This site comprises more than 100 images of whole petrographic thin sections, mostly in paired plane- and polarized-light views. Images are hosted at gigapan.com, and most are >20,000 pixels in long dimension, which allows smooth zooming from whole-image scale to areas ~1 mm across. The atlas includes terrestrial samples, lunar samples, and meteorites. It is slanted heavily toward igneous rocks.
