View Ancient History in the Geology of Cape Town

Over Six Hundred Million years ago the rocks in Cape Town were just beginning to form. Over the next hundred million years they went through tremendous trauma and reformation. It is fascinating that we can see into the past by looking at these geological features that are still around today! You can get in your car and go on a beautiful and informative drive through Chapmanâ??s Peak that will take you between layers of Granite and Sandstone. You can hike through craggy mountains and actually sit on the ancient stone that was in place long before your own ancestors.

Geology has become a hot topic, and with good reason. Geology is literally the foundation upon which we stand, and one of the first exciting science subjects. In Cape Town you will find multiple examples of geologic wonders where you can literally see the history of how earth was formed through looking at these awesome and accessible geological examples in the area.

You can choose between Table Mountain, Sea point Promenade, or the numerous other geologically important sites around Cape Town. Or you can even see them all and you will find your self in the same foot prints as Charles Darwin, staring in awe at the ancient history of earth laid out before you in tremendous rock formations.

Along with the interesting geology the rocks offer, you can see how the rocks themselves effect the soil. In the mountains you will find a variety of unique plant classifications. If you drive through the agricultural region you will discover a wheat industry that thrives in the fine grained soils surrounding this mountainous, rocky region.

Cape Town is an area rich in Geological history, that you can see and feel for yourself, in each rocky crag, each compressed formation, and hardened lava flow.

Geology

Although modern geology appeared in the eighteenth century, the Earth was already studied by the Greco-Roman philosophers. The Greek philosopher Theophrastus (371 to 287 BC) described and classified minerals according to their physical properties. The Roman writer Pliny the Elder (23-79 AD) described minerals, crystals and fossils. Also some medieval Muslim scholars proceeded in the field of geology. Al-Biruni (973 – 1048) described the geology of the Indian subcontinent and believed this area was once a sea. Avicenna (981 – 1037) described the formation of mountains as an interplay between tectonic forces and erosion . He believed that mountains had made this form which aproved that the Earth is very old. The Chinese scholar Shen Kuo (1031-1095) independently came to similar ideas.
In Europe one of the first naturalists was Leonardo da Vinci (1452-1519). Da Vinci understood that the fossil shells that he found in the Apennines are indeed remnants of life from earlier times. The Venetian physician Georgius Agricola (1494-1555) was particularly interested in the mining industry. He shared the first rocks in a methodical way: in four groups of consecutive age and consolidation. Nicolaus Steno (1638 – 1686) investigated how rock layers are formed and proposed three laws, with which he was the founder of the stratigraphy.
