Metamunirite

Field of view: 4 mm. From the personal collection of Pat Haynes, who discovered metamunirite in 1986.

Very large crystals of yellow-white Metamunirite on sandstone matrix. These are some of the largest well formed crystals of Metamunirite I have seen, the longest is about 3mm long. I obtained this specimen from Michael Cline, who collected it. I was told that single crystal XRD analysis was done on this specimen to confirm that it is Metamunirite. ...

3.3 x 2.9 x 2.1 cm Metamunirite is a very rare sodium vanadate, only found in a handful of world localities. The species was approved in the early 1990s, and the type locality is the lesser known Burro Mine in San Miguel County, Colorado (in the San Juan Mountains). This piece features micro acicular white intergrown "fibers" of metamunirite on ...

A spherical spray of white-light tan crystals of Metamunirite on a matrix of sandstone. I obtained this specimen from Michael Cline of Catalina Minerals, who collected it. I was told that single crystal XRD analysis was done on this specimen to confirm that it is Metamunirite.

White, acicular crystals of metamunirite. Rolf Luetcke specimen and photo.

Thanks to Travis Olds. This is a comparison of SW UV fluorescence, visible light, and MW UV fluorescence images. With the 5 W LED flashlights that I use, the actual MW response is stronger than the SW response. See below for details. In both UV images, the reddish glow is from metamurinite. As far as I can tell, these responses have not ...

White acicular Metamunirite crystals on unidentified matrix Acquired from Paul Mestrom

This is a comparison of MW & SW UV and visible light images showing another part of the specimen. See the parent images for a discussion of IDs and UV responses. The only thing new in these images is the “bright shiny object” at left center. Under a scope it looks as if it is embedded in the matrix. An attempt to blow it away using an ...

One face of a 6 x 4 x 4 cm block of coarse-grained, porous, highly bleached sandstone is covered with 2 mm white botryoids of Metamunirite on light green Metarossite. The Metamunirite fluoresces a medium strength orange-red in SW UV and the Metarossite does not respond. Mike Shannon (pers com May 27, 2022) concurred with the identification of ...
