Global Landmarks in the South African stratigraphic record

February, 13th
8h30 - 14h00
Council for Geoscience Boardroom, Silverton

South African geology preserves records of several of the major events in global geology. These include evidence of early life in the Barberton Supergroup, extensive Neoarchean magmatism in the Ventersdorp Supergroup, the early Proterozoic termination of a methane dominated atmosphere and the Great Oxidation event, as well as Mesoproterozoic magmatism in the Natal-Namaqua Province. The Neoproterozoic and Phanerozoic record of South Africa provides an unparalleled testament of the evolution of life on Earth as well as major catastrophes life faced in the geological past, as recorded in the rocks of the Vanrhynsdorp, Cango Caves, Cape and Karoo Supergroups. Cenozoic aged successions in South Africa have importantly played a crucial role in understanding the evolution of our own species as well as understanding the environments they lived in.

Development of new techniques continues to highlight the importance of the South African record in understanding the evolution of life on Earth and the emergence of humankind. The workshop will review these events with a view to highlighting areas where future mapping and research should be focused.

The workshop is open to all scientists active in these fields, but the venue can accommodate thirty participants so please contact Cameron Penn-Clarke ( and Christopher Hatton ( as soon as possible to confirm your attendance.

Passive treatment systems - The Good, The Bad and The Complicated

February, 13th
9h00 - 15h00

Passive mine water treatment involves harnessing natural processes for the treatment of mine water. Typically this uses naturally occurring geochemical and biogeochemical processes to treat contaminated water, in systems with flow driven by gravity. Many of the processes are similar to those which occur naturally in wetlands. During the workshop, the principles of passive treatment will be introduced, using examples from the United States and South Africa. Some of the challenges faced by passive treatment systems will also be discussed, with the objective of optimising research and implementation in the future.

The workshop is aimed at scientists and engineers active in the field and those hoping to make a contribution to the passive treatment of mine water.
