “We are very proud of the two outstanding researchers who were selected as members of the Academy of Science of South Africa during 2020. They continue to serve as role models for our younger academics in natural science and in the humanities and social sciences who are striving to produce the highest quality research that is relevant to a local and international audience.”

As the official Academy of South Africa, ASSAf honours the country’s most outstanding scholars by electing them to membership of the Academy. ASSAf members are drawn from the full spectrum of disciplines. New members are elected each year by the full membership of the Academy is in recognition of scholarly achievement. Members are the core asset of the Academy and give of their time and expertise voluntarily in the service of society. The 31 new ASSAf members bring the total membership of ASSAf to 597.

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.
