Last morning in Namibia 🌅 Up with the sun, and the final tourist attraction on our list was just 5km up the road from camp — Giant’s Playground.
The Giant’s Playground forms part of the Keetmanshoop Dolerite Complex (also known as the Dolerite Swarm) and showcases a series of impressively weathered dolerite d***s.
Now, the geological and geomorphologic process behind how these were formed might bore most of you 😅 — but for those interested, I’ll keep it short 😉
Molten rock, or magma, is generated below the Earth’s surface and rises because it’s slightly less dense than the surrounding rock. Sometimes, it even erupts above the surface, forming volcanoes 🌋
Sills are flat-lying lava sheets injected into horizontal sedimentary rocks, which can reach several kilometres in thickness and cover vast areas.
At higher levels in the Earth’s crust, rocks are cooler and more brittle, so magma moves differently. Pressure in the magma chamber forces the lava upward, where it pushes into cracks and fissures, eventually solidifying to form what’s called a d**e. These can vary in thickness and extend for anything from a few metres to several kilometres.
Geography lesson ✅ You’re welcome! 😄
