Economic geological analyses of the future availability of mineral resources

Production cycles of non‐renewable georesources are being modeled – both into the future and the past - and the total mineable amount of a given georesource and the prediction of future availability of such resources are being approximated on a regional and global scale. This research is aimed at aiding decision makers with regard to formulating policies on securing the future supply of critical georesources.
Models refer to both likely future production cycles as well as historic production.
Concrete examples include golduranium, copper, crude oil, and mercury.


Genesis of gold deposits

Several projects on the genesis of the world’s largest accumulation of gold in the Mesoarchaean Witwatersrand Basin in South Africa and similar Witwatersrand-type deposits elsewhere (Brazil, Canada, India, Australia).

In spite of the enormous economic significance of the Witwatersrand gold, its genesis has remained for more than a century "the most disputed issue in the history of economic geology". Our results made a significant contribution to the on-going debate on the origin of the Witwatersrand gold. Although in its present form most of the gold appears late in the paragenetic sequence and thus to be the product of hydrothermal precipitation, overwhelming evidence exists for an autochthonous, detrital source of the gold within the conglomeratic metasedimentary host rocks. Thus a modified palaeoplacer model is preferred to explain the available data/observations on this real giant amongst gold districts.

In a follow-up study, the source of the huge amounts of detrital gold particles in the Witwatersrand Basin is being evaluated. To this effect the pre-Witwatersrand basement rocks are being studied. First results point to a sulphidic IOCG-style low-grade gold enrichment in some of these rocks, formed during a major gold event at about 3 billion years, when the dominant crust-forming regime changed from a plume-driven to plate-tectonically driven Earth.

In a further project, the distribution of gold in the Earth’s crust has been evaluated with the aim of pinpointing the first-order controls on the concentration of gold into ore bodies within the continental crust.


Sediment-hosted base metal deposits

Study of the genesis, fluid characteristics and tectonic as well as palaeoclimatic setting of a variety of sediment hosted Cu-, Pb-, and/or Zn-sulphide deposits. Examples include the following ore districts: Otavi Mountainland, northern Namibia, Rosh Pinah, southern Namibia, and Bushmanland, northern Namaqualand, South Africa


Geodynamic evolution of southwestern Gondwana

Correlation of Pan-African orogenic belts in southwestern and central Africa with their counterparts in South America gives insights into the birth of a supercontinent (Gondwana) and the relationship between tectonics, palaeoclimate, ocean water chemistry, evolution of life and metallogeny. Special emphasis has been on the Gariep and Saldania Belts in southern Africa and the Congo Belt in central Africa. This work forms part of two International Geoscience Programmes (IGCP 478 and 512) and the DFG-supported priority programme onSouth Atlantic Margin Processes and Links with Onshore Evolution (SAMPLE).


Precambrian palaeoclimate

Using sedimentary geochemistry and style of mineralization as proxies, the evolution of the atmosphere and hydrosphere are being reconstructed. Special focus of this research is on the Archaean, the time before the big oxygenation of the atmosphere, and on the Neoproterozoic to Early Cambrian, when our planet experienced some extreme climate changes. Study targets include Archaean sedimentary successions, such as those in the Witwatersrand Basin, Palaeoproterozoic sedimentary successions in Guyana, Neoproterozoic sequences in the former West-Gondwana, and black shale deposits on the Yangtze Platform in South China.


High-grade metamorphic terranes in Antarctica

Meso- to Neoproterozoic tectonic belts exposed in isolated nunataks on the periphery of the huge East Antarctic ice mass play a pivotal role in the palaeogeographic reconstruction of an inferred supercontinent that existed prior to Gondwana, commonly referred to as Rodinia or Palaeopangaea. As part of the South African National Antarctic Programme, we studied the tectono-thermal evolution recorded by one of these belts, which is closest to Africa, i.e. the Maud Belt in Western and Central Dronning Maud Land.

Similar studies have been conducted as part of the DFG-supported priority programme on Antarctic research on rocks from the Shackleton Range. The results revealed the presence of three distinct terranes that became juxtaposed during multi-stage Pan-African tectonothermal events in the course of Gondwana amalgamation. Our single zircon data also gave new insights into the behavior of Hf isotopes in zircon during metamorphism.

More recently, this work has been extended to southern India, where in a DFG-supported project, in cooperation with Indian partners, ultrahigh-temperature metamorphic rocks are being studied both in the "Grenvillian" Eastern Ghats Belt and the "Pan-African" Madurai Block.
