📋 Tender Overview
The Geological Mining and Metallurgical Institute Ingemmet published bulletin No. 9 of the L series Geology of the Querobamba Quadrangle Sheets 29o1 29o4 where new information on surface geology has been generated through geological mapping.The mapping includes two detailed geological maps where lithological and structural data are captured which allow to have new stratigraphic proposals being able to redefine and or determine new geological units in addition regional structural control could determine fault systems related to mineral deposits.The studies concluded that the Querobamba quadrangle mainly comprises sedimentary rocks here indicate formations and or groups to which these sedimentary rocks correspond from the Paleozoic and Mesozoic and volcanic rocks from the Cenozoic located within the Western Cordillera of southern Peru.The carbonate rocks of the Upper Triassic-Lower Jurassic found on the Mitu Group correspond to the Pucar Group basin in the center of the country. On the other hand the stratigraphic units from the middle to upper Jurassic correspond to the Yura Group basin in southern Peru. In this sense it is concluded that the Querobamba quadrangle is located on the paleogeographic boundary between the central Pucar and Yura del Sur basins of Peru.From the structural point of view an inverse fault system has been determined that affects the Mesozoic units mentioned above these faults extend between the towns of Racjaya Pampana and Eranja and correspond to tectonic inversion environments conducive to the placement of deposits. minerals these faults extend to the NW and are the regional structural control of porphyry-type deposits such as the Sombrero Project Au-Cu located in the Huanca Sancos province in the Huancapi quadrangle.Bulletin N 9 of series L Geology of the Querobamba Quadrangle comprising a more detailed database with more than 500 geological observation points POG and two digital maps at 1 50000 scale in PDF format and editable ArcGIS format They can be downloaded from the Geocatmin or the Ingemmet Institutional Repository at the following link httpsrepositorio.ingemmet.gob.pehandle20.500.125443117
