Geological Significance of Laguna del Carbón

Formation and Geology

The formation of Laguna del Carbón is closely linked to tectonic movements and climatic shifts over millions of years. Here’s a breakdown of its geological significance:

• Tectonic Activity: The Patagonian region has undergone subsidence, creating depressions where water and minerals accumulate.
• Salt Deposits: The lake’s high salinity is due to evaporation, leaving behind thick salt crusts similar to those found in the world’s great salt flats, like Bolivia’s Salar de Uyuni.
• Sediment Layers: Laguna del Carbón provides valuable sedimentary records, offering insights into past climate changes and the evolution of Argentina’s landscape.
