Interesting Facts About World's Oldest Mountains That Will Surprise You

The Earth, with an age of about 4.54 billion years, is home to some of the oldest mountain ranges that serve as majestic markers of the planet's long and intricate geological history. These ancient mountains, more than a billion years old, stand today as silent witnesses to the processes of continental drift, geological transformations, and the passage of time, each with a story to tell about the Earth's formative years.

Barberton mountains

Leading the list of venerable mountain ranges is the Barberton Greenstone Belt, also known as the Makhonjwa Mountains, located in South Africa. Dated at approximately 3.5 billion years old, these mountains represent the oldest known formations of their kind on the planet. Despite their modest elevations, the Barberton Mountains are distinguished by their unique greenstone composition, the result of intense volcanic activity and sedimentation on the ancient Kaapvaal Craton. This area's layered rock formations provide a rare window into early continental evolution and the dawn of life on Earth.

Hamersley range 

Following closely is the Hamersley Range in Western Australia, with an age of around 3.4 billion years. Situated on the Pilbara Craton, these mountains were formed from the remnants of volcanic islands and ancient sea basins. The Hamersley Range is renowned for its extensive deposits of iron ore, which paint the landscape in vivid reds and browns, creating a striking natural spectacle.

Waterberg mountains 

South Africa's Limpopo Province is home to the Waterberg Mountains, estimated to be 2.8 billion years old. Set within the expansive Waterberg Biosphere Reserve, these mountains are characterised by their prominent red sandstone cliffs and plateaus, dating back to the Proterozoic Eon. The Waterberg Mountains offer a captivating look into Earth's early geological periods.

Magaliesberg mountains

Lastly, the Magaliesberg Mountains, found in South Africa's North West Province, boast an age of approximately 2.3 billion years. Originating in the Archean Eon, their formation was a result of sediment accumulation and compression in an ancient sea. Presently, the Magaliesberg's rugged landscape, with its steep cliffs and unique rock formations, continues to fascinate and inspire.
