A lot going on in a small space here. A layer of calcite is coated by quartz, then yellow spheres of dolomite. On top of this sits a malachite after cuprite crystal aggregate, and then a sprinkling of tiny calcite crystals on the dolomite and malachite. Width of view 11.5mm....

Multiple generations of dolomite. First chocolate-coloured rhombohedra, followed by a much paler (yellow-coated) layer over the same crystals (possibly just a change in chemical composition), with a final white opaque crust here and there. Also, some managnese dendrites bottom right of the photo. Ex John and Betty Weir. Width of...

Labelled “Rum Jungle Copper Mine”. Drill core segment 48mm in diameter from the 1960s. Dolomite crystals in a cavity. The Coomalie dolomite/magnesite dolostone is Precambrian and includes vuggy recrystallised zones (from metamorphic recrystallisation), and formed from stromatolites. It underlies some of the Rum Jungle mines. Click on the image below...

Genie of the lamp. Colourless bladed dolomite crystals over pale blue mcguinnessite on native copper. Height of view 11mm. Stack of 160 images.
Pale greenish marshite(!) crystal with dark cuprite crystals and white dolomite. The marshite fluoresces strongly red with Convoy UV torch. There are three other areas of the specimen that also fluoresce bright red, but individual crystals are hidden. No doubt about the locality, it is typical of Mutooroo. Width 7.5mm....
Zoned yellow and brown sphalerite crystals with colourless rhombs of dolomite and colourless round groups of quartz crystals. A couple of very pale yellow sphalerite crystals exhibit an unusual pinkish fluorescence. Width 9mm. Stack of 120 images.
Ex Barry Johnson Collection. Video best viewed full screen.
Grey complex dolomite crystals with a single brownish cerussite crystal from the Kintore open cut, Broken Hill. In addition, there are tufts of an unknown white mineral. Candidates could be sepiolite (not recorded at Broken Hill) or palygorskite (recorded, but as a different habit, and rare). Maybe something else. It...
