Valencia County, New Mexico
Yellow-green grains in sandstone, plentiful, with associated zippieite. We got this material in 1957. The uranopilite is fluorescent greenish, the zippieite is fluorescent yellowish. Both fluoresce under short- and long-wave ultra-violet light.
I have a few more specimens of this material, please email me for a quote if interested.
