Dypingite under shortwave UV Light

Parts of the dypingite specimen shown in photos DYP7b and DYP7c fluoresce bright green under SW ultraviolet light due to a later mineral deposited as minute grains on the spheroids.  These grains are visible, but not identifiable, under a hand lens. Willemite is an obvious possibility, but former owner Richard Bostwick suspected it might be a uranyl-activated mineral, possibly because znucalite, a green-fluorescing, post-mining, Zn-U carbonate mineral, had been found nearby.
