PhotosIncorrect species identification for the small lemon yellow tabular crystals

Stolzite

Broken Hill, Broken Hill district, Yancowinna Co., New South Wales, Australia

I am pretty sure that the lemon yellow crystals associated with the larger sized sherry brown stolzite is not raspite but small tetragonal crystals of stolzite in a more tabular form. Raspite is monoclinic and its colour is almost always a sherry brown and is almost always in elongated crystals. Stolzite that was collected from the BHP mine of Broken Hill in its very early days can be found often in two colours with each type having a different crystal form. I also have never seen crystals of raspite from Broken Hill that is this lemon yellow colour and tabular form. What do you others that specialize in the minerals from Broken Hill think?

The tiny prismatic crystals in the lower left corner of the enlarged image could be raspite, but just may be end-on tabular stolzite too. Agree that the large blocky and tabular yellow crystals are stolzite.

Agree with Demetrius. The photo captions should definitely be corrected.

I agree with Demetrius, but hard to be sure from the photo.

Then it's probably better to mark it as " identity uncertain " and put in " user gallery ".

Keep safe.

I would leave it as a nice stolzite photo and note in the description that raspite is possible.
