With its diverse landscapes, rich biodiversity, and exciting adventure opportunities, this UNESCO World Heritage Site promises an experience that will leave you breathless. So, pack your bags, embrace your sense of adventure, and prepare to be captivated by the magic of Phong Nha-Ke Bang.
The Phong Nha-Ke Bang karst landscape is the result of 400 million years of geological history. The oldest karst in Asia, it was formed during the Paleozoic era. Over time, tectonic movements created folded mountains and sedimentary basins, which shaped the diverse topography, geology, and hydrology of the area. These factors also contributed to the formation of the many caves in the park, which are made up of limestone from the Devonian to Carboniferous-Triassic periods.
The park’s current landscape is the result of five major stages in the Earth’s crustal development in the area:
Late Ordovician – Early Silurian period (450 million years ago)
Middle and Late Devonian period (about 340 million years ago)
Carboniferous – Permian period (300 million years ago)
Orogeny period
Cenozoic era (250-65 million years ago)
The initial formation of the caves was likely caused by the uplift of volcanic intrusions that were younger than the limestone. This uplift, along with the movement of the limestone, caused earthquakes, faults, and volcanic eruptions. At the intersections of these faults and volcanic vents, the limestone would have been metamorphosed, transforming it into quicklime (CaO), which is easily dissolved in water.
This quicklime would then have been carried into the cracks and faults of the limestone by water, along with volcanic ash and gravel. In a water environment, this ash would have turned into soft mud, silt, and kaolin, which could easily be washed away by water or deposited in cracks and cavities due to its density being 0.3-0.4 g/cm3 higher than limestone.
Water played a key role in shaping the caves, both by clearing away debris and by creating the stalactites and stalagmites that we see today.
