This is an analyzed specimen – see the “Analysis” tab. At the qualitative EDS level, it is a good fit for parisite-(Ce). Morphologically it looks more like a “donnayite group” mineral. Possibly it is a pseudomorph. In any case, parisite-(Ce) is rare at MSH. The specimen features dozens of  parisite-(Ce)  “crystals” to about 0.6  mm. There is also a lot of tabular anatase, which MSH is well known for. This specimen features dozens of such crystals to ca 0.3 mm. (You will need 20-40X to view them.)

The first pair of photos (FOV 3.6 x 2.3 mm) shows an isolated anatase crystal 0.25 mm on edge in the center, with many more, some slightly larger, scattered about and inter-grown. The clear catapleiite crystals in the upper right hand corner are about 1 mm in size. Catapleiite and a bit of natrolite are just minor accessories on this specimen.

The second pair of photos (FOV 3.4 x 2.3 mm) shows  more catapleiite and anatase crystals. The largest anatase is < 0.3 mm.

The third pair of photos (FOV 2.3 x 3.4 mm) shows the area richest in the light to dark gray parisite-(Ce). The barrel shaped crystal at right center is 0.5 mm.

The fourth pair of photos (FOV 2.5 x 2.3 mm) shows some of the largest parisite crystals. The one in the center is 0.75 mm tall. Note also the yellow, transparent, tabular (!) siderite crystal on the left. That crystal is 0.5 mm on edge. Behind it are some small, very thin, catapleiite  crystals.

Hand held, the specimen looks like something pulled from the bottom of a charcoal grill.
