| Species: | Metanatroautunite | |
| Formula: | Na(UO2)(PO4)(H2O)3 | |
| Comments: | "The metanatroautunite forms crystals and clusters up to 4 mm across on limonite-coated joint planes and in miarolitic cavities. Crystals may appear to be aggregates of intergrown plates with slightly rounded edges. In some crystals with more blocky habits, these plates may be separated. The upper surface of these crystals tend to be slightly concave and crinkled partly due to dehydration. Rare intergrowths with saleeite or torbernite occur. Metanatroautunite is initially difficult to distinguish from saleeite at Lake Boga. However, metanatroautunite tends to be translucent with a pearly or slightly greasy lustre, and be bright lemon yellow. This colour may be slightly more intense on the edge than on the upper face. Saleeite at Lake Boga is generally transparent and more golden yellow." | |
