Summary

[edit]
Description
English: Köttigite
Locality: Ojuela Mine, Mapimí, Municipio de Mapimí, Durango, Mexico (Locality at mindat.org)
Size: 5.4 cm x 4.4 cm x 2.2 cm
Köttigite is hydrated zinc arsenate and this very fine rarity is from Mina Ojuela, known for the best examples of the species. The egg-shaped, oval vug is totally lined with lustrous, bluish-gray, parallel-growth, crystal clusters. These crystals are extremely robust for the species, and show stereotypical crystal habit. Köttigite is hydrated zinc arsenate hydrate and parasymplesite is hydrated iron arsenate, and because they have such a similar appearance they can only be distinguished by chemical analysis in a lab. There is an interesting discussion of this series in the Min. Record, V. 7, #4, p. 186. In any case, this piece is likely the köttigite. Old material not found in over 30 years and there will not be more as these levels of the mine are flooded. Ex. Howard Belsky Collection.
