Ganomalite

  

 

  

Ganomolite is a rare species found in few specimens of any size. This specimen has abundant ganomalite as anhedral crystal grains in calcite and jacobsite (magnetite) matrix. The high luster of ganomalite readily distinguishes it from calcite. The largest grains are about 0.5 cm across. There is also a colourless mineral present which fluoresces light violet under SW UV light which John suspects is berzeliite.
