Overview

East Africa’s Geology was First Mapped in 1900 by Gregory Rift.

East Africa Rift System subsequently taking its Name after the Geologist, Gregory Rift.  The Earliest Gold Discovery in East Africa was made in 1890 by German Prospectors around Lake Victoria Area.  Since then Broad Spectrum of Geology Studies have been undertaken to Study East Africa’s Geology’s Evolution and Mineralization. Geophysical and Geochemical Surveys to Collect Data and Map East Africa’s Natural Resources have been undertaken by Independent Geologist, Geological Survey Departments of Various, Countries Including Canada, Britain and Australia. Others include Non- Governmental Organization such as United Nations Development Programs, Multinational Mining Companies such as Brocken Hill Propriety, De Beers, and Anglo America.

Individual Governments also over the last Decade have also Proactively Undertaken Mineral Exploration Surveys to Identify and Map Natural resources as Part of Initiative to Promote Investment into the Extractive Sectors. Mostly Engaging the Modern Exploration Technology to carry out Air bone Survey and Document the Data on Mineralization on Geo – Portal Cadastral.

The Development of New Advance Exploration Technology has had a Profound Positive Impact on Mineral Exploration and Deposit Discoveries. In the last decade significant advances have been made on Proven Geophysical methods and Techniques to interpret and Visualize Geophysical Data.  One of the most significant recent advances in Geophysics is the routine 3D Inversions of Potential Field Data.

Progress in Computing power and Software Innovation has enhanced Data integration and inversions to be applied to a variety of Problems from Modeling to desecrate targets of Region Geology.  A review of Discovery methods by Experts Indicate that Understating the Geological feature is the Key Element in both Greenfield and Brownfield Exploration. Therefore ultimately application of proven and emerging detection techniques in close integration with Geology is remain important in underpinning the Future Mineral Exploration Programs.

Tanzania

Tanzania is Fortunate in possessing a Geologic Mineral Database, which is virtually complete work done since mid 1930s.

Various Reconnaissance Geophysical and Geochemical Surveys have been undertaken by Various Organizations including the Government of Tanzania, United Nations Development Programme (UNDP) and Global Mining Companies including Rio Tinto Zinc, Brocken Hill Propriety (BHP), De beers and Anglo-American.

Two widely used publications that have classified Minerals deposits into Formal models in Tanzania’s Geology and Metallogeny is ECKSTRAND (1984) of the Geology Survey of Canada & COX|SINGER (1986) of the U.S Geological Survey.

The Data and Documentation for the Comprehensive studies are Stored in the Archives of the Geology Survey of Tanzania Institute (GST) Dodoma. Topographic maps and Aerial photographs are available at the Department of Lands and Surveys in Dar es Salaam. Others Data Including Geochemical Analysis is a can be found in the Archives of the Southern and Eastern African Mineral Centre (SEAMIC).

Kenya

The Ministry of Mining is currently in the Process of Undertaking a Reccoinssance Air-bone Survey to take inventory and Map Kenya’s Extractive Resources.

There has been Geology studies Undertaken in the past Dating back to the 1950’s by independent Geologist, London, South Africa, Canadian and U.S Universities. The Nairobi University Department of Geology Science is the Kenyan Institution that carries out Research and Studies into the Kenya’s Geology. Dr. Christopher Nyamai Helms the Department where Data is Stored in the Institution. The University has Released Various Publications.

  • APPRAISAL OF MOZAMBIQUE BELT BY AFRICAN JOURNAL OF SCIENCE & TECHNOLOGY SCIENCE AND TECHNOLOGY SERIES VOL. 4.
  • GEOLOGY & ORE MINERALIZATION OF ARCHAEAN OF WESTERN KENYA BY DEPARTMENT OF GEOLOGY SCIENCES NAIROBI UNIVERSITY.
  • MINERALOGY & GNEISS METALLIC MINERALIZATION OF KENYAN COAST BY DEPARTMENT OF GEOLOGY SCIENCES NAIROBI UNIVERSITY.
