The magic of electrons












The last few weeks have been swamped with work on various sandstone core samples. Part of the fun is looking at really tiny things under a scanning electron microscope. These images are mostly of quartz cement in really old aeolian sandstones. I confess, one of the pictures shows a potassium feldspar overgrowth - can you guess which one? These pictures make neat screen savers, if you are into quartz crystals and hairy illite (or is that "fred" illite? -since Bucky is now Steve, why shouldn't hairy change his name, too?).
