The layered rock formations near Faro, Portugal, are composed primarily of limestone (calcareous sandstone), a sedimentary rock formed by the accumulation of marine organisms such as shells, coral, and microorganisms. These formations date back to periods when the area was covered by shallow seas millions of years ago. The characteristic yellow-brown or ochre color is primarily due to the presence of iron-bearing minerals and the specific composition of the rock. The rocks are susceptible to differential erosion, meaning that softer layers are eroded away faster than harder layers, creating spectacular formations such as caves, arches, and sea stacks (like the famous Benagil Cave).
The almost melted look of the surface of the rock formation, reminded me of the one from the pic below however the surface of the rock formation in this pic changed because of the sea. (Location: border area France/Belgium)
