📋 Tender Overview
The Geological Mining and Metallurgical Institute Ingemmet carried out the geological mapping of the Jaqui 31 quadrangle sheets 2 and 4 located on the western slope of the Western Cordillera between the province of Lucanas in the department of Ayacucho and the province of Caraveli from the department of Arequipa. The research describes the lithological and structural characteristics of the Jaqui 31 quadrangle which is made up of more than 50 plutonic rocks. Where the detailed mapping of the super units of the Coastal Batholith was carried out with ages ranging from the Jurassic to the Cretaceous. After regional geological mapping at 150 000 scale up to seven 07 plutonic units have been determined and characterized varying from the Jurassic to the Cretaceous period. For volcanic rocks the Rio Grande Formation was determined as part of the Middle Jurassic volcanism. For sedimentary rocks the quartz sandstones and siltstones of the Yauca Formation were mapped with greater precision. The area has four fault systems East-West system this being the oldest event which controlled the location of the intrusive bodies of the Jurassic Northeast-Southwest System sinestral bearing structures Northwest-Southeast system sinestral strike structures related to Gold Au veins and the North-South system structures related to swarms of monzogranite dikes. The review and characterization of sedimentary units that outcrop in the eastern zone of quadrant 312 suggest simplifying the range of the Yura Group formations in the Yauca Formation. The investigations have been reflected in the geological bulletins bulletin N 21 L Geology of the Jaqui quadrangle sheet 314 httpsrepositorio.ingemmet.gob.pehandle20.500.125443141 and bulletin N 23 L Geology of the Jaqui quadrangle sheet 312 httpsrepositorio.ingemmet.gob.pehandle20.500.125443143 accompanied by two maps in PDF format and editable ArcGIS. All the information can be downloaded from the Geocatmin or the Ingemmet Institutional Repository.
