dc.description.abstractEl páramo de Chingaza hace parte de uno de los sistemas ecológicos y ambientales exclusivos de la zona neotropical e intra montano Andino de Colombia. La Laguna Seca, es uno de los sistemas heredados lagunares del páramo por eventos glaciares del Pleistoceno Tardío, con una fuente de aporte reducida, permitiendo la conservación del sedimento y un registro continuo desde los 16.329 años cal BP al presente. Este estudio busca identificar condiciones ambientales y cambios relacionados a la evolución del sistema climático a partir de una descripción facial detallada y la suma de análisis mineralógicos, isotópicos y geoquímicos para un sondeo de 414 cm de sedimento recolectado en la Laguna Seca. El análisis permitió diferenciar 8 zonas climáticas relacionadas con condiciones de sequía- humedad, con bajas y altas temperaturas que reflejan en su mayor parte eventos estadiales e interestadiales de talla global reportados en Colombia para el Cuaternario. De esta forma, se evidencia que los cambios sedimentológicos juntos con sus rasgos químicos, son proxies que responden a cambios ambientales, siendo de gran utilidad para estudios paleoambientales de las zonas paramunas de alta montaña.

dc.description.abstractThe Chingaza one part of one of the exclusive ecological and environmental systems of the neotropical and intra-montane Andean zone of Colombia. Laguna Seca is one of the lake systems inherited from the paramo by glacial events of the Late Pleistocene, with a reduced source of contribution, allowing the conservation of the sediment and a continuous record from 16,329 cal years BP to the present. This study seeks to identify environmental conditions and changes related to the evolution of the climate system based on a detailed facial description and the addition of mineralogical, isotopic and geochemical analyzes for a survey of 414 cm of sediment collected in Laguna Seca. The analysis allowed us to identify 8 climatic zones under conditions of drought-humidity, cold and heat that mostly represent stadial and interstadial events of global size reported in Colombia for the Quaternary. In this way, it is evident that sedimentological changes, together with their chemical traits, are proxies that respond to environmental changes, being very useful for paleoenvironmental studies of high mountain paramunas areas.
