Short summary
Glauconite and celadonite are green micas which are significant as indicators of palaeoenvironments. They share similar chemical compositions, characterized by their Fe2+, Fe3+ and Mg content despite their white-mica structure; however, the chemical and structural relations were unknown. Their rare coexistence in volcanic rocks due to bacterial activity has allowed us, after an electron microscopy study, to identify a compositional gap between them justified by structural differences.
