Dr Lazlo Passemiers spent six years conducting research across three continents.

A keen interest in unravelling transnational histories of 20th-century Southern Africa led Postdoctoral Research Fellow Dr Lazlo Passemiers to spend six years conducting extensive research across three continents. Dr Passemiers sifted through archives in Africa, Europe, and the US in order to convert his PhD thesis into a monograph.

It was on 17 July 2019 that the fruits of Passemiers’ labour were officially launched by the International Studies Group at the University of the Free State’s Bloemfontein Campus. His book, Decolonisation and Regional Geopolitics: South Africa and the ‘Congo Crisis’, 1960-1965, offers an important shift in the historiography of the Congo Crisis. It creatively centres African involvement in the debate by examining this event from a regional geopolitical angle. 

Going back in time 

By providing a three-fold perspective that examines decolonisation, apartheid diplomacy, and Southern African nationalist movements, the book offers a rounded picture of South African involvement in the Congo Crisis.

Dr Passemiers’ fascination with the transnational dynamics of Southern Africa’s history has rippled into two new research projects that respectively explore “the connection between decolonisation and white flight in the region as well as the transnational support networks of liberation movements”.

Finding the missing pieces of the puzzle

Prof Christopher Saunders, Emeritus Professor at the University of Cape Town, commended Dr Passemiers’ historiographical contribution: “He has identified a major gap in the literature and he has filled it admirably by looking across the spectrum.” As Prof Saunders noted, “what has been missing in the literature is the African angle.” 

Literature’s role in transformation

The process of undoing the profound impact of colonialism on society is long and difficult and important in this process is a clear understanding of history, which Dr Passemiers’ book enhances.

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.
