Most people equate geology with dull, grey rocks, but petrology Professor Bernardo Cesare is tapping into their spectacular beauty with his MicROCKScopica project. Using a standard technique for analyzing mineral composition of rocks, Cesare cuts and grinds sections of rock into 30-micron-thick slices (that's three-hundredths of a millimeter), mounts them onto microscope slides and shines cross-polarized light through them. The result is a kaleidoscope of color that is as informative as it is beautiful.
