In 1987 the Corporacion Venezolana de Guayana (CVG), through its mining exploration and development subsidiary Tecnica Minera C.A. (Tecmin) signed a technical cooperation agreement with the U.S. Geological Survey (USGS), with a planned duration of 5 years. This agreement was paid for by CVG and involved technology transfer, training of Tecmin personnel, the acquisition and installation of analytical equipment, and an inventory of the mineral resources of the Venezuelan Guayana Shield. This cooperative agreement was a model of cooperative scientific effort that involved 4 resident USGS scientists, about 20 visiting USGS geologists, geochemists, and com puter specialists, and over 35 Venezuelan geologists, geochemists, computer, soils and forestry specialists. The economic mineral inventory component was a remarkable effort that spanned two languages and two continents. The results are reported in US Geological Survey Bulletin 2062 (including a new geologic map of the southern half of Venezuela) and numerous Tecmin and join Tecmin-USGS reports and maps. This work is based on the extensive earlier work of Mendoza and others (1977) and Bellizzia and others (1981). This paper extends and elaborates upon the USGS Bulletin 2062, and for the first time develops a mineral deposit timeline for the Venezuelan Guayana Shield.
