First off, let’s look at desert rose. Formed from the minerals gypsum or barite together with sand, this geometric, angular rock suggests maze-like ultra-modern construction. Think staircases and skywalks – now that would be fun building to explore.
Next up: pyrite suns. Pyrite, as you may well know, is commonly referred to as “fool’s gold,” but I bet you haven’t seen it in this radial formation before. Pyrite suns are found in shale near Sparta, IL. One theory holds that they’re actually formed when the pyrite replaces the fossilized remains of a yet un-identified organism. I’d love to see these used in an exterior veneer! Unfortunately, they’re extremely fragile and would be nearly impossible to keep intact.
Finally, I suggest Petoskey stones. The unusual pattern on these rocks is actually revealing of the stone’s prior form as coral. When glaciers came through the area, they broke off and smoothed pieces of the bedrock – the petoskey stones. They’d be great material for buildings in rainy climates. Why? These chameleon rocks resemble chalky, dull limestone until wet – that’s when their intricate designs are made evident.
I’ve voiced the need for brilliancy of color in new architectural creations, and now I’m suggesting texture and pattern as well. I look forward to the new buildings!
