How did the Marble Caves in Patagonia form?
The magnificent Marble Caves have formed over the last 6000+ years as the water melted from the nearby glaciers filling up General Carrera Lake and washing up against these solid rocks slowly carving out intricate caverns, columns, and tunnel systems.
How old is marble caves of Chile?
6,000 year old
Welcome To The Marble Caves, Chile Known across the world as the most stunning and intricate cave network on Earth, the Cuevas de Marmol is a 6,000 year old cavern made of solid marble. The breathtaking spot has been carved by the crashing waves of Lake General Carrera of Patagonia in Southern Chile.
Where are Patagonia Marble Caves?
The Marble Caves (also known as Cuevas de Mármol) are located in the Patagonian Andes, on a peninsula of solid marble. This unique geological formation sits in waters shared by Argentina and Chile, and is only accessible by boat.
What makes the Marble Caves unique?
The amount of light entering the cave and the water level of the lake is constantly changing. This makes each visit to the caves unique. During spring, the water level of the lake is at its lowest point. The lake gets its water from the nearby glaciers, hence they will not have melted by then.
How were the Marble Caves created?
They were created by wave erosion. The waves continuously splashed against the walls of the marble. The sediment in the lake eroded away the walls. It also smoothed and shaped the marble.
What are the Marble Caves in Chile made of?
While these caves are called the marble caves, they are actually made up of 95% calcium carbonate. The caves are a mineral formation that were eroded by water long ago to form them. The ocean waves lapping at the calcium carbonate over a course of 6,000 years is what made these beautiful structures look how they do.
How were the Marble Caves in Chile formed?
Formed by 6,000-plus years of waves washing up against calcium carbonate, the smooth, swirling blues of the cavern walls are a reflection of the lake’s azure waters, which change in intensity and hue, depending on water levels and time of year.
What is the size of the Marble Caves?
Both names are internationally accepted. The lake has a surface of 1,850 km² of which 970 km² are in the Chilean Aysén del General Carlos Ibáñez del Campo Region, and 880 km² in the Argentine Santa Cruz Province, making it the biggest lake in Chile, and the fourth largest in Argentina.
Are the Marble Caves in danger?
The caves are inaccessible by road and can only be reached by boat. Tourists board a boat from a nearby remote town known as Puerto Rio Tranquillo. The biggest threat to the caves is the water. The erosion that has shaped the caves may very well be its undoing in the future.
What type of rock is Marble Caves made of?
Marble is a non-foliated metamorphic rock. Metamorphic rocks are formed when sedimentary rocks get compacted with heat and pressure. The Marble Caves’ features are caverns, pillars and tunnels. The cave and it’s features are made of monoliths of marble, created about 6,000+ years ago.
What animals live in the Marble Caves?
Although so far beneath the surface, these caves are home to numerous species, including bats, freshwater shrimps, moths and various species of spider.
What continent is the Marble Caves in?
The Marble Caves can be found near the border of Argentina and Chile, on General Carrera Lake in Patagonia which is the fifth largest lake in South America. These amazing natural wonders, are a unique geological formation, featuring a number of caverns, tunnels and pillars, in monoliths of marble.
