Geología y cartografía de sitio de interés geológico en la Granodiorita Paso de Icalma entre los lagos Aluminé y Moquehue, Villa Pehuenia, Neuquén.

Abstract

In the locality of Villa Pehuenia, in the central-west region of the Neuquén province, a series of geological interest sites are proposed, associated with endogenous processes studied in the Paso de Icalma Granodiorite (Lower-Upper Cretaceous) and other igneous components that conform the North Patagonian Batholith in the region. Background information was analyzed, and the study area was mapped using satellite images, which were processed to perfom a supervised classification of surface components using parametric methods in ENVI and QGIS. Field samples were described petrographically, and the sites were evaluated based on predefined criteria by Miranda (2018). Based on their characteristics, four GISs were established: “Batea Mahuida Sur- Paredón Viejo,” “Batea Mahuida Norte,” “Playa Lunares,” and “Lago Moquehue,” and a webpage was created. Finally, coordination was carried out with public agencies for their implementation in Villa Pehuenia- Moquehue as a geotourism offering and a scientific-didactic proposal.
