    COVER: Cover: Golden yellow crystals of the newly discovered mineral ewingite contain nanoscale uranyl carbonate cages (inset), making it the most complex mineral known by a large margin. The specimen is from the Plavno mine, Jáchymov ore district, Czech Republic. Field of view is ~2 mm. See “Ewingite: Earth’s most complex mineral” by Olds et al., p. 1007–1010 in the November 2017 issue of Geology.
