ⓘ Cobaltomenite

Formula: CoSeO3 · 2H2O

Description: New analysis done in 2021 (SEM, EDAX) by Joy Desor from a specimen in the collection of Elmar Lackner. Analytical data shows a Co:Ni ratio of approx 3:1 confirming Cobaltomenite. Notice the old entry because the similarity to Ahlfieldite: Much of the material called "cobaltomenite" from El Dragon was identified only by XRD and is really pink cobalt-bearing ahlfeldite. Color is a very unreliable guide, as it takes only a minor amount of Co to change the color from green to pink or purple.
