Striations and strata - horizontal layers of material such as sedimentary rocks - are common inspirations for today's architects, as this archive of geologically inspired projects shows (+ slideshow).
See more about the projects in the slideshow above - as well as many others - by clicking on the image above or scrolling through our strata and striations tag.
