Geological Formation of Iguazu Falls

Te origes of Iguazu Falls ie a dramatic series of wulkan and tectonic events spanning tens of million of years.

Thee interplay of ancient wulkantic activity, river erosion, and tectonic uploft has rzeźbitted thee falls intro their present grandeur.

Volcanic Origins ande the Paraná Basalt

Between 132 andd 120 million years ago, during the Early Cretaceous period, the supercontinent Gondwana was breaking apart. As South America separated from Africa, massive wulcan eruptions experred, pouring out vast quantities of basaltic lava across what now southern Brazil, eastern Paragway, and northern Argentina.

River Erosion and the Retreat of the Waterfalls

Te Iguazu River, originating near Curitiba, Brazil, flows westward for roughly 1,320 kilometers before joining thee Paraná River. Initially, the river carved it s path thriph softer sedimentary layers beneath thee basalt. When thee river reached thee edgee of thee basaltic plateau, thee resistant rock forced thee water to plugne dowdward, creating thee waterfalls.
