Formula: (Ca,Fe3+)2Cu5(Bi,Cu)(PO4)4(H2O,OH,Cl)13
Type Locality:
Description: "In April 1995 a boulder was broken open of pegmatite in the quarry, exposing copper mineralisation consisting of massive supergene chalcocite partially altered to a suite of secondary copper and silver minerals, including one containing Ca,Cu,Bi,P and Cl. (Bleasdaleite). The chalcocite in the bleasdaleite-bearing boulder forms massive patches up to about 5 cm across, occupying space between large orthoclase crystals. The rock around these patches is stained green, possibly due to malachite. Thin sections show that much of the chalcocite has been corroded and altered to veinlets of covellite. Secondary minerals have precipitated on the corroded surface of the chalcocite-covelliet. Pseudomalachite and chalcosiderite/turquoise form globules and crusts, while rare ulrichit, libethenite, torbernite and iodargyrite are present as scattered crystals with dimensions less than 1 mm. Bleasdaleite itself occurs as thin, dark brown scaly crusts and hemispherical clusters up to about 0.1 mm across. Scanning electron microscopy reveals delicate tabular crystals forming open rosette-like clusters and linings. The crystals reach up to about 20 micron across but are less than 1 micron thick. The lustre on broken surfaces is resinous, streak pale brown. Thin sections show bleasdaleite crystals are transparent and also reveal a well developed (001) cleavage."

Formula: CuFe3+6(PO4)4(OH)8 · 4H2O
Description: "Pale blue, pale green or bluish green globular crusts and individual spheres or hemispheres of minerals in the composition series between turquoise and chalcosiderite are widespread in the Lake Boga granite quarry. They occur most often lining small miarolitic cavities but may also be found on joint planes and in cavities etched in fluorapatite. Individual globules may reach close to 1 mm across. Well formed crystals have not been observed. Massive partial replacements of orthoclase crystals by turquoise have been collected, but are very rare. As an early-formed secondary hydrothermal mineral, turquoise/chalcosiderite is found with most of the other secondary phosphates from Lake Boga. Microprobe analyses of the bluish green crusts show the compositions fall between ferrian turquoise and aluminan chalcosiderite."

Formula: Ca5(PO4,CO3)3(F,O)
Description: "Attractive well-formed fluorapatite crystals are found in miarolitic cavities, particularly in the upper levels of the quarry. In general, crystals have simple hexagonal to near circular outlines, and range from tabular to blocky and, less often to prismatic. Complex terminations are absent, and crystals usually have a flat lustrous pinacoids face, often showing growth outlines. Some crystals show weakly developed low angle pyramidal faces. The prism faces are almost always striated. The largest crystal collected include tabular varieties 4.5 cm across and 1 cm thick, and prisms 2.5 cm long and 1.2 cm across. Colour in the larger crystals generally ranges from shades of dull greyish to bluish green and deep opaque blue. Most crystals show colour zoning involving these shades, as well as near colourless and pale purple zones. The most common scheme is for pale blue translucent crystals to have dark blue bands at the upper and lower pinacoids. Sparklings of smaller crystals from opaque cream or grey to colourless or transparent blue or mauve are also found. Apatite has also been found rarely at Lake Boga as lustrous, fibrous globular dark green linings to cavities."

Description: "The metanatroautunite forms crystals and clusters up to 4 mm across on limonite-coated joint planes and in miarolitic cavities. Crystals may appear to be aggregates of intergrown plates with slightly rounded edges. In some crystals with more blocky habits, these plates may be separated. The upper surface of these crystals tend to be slightly concave and crinkled partly due to dehydration. Rare intergrowths with saleeite or torbernite occur. Metanatroautunite is initially difficult to distinguish from saleeite at Lake Boga. However, metanatroautunite tends to be translucent with a pearly or slightly greasy lustre, and be bright lemon yellow. This colour may be slightly more intense on the edge than on the upper face. Saleeite at Lake Boga is generally transparent and more golden yellow."

ⓘ Newberyite (TL)
Formula: Mg(PO3OH) · 3H2O
Description: Newberyite crystals from Skipton Caves show 3 different habits 1- the crystals are tabular, translucent to opaque and grey-brown, with faces of the dominant form being uneven and dull. Complex twinning on these faces produces irregular rosettes of intergrown plates or roughly spheroidal shape which may reach 5 cm across. 2- these crystals are glassy, internally fractured, have lustrous faces and range from pale yellow to a dirty brown colour. Inclusions of guano particles are common. These crystals are usually 0.1-10 mm. 3- less common habit shows features with characteristics of the tabular form and equant habits. These form "skeleton" crystals, in reference to the set of partly separated plates developed parallel to the brachy-pinacoids.

✪ Ulrichite (TL)
Formula: CaCu(UO2)(PO4)2 · 4H2O
Type Locality:
Description: "This attractive mineral was first collected at the Lake Boga quarry in the mid-1980s. A zone a few metres across at the base of the east wall of the quarry, at a depth of around 20 metres has yielded all the ulrichite so far collected. Ulrichite forms delicate radiating sprays of translucent to transparent, pale green to bright lime green, needle-like crystals up to 1 mm long and 0.05 mm thick. They occur in small close up, irregular miarolitic cavities in a fine-grained equigranular phase of the Lake Boga granite. Some of the cavities are lined or partly filled with a glistening reddish brown clay mineral. Ulrichite is amongst the earliest of the secondary minerals to crystalise at Lake Boga and occurs most frequently with turquoise/chalcosiderite. It is also observed with cyrilovite, libethenite, pseudomalachite and rarely, with torbernite. It has also been found on etched fluorapatite crystals."
