Vicuña Mackenna Batholith, Geological batholith formation in Antofagasta Region, Chile.
The Vicuña Mackenna Batholith is a large igneous rock formation in the Chilean Coast Range that formed when molten material cooled beneath the surface. The structure displays multiple rock types that developed during different geological periods.
The batholith formed during the Jurassic and Cretaceous periods as different pluton units developed over roughly 94 million years. These processes were part of larger magmatic activity in South America.
Scientists and researchers from various institutions visit this geological site to study the composition of rocks and understand South American tectonic movements.
The site is remote and requires specialized equipment and local guides for safe visits. Travelers should be prepared for harsh conditions in this northern desert region.
The Paranal Unit is the largest section and contains six different rock types that formed during cooling. This variety of rocks in one location is rare to witness.
