Yellow and blue magnesiocopiapite
and aluminocopiapite, white epsomite and wilcoxite, and blue chalcanthite coat the hematite walls.
Copiapite and its Al and Mg-analogs, aluminocopiapite and magnesiocopiapite, are relatively common secondary minerals in old workings of the Andrassy I, II and the Vilmos sections.
Magnesiocopiapite is easily found and identified by its bright yellow color, The distinctive yellow-green hue of slavikite can perhaps be noted by the sharp-eyed, but the amounts are generally so small that it is difficult to find.
Alunogen is found as thin colorless plates with elongated pseudohexagonal outline (almost micaceous in aspect), about 0.3 mm in size, associated with magnesiocopiapite on rock surfaces and crevices.
If the new mineral is clearly and simply related to an existing one, it is very desirable that this relationship be indicated in the new name, e.g., clinoenstatite for the monoclinic dimorph of enstatite, or magnesiocopiapite
for the Mg analog of copiapite.
