Cobaltomenite is a hydrous Cobalt Selenium Oxide. Magenta aggregates of microcrystalline Cobaltomenite. Ferroselite is an Iron Selenium with small grey to black elongated crystals which I do not see these with a loop but listed on the tag. This was probably collected by Joe Marty and gifted to Dana Wilson MD for his collection. |
