META-ZEUNERITE
Specimen mtz-6

Dims: 1.1 x 1.1 x 0.6" (2.8 x 2.8 x 1.4 cm)

Wt: 19 g w/ specimen box

Majuba Hill Mine, Pershing County, Nevada, U.S.A.

This thumbnail specimen consists of many flattened, intergrown Meta-zeunerite blades that rest on a pale brown base. These blades do not appear to exceed 0.3" (8 mm) in either length or width and are in moderately good condition, showing some damage. Their tetragonal tabular form, green color and micaceous, pearly luster are all quite similar to those of its close relatives, torbernite and meta-torbernite, though its green color is slightly duller. The specimen is affixed inside a plastic thumbnail box with a removable putty.

Majuba Hill Mine, Pershing County, Nevada, U.S.A.

Several tiny Meta-zeunerite tablets rest on the dark brown base of this thumbnail specimen. They are generally in good condition, shnwing little damage, and do not exceed 0.1" (3 mm) in diameter. Though some appear to be intensely intergrown, those that are not show excellent tetragonal tabular form. Their grass-green color and pearly luster are very similar to that of zeunerite, torbernite, and meta-torbernite. It would appear that another secondary copper mineral is present- it is likely olivenite, which is rather commonly found at this locality. The piece is affixed inside a plastic specimen box with a removable putty.

Dims: 2.0 x 1.6 x 1.4" (5.2 x 4.2 x 3.6 cm)

Wt: 2.4 oz. (69 g)

Majuba Hill Mine, Pershing County, Nevada, U.S.A.

Dozens of tiny Meta-zeunerite blades rest on the shale base of this specimen. These blades appear to be in excellent condition and do not exceed 1 mm in diameter. Their tetragonal tabular form, green coloration and pearly luster make these crystals appear very similar to torbernite, though their green color is considerably paler.

Dims: 3.5 x 3.1 x 2.0" (8.8 x 7.9 x 5.0 cm)

Wt: 11.0 oz. (311 g)

Myler Mine, Majuba Hill, Pershing County, Nevada, U.S.A.

Several small Zeunerite crusts partly coat the base of this cabinet piece. These crusts are made up of heavily intergrown Zeunerite tablets that are generally in good condition and do not exceed 0.1" (2-3 mm) in diameter. Their tetragonal tabular form is difficult to define because of their tight intergrowth and the probability that they grew in a tight crevice. All have the standard pale green coloration and pearly luster and are likely translucent and cloudy - the tablets tend to lay flat against the base, so one cannot see light through them.

Dims: 2.6x1.5x1.3" (6.7x3.7x3.4 cm)

Wt: 2.7 oz. (77.2g)

Myler Mine, Majuba Hill, Pershing County, Nevada, USA

This specimen consists of a heavy sprinkling of meta-zeunerite crystals on a multi-colored rock. The meta-zeunerite crystals are very good, showing an excellent sea-foam green color. All are rectangular blades in a variety of orientations. They are opaque, and still have a vitreous luster (dull on most faces, vitreous on the edges). As a radioactive specimen, it should be handled as little as possible, and stored under glass or a plastic dome.

Dims: 2.76x1.35x1.17" (7.00x3.43x2.98cm)

Myler Mine, Majuba Hill, Pershing County, Nevada, USA

This meta-zeunerite has more than a dozen clusters of small green crystals on one surface of a host rock that has at least another half-dozen minerals present. The meta-zeunerite crystals, being rather small and scattered, are at least well-formed and many of them are undamaged. In general, they are thin rectangular plates, although some of them have rounded corners.
