Report on the geological survey in the Urubamba river inferior area of the Republic of Peru (Phase I)

Abstract

This report describes results of the first year's survey in FYl998, implemented in the Urubamba river inferior area of the Republic of Peru, under the technical cooperation for the mineral exploration. The survey was conducted with an aim to effectively select promising zones from the extensive survey area in a short period of time, by means of satellite image analysis, existing data analysis and integrated studies of survey findings of an arca upstream of the Amazon in eastern Peru, which covers the Ucayali River Basin and its upper streams, the Urubamba and the Tambo, where the metallogenic zoning has not been clarified in detail. Simultaneously, the technology transfer to the INGEMMET - Instituto Geológico Minero y Metalúrgico, the Peruvian counterpart for the survey, was carried out concerning the methods of survey and analysis. Collection and analysis of existing data and the satellite image analysis for the purpose of the technology transfer was executed from January 24 to February 23, 1999. The Urubamba river inferior area covers an area of about 65,500 km2, spreading over the 28 quadrangles of the 1:100,000-scale topographic map issued by the National Geographical Instituto of Peru. In Phase 1, the analysis of the JERS-1 SAR images was conducted of the 15 quadrangles in the western part of the mentioned area, situated at 75° to 70°30' W of longitude and 11° o to 9°30' S of latitude, whilst the existing data analysis was conducted of the entire Urubamba river inferior area.
