Resumen
Las estrategias de geoconservación de los elementos valiosos de la diversidad natural, creadas a partir de inventarios, valoraciones cualitativas y cuantitativas de la geodiversidad, son una herramienta de análisis territorial que busca la protección y la adecuada gestión del patrimonio geológico. Es por ello, que en este trabajo se creó un inventario de geositios en la Cordillera Occidental de los Andes Centrales en la Región de Antofagasta, entre el complejo volcánico San Pedro – San Pablo (21° 54'S - 68° 24'O) y el sistema geotermal El Tatio – La Torta (22° 23'S - 67° 59'O), los cuales fueron caracterizados y valorados cuantitativamente para proponer medidas previas de conservación. La mayoría de los sitios identificados están agrupados en el contexto geológico “Volcanismo Neógeno Superior-Cuaternario y Campos Geotermales”, en base a los contextos geológicos definidos para caracterizar el patrimonio geológico nacional. El área presenta una amplia gama de productos volcánicos e importantes elementos del patrimonio cultural, identificando 7 geositios de alto valor científico: el Volcán San Pedro y cono La Poruña, el Volcán Paniri, el Domo Chao, el Valle glaciar Linzor, el Campo geotermal El Tatio, el Basamento ignimbrítico de Alto Loa, y la Laguna Inca Coya y restos fósiles de la Megafauna (p.ej., Megatherium sp.). Los geositios propuestos son los más representativos del área en torno a los contextos geológicos que representan, y es por ello, la importancia de su conservación.
The geoconservation strategies of the valuable elements of natural diversity, created from inventories, qualitative and quantitative assessments of geodiversity, are a tool for territorial analysis that seeks the protection and adequate management of the geological heritage. That is why, in this work, an inventory of geosites was created in the Western Cordillera of the Central Andes in the Region of Antofagasta, between the volcanic complex San Pedro - San Pablo (21° 54'S - 68° 24'W) and the geothermal system El Tatio - La Torta (22° 23'S - 67° 59'W), which were characterized and quantitatively assessed in order to propose preliminary conservation measures. Most of the identified sites are grouped in the geological context “Upper-Quaternary Neogene Volcanism and Geothermal Fields”, based on the geological contexts defined to characterize the national geological heritage. The area is characterized by contains a wide range of volcanic products and important elements of cultural heritage, identifying 7 geosites of high scientific value were identified: San Pedro volcano and La Poruña cone, Paniri volcano, Chao dome, Linzor glacier valley, Tatio geothermal field, the Ignimbritic basement of Alto Loa, and the Inca Coya Lake and fossil remains of megafauna (e.g., Megatherium sp.). The proposed geosites are the most representative of the area around the geological contexts that they represent, and that is why, the importance of their conservation.
