Mineral Spot: NZ Stilbite...

Got back from New Zealand yesterday. The ten days went fast. Took lots of photos, some of which I will share over the coming days.

I brought back a selection of mineral specimens and this is one of them. It is a stilbite crystal from Waitakauri, not far from where we were for the Symposium and Seminar. The field of view is 9mm.

Mineral Spot: Ferrierite...

In a few days time, I will be heading over to New Zealand for the 30th annual Joint Mineralogical Societies of Australia Seminar which is being held in conjunction with the New Zealand Micromount Symposium at Waihi, on the North Island.

The theme for the Seminar is Volcanic Minerals and Mineralogy. In keeping with this theme, I have included an image of an uncommon zeolite mineral, ferrierite, that occurs in basalts on Phillip Island in Victoria. I'm not sure which series member this is, possibly ferrierite-Mg. It occurs as silky-white fibres or acicular crystals in cavities in the basalt.

Spring is well and truly with us and this little bug was making the most of the early morning sunshine today...

Mineral Spot: Wulfenite...

I really enjoy collecting micro minerals.

A good definition of a micro mineral is a specimen that requires illumination and magnification to be appreciated. It is possible to put together a good collection, without too much expense (microscope purchase aside). Crystals can be more perfect than on larger specimens, and in many cases, rare minerals only occur in small sizes. And your whole collection can be housed in a relatively small space.

Because of their small size, it is not difficult to build up a collection of trading material. This can be used to swap with other collectors around the world. I recently received a small exchange package from a friend of mine, Mark Ascher of Tucson, Arizona. One of the specimens he sent is this unusual blocky wulfenite from the Fulton Mine in Pima County, Arizona.

Did I ever say how much I really enjoy collecting micro minerals?
