Yellow Jahnsite crystals to less than 0.5mm in thick growth across the Heterosite matrix. There are some variations in color from yellow to a darker greenish yellow and to a red Jahnsite. I cannot differeniate which Jahnsites these are based on color, but they are not the original (CaMnMg) species.
On the backside of the specimen are some nice little acicular crystals of Segelerite. The one in the photo is about 0.5mm. There are three more crystals not seen.
The purple you see are dark Leucophosphite crystal grains. There is one nice crystals. The white acicular groups are carbonte apatite. There is also a little Rockbridgeite, minor Tavorite, and other minerals.

Yellow to yellowish green Jahnsite to about 0.5mm in clusters to 3mm. It is associated with dark green to rusty red Mitridatite. If I had to guess it is Jahnsite-(CaMnMg).

Yellow Jahnsite crystals to about 0.5mm with good coverage. There may be two different types of Jahnsite as another is more green than yellow, if you can go by color. Other minerals include dark red Rockbridgeite and dark green Mitridatite.
