WS2. Platreef workshop Further details on this workshop can be obtained by directly contacting the leader of the workshop
Prof J. Kinnaird (Wits)

WS3. Analytical Techniques and South African Analytical Facilities:
This workshop is aimed at highlighting and explaining important analytical techniques as well as the presentation of state of the art analytical facilities in SA. As part of this workshop 2 integrated analytical facilities will be visited.

WS4. Earth Science Education in Africa: A UNESCO Initiative
About the workshop: Review of UNESCO’s African Earth Science Education Initiative during which action plan for the Initiative will be presented and will be finalized during the October Paris Event. This workshop will give participants an opportunity to discuss opportunities that are already arising as a result of this initiative, including major efforts to build international geoscience networks for students, researchers, and teachers. There will also be an opportunity to review the work done in the Initiative and to make recommendations for future progress.

WS6A. GIRAF Workshop: (combined with AEGOS and One-Geology)

GIRAF is an initiative to stimulate the adoption of appropriate information and communication technology (ICT) in the geological surveys of Africa and to help build the pan-African geoscience knowledge network. We held our inaugural meeting in Windhoek in March 2009 and attracted almost 100 geoscientists from 30 countries (26 of them African countries) and heard reports of the varying degrees of development of ICT capacity across Africa. A second meeting is planned for Tanzania later in 2011. The workshop at CAG23 is designed to raise awareness of GIRAF amongst the broader geosciences community in Africa and to collect input and ideas that could support the project’s goals. The GIRAF executive will review the scale of the task ahead based on national reports from the Windhoek meeting and highlight successes (and failures?) since then in mobilising the necessary resources and the self-help network.IMG_6220 IMG_6270

WS6B. AEGOS (BRGM): (combined with GIRAF and One-Geology)
further information can be obtained by contacting
Dr. M. Urvois

WS6C. OneGeology: (combined with GIRAF and AEGOS)
further information can be obtained by contacting
Dr. I. Jackson
OneGeology is a global initiative of the geological surveys of the world. Its aims are to make geological map data accessible via the internet to all; exchange the know-how to enable all nations to contribute; and to improve interoperability using the web language GeoSciML. The OneGeology session will include an update on progress, how organisations can participate and register, how to use the portal, and technical information on how to provide your data to the OneGeology portal.

About CAG23

“Together in Africa for a Leading Role in Geosciences”
The “Colloquium of African Geology” (CAG) is a major biennial meeting organized under the auspices of the Geological Society of Africa (GSAf). This event, which can attract up to several hundred delegates worldwide, provides ample opportunities to present advances and unsolved problems in geoscience topics related to Africa on a continental-scale. Since inception of the colloquium in 1965, it has been hosted by several European countries (17 times) and only a few times (5 times) by African countries (Swaziland, Zimbabwe, Morocco, Mozambique and Tunisia). Considering the fascinating and the unique geological features of Africa, we believe that it is necessary to host this prestigious event as many times as possible on the African continent and bring geologists to the “home of geology”. Based on this, South Africa presented a bid during the 22nd Colloquium of African Geology (CAG22) and the 13th Conference of the Geological Society of Africa held in Hammamet, Tunisia, on the 6th of November 2008. The General Assembly of the Geological Society of Africa has agreed to allocate unanimously the CAG23 to South Africa.

fig168The CAG23 will be organized by the University of Johannesburg in cooperation with the University of the Witwatersrand, the Geological Society of South Africa (GSSA), the Mineralogical Association of South Africa (MINSA, a division of the GSSA) and the Nuclear Energy Corporation of South Africa (NECSA) under the auspices of the Geological Society of Africa (GSAf):

Call for Papers

Nature has gifted Africa as a foremost continent in terms of its mineral and natural resources. However, it is our responsibility to ensure that the Geosciences in Africa will continue to play a part commensurate with this position, hence the Colloquium theme “Together in Africa for a leading role in Geosciences”. By understanding the geological history and geodynamic evolution of the African continent, we will contribute towards a better and deeper insight into the nature and occurrence of a wide range of natural resources (groundwater, energy resources, mineral resources, etc) that are essential not only to mankind but also to our modern society, its social well-being and the global economy.

IMG_1951In addition, the study of African geology enhances our understanding of the mitigation of a large range of natural hazards that affect society, including:

(1) seismic and seismically induced events (e.g. tsunamis);

(2) long term health risks posed by an excess or deficit of certain trace elements in soils and water, such as radon (radiological hazard), arsenic and fluorine (chemical toxicity), droughts, floods, and desertification, etc

Scientific contributions in all these aspects of geosciences are welcome with particular emphasis on new methodologies and applications to the benefit of the society.
