abstract

  • Thick and continuous vegetation cover, usually considered a constraint for geologic mapping with remote sensors, has been used as the main source of spectral data for interpretation of Landsat images from the mid-section of the Caroni River basin, Venezuela. The basic assumption made was that spectral properties of vegetation were a direct function of the nature of the underlying bedrock. This approach, when combined with geomorphic criteria, proved to be a valid one for regional geologic cartography. Three geologic domains defined in the interpretation stage correspond satisfactorily with the three major rock provinces in the area. Furthermore, 6 areas were selected as potential targets for diamond placer exploration; 5 of them were verified in the field as alluvium, and 4 of the 5 diamond placers. -Authors
