Tyuyamunite and Calcite from Grants Mining District, New Mexico, USA

Micromount specimen of yellow Tyuyamunite and Calcite from Grants Mining District, New Mexico, USA.

#1 - This specimen was part of Roger Harkers collection and has three of his labels glued to the perky box it comes mounted in. One had detached and has been stuck back on with a conservation grade tape.

The specimen is mounted with glue into the box. Ex. Roger Harker, L. Genot collections.

While this is a radioactive mineral, it is so small that I was unable to detect much, if any increase in radioactivity from the specimen.
