Resumen
El afloramiento de Formación Navidad ha sido fuertemente estudiado desde Charles Darwin a la actualidad. Aun así, no existe total consenso en el ambiente de formación, la edad y la distribución estratigráfica. Son muchos los elementos geológicos que podrían contribuir con información para descifrar su génesis y evolución. Estos elementos constituyen al patrimonio geológico del sector, importante reconocerlos, valorizarlos y difundirlos para su futura preservación. Además, se reconocen otros elementos de la geodiversidad con otros valores turísticos y educativos. En los últimos años, los locatarios han trabajado en rescatar y aprovechar su patrimonio histórico, cultural y geológico. La información que entrega la evidencia de dichos elementos geológicos en lo que fue la evolución de los depósitos marinos de antearco, es relevante y clave para entender y correlacionar los eventos geológicos desde el Mioceno con la historia geológica de Chile y por tanto también repercute en la historia geológica del mundo. Se destacan en este trabajo como geopatrimonio intrínseco los foraminíferos de Navidad, las concreciones de Navidad, las estructuras sedimentarias de corriente, las trazas de Navidad, el registro de moluscos, el paleoseep, el estratotipo de base y el estratotipo de techo. Por otra parte, los elementos de la geodiversidad in situ con fines educativos y turísticos vale la pena reconocerlos, ya que proveen de las atracciones principales para que se desarrolle el turismo y la actividad económica. Se reconoció la geomorfología de la desembocadura del río Rapel, en la que se desarrolla actividades turísticas como kayak, buceo, pesca entre otros.
The outcrop of the Navidad Formation has been heavily studied from Charles Darwin to the present. Even so, there is no complete consensus on the formation environment, age and stratigraphic distribution. There are many geological elements that could contribute information to decipher its genesis and evolution. These elements constitute the geological heritage of the sector, it is important to recognize, value and disseminate them for their future preservation. In addition, other elements of geodiversity with other tourist and educational values are recognized. In recent years, the tenants have worked to rescue and take advantage of their historical, cultural and geological heritage. The information provided by the evidence of these geological elements in what was the evolution of the forearc marine deposits is relevant and key to understanding and correlating the geological events since the Miocene with the geological history of Chile and therefore also has repercussions on the geological history of the world. The Navidad foraminifera, the Navidad concretions, the stream sedimentary structures, the Navidad traces, the mollusc record, the paleoseep, the base stratotype and the roof stratotype stand out in this work as intrinsic geoheritage. On the other hand, the elements of in situ geodiversity for educational and tourist purposes are worth recognizing, since they provide the main attractions for tourism and economic activity to develop. The geomorphology of the mouth of the Rapel River was recognized, in which tourist activities such as kayaking, diving, fishing, among others, are developed.
