Långban Minerals – January 23

Långban is one of the great mineral localities of the world. The unusual chemistry of manganese and beryllium together with reduced conditions has yielded over 70 new minerals, and the worlds best examples of native lead (in crystals to 5 cm). Early scientific study of these minerals lead to our modern understanding of crystallography and paragenesis. There is an excellent book on the subject, available from Mineralogical Research Company and from Excalibur Mineral Company.
