Found in 1994. The aggregate looks somewhat like a mckelveyite group mineral, but the crystals are actually platy - like a phyllosilicate. (Of course, some mckelveyite group minerals can form stacked platy aggregates as well, but no Y was detected in the recent SEM-EDS probes by Joy Desor). See some of the child photos. \"Quick & dirty\" SEM-EDS done in May 2017 suggested kellyite, but kellyite is such a rare mineral, not only world-wide, but also at MSH, where it \"typically\" does not look like this, that in the absence of SEM-WDS and\u002For XRD, I was reluctant to post it. Recently (June & July 2021), Joy Desor has done more refined SEM-EDS, Raman, and XRD and the conclusion is that it really is kellyite. I have posted much of this data as analyitical images - which see. (The Raman scan was not very good. But neither was the reference. According to Joy, that's not unexpected with this group of minerals. So rather than muddy the matters, I have chosen not to post that data.) This material was found in 1994, on one of my first trips to MSH. Was there more? I don't know. At that point, I couldn't tell one MSH mineral from another.

Analyzed find. MOB coll. Stereo pair. Judging from the scarcity of Mindat posts for this mineral, it appears to be very rare. Hence, even though this photo isn’t very good - it barely works even in stereo – it may be worth posting. This is the best I can do with my set-up. The xls are just very tiny. To the naked eye (through the scope), the xls appear prismatic and hexagonal. That may seem surprising for a serpentine group mineral, but Tony Steede did EDS and Malcolm Back did XRD confirming kellyite. (This find is described in a copy of a page from a CMMA Micronews Bulletin which I have dated as March 2006. However, there is no date on the article itself and I am unable to find the actual bulletin.) The xls appear to be not quite colorless – but more yellowish than the brownish shade in the photo. (At this magnification, I get a great deal of chromatic aberration and have to resort to brute force to get rid of it. That’s not always possible without affecting the color of the material of interest.) The very small size of the specimen precludes determination of the environment. The only other recognizable mineral is natrolite. Tony mentions sphalerite, aegirine and ancylite.
