N2  - The importance of this volume on the mineral resources of Venezuela lies not only in its delineation of the vast mineral richness of the Guayana Shield but also in its illustration of the productive cooperation between the Corporación Venezolana de Guayana and the U.S. Geological Survey. Geologic research described herein regarding the wise use of mineral resources is a model of cooperative scientific effort that can be used to assist the making of decisions at the highest levels of the government. This information can provide the basis for long-range mineral production and land use policy, for planning strategies for mineral exploration and development, for the direction of future research, and for expanding the inventory of mineral deposits of Venezuela. Special features of this cooperative project included the creation of a mineral reources data system file and the use of mineral-deposit models to estimate the mineral resources of mineralized areas, both known and suspected, in the Guayana Shield and adjacent areas
