Description

A manganese ore specimen from Spain. Dr. Schur identified not only todorokite but also chalcophanite on the specimen, leaving a question mark at hydrohetaerolite. I think the last would have to be analyzed by other means.

With or without: a very interesting and attractive specimen wth nice, greenish hues on the 'kidneys'.
