1. Geological Genesis: The Process of Karstification and Cave Formation
The formation of the Puerto Princesa Underground River is a tale of ancient seas, natural forces, and millions of years of transformation.
The Process of Karstification
Long ago, the region that is now Palawan was submerged under ancient seas. Over time, thick layers of coral-based limestone were deposited on the seafloor. As tectonic movements uplifted these deposits above sea level, conditions became ripe for a geological process known as karstification. Rainwater, slightly acidic from dissolved carbon dioxide, seeped into the porous limestone, gradually dissolving it over millennia. This slow dissolution carved out a complex network of tunnels and caverns that form the basis of the cave system.
Formation of Speleothems
As mineral-laden water dripped from the ceiling of the cave, it left behind deposits of calcite, which slowly built up into stalactites. Conversely, when water pooled on the cave floor and then dripped down, stalagmites formed. In some areas, these formations eventually joined to form impressive columns, providing a living record of the cave’s evolutionary process. The gradual pace of these changes—often mere millimeters per century—underscores the fragility and timelessness of the cave’s features.
