Carbonate-Apatite - var. Dahllite
Little Mountain District, Big Horn County

pre Tucson 2015 update
An oddity in the Apatite family, this form of Carbonate rich apatite is not seen very often. This specimen is well over 30 years old from a small find, it shows well the structure and form, it is a bit similar (with some notable differences) to Ukrainian nodules. Rare and in fine condition.
