Detailed Mineral List:

ⓘ Albite
Formula: Na(AlSi3O8)
Habit: prismatic
Colour: white
ⓘ 'Apophyllite Group'
Formula: AB4[Si8O20]X · 8H2O
ⓘ Beryl
Formula: Be3Al2(Si6O18)
Habit: elongated prismatic
Colour: colourless to pale blue
Description: Crystals less than 5mm in length, commonly etched
ⓘ Calcite
Formula: CaCO3
Habit: masses
Colour: pale yellow-brown
Fluorescence: orange (SW & LW UV)
ⓘ Chabazite-Ca
Formula: (Ca,K2,Na2)2[Al2Si4O12]2 · 12H2O
Habit: blocky rhombs up to 1.5mm on edge; intergrown masses with the other zeolite group minerals heulandite and stilbite
Colour: colourless
ⓘ Chamosite
Formula: Fe2+5Al(AlSi3O10)(OH)8
Habit: platy hexagonal
ⓘ 'Chlorite Group'
Habit: crystalline masses with a crudely hexagonal form
Colour: dark green to black
ⓘ Danalite
Formula: Be3Fe2+4(SiO4)3S
Habit: tetrahedral to pseudo-octahedral
Colour: pale brown
Description: Green et al. (2005): "Danalite occurs rarely as small translucent brown crystals and grains on joint planes and in small cavities with quartz, saponite and stilbite-Ca. It is later in the paragenesis than all of the other silicate species except the low temperature zeolite group minerals."
ⓘ Fluorite
Formula: CaF2
Habit: octahedra up to 10mm on edge
Colour: colourless, pale green, pale purple, occasionally colour-zoned
ⓘ 'Gadolinite'
Description: Green et al. (2005): "Perhaps the most intriguing reference [to the unnamed and currently disused quarry] is due to the great French mineralogist Lacroix (1888), who reported the discovery of a small crystal of gadolinite on the basis of microchemical tests and optical goniometry."
ⓘ Heulandite-Ca
Formula: (Ca,Na)5(Si27Al9)O72 · 26H2O
Habit: blocky wedge-shaped
Description: crystals up to 2mm with perfect one-directional cleavage
ⓘ Laumontite
Formula: CaAl2Si4O12 · 4H2O
ⓘ 'Mica Group'
Habit: crystalline masses
Colour: dark green
Description: Green et al. (2005): "It has not been possible to identify the mica present to species level as members of the group have very similar XRD patterns."
ⓘ Monazite-(Ce)
Formula: Ce(PO4)
Habit: euhedral blocky to prismatic
Colour: honey-brown
Description: Crystals up to 0.5mm long
ⓘ Opal
Formula: SiO2 · nH2O
Colour: pearly and iridescent
Description: Green et al. (2005): "Greg and Lettsom (1858) claimed pearly and iridescent opal from "Quarus south of Newcastle". It seems possible that "Quarus" could be a misspelling since no such place is marked on modern maps."
ⓘ Orthoclase
Formula: K(AlSi3O8)
Habit: blocky
Colour: creamy white
ⓘ Quartz
Formula: SiO2
ⓘ Quartz var. Smoky Quartz
Formula: SiO2
Habit: short-prismatic
Description: Typically up to a few millimetres long, but exceptionally to several centimetres
ⓘ Saponite
Formula: Ca0.25(Mg,Fe)3((Si,Al)4O10)(OH)2 · nH2O
Habit: amorphous-looking waxy masses
Colour: yellow
ⓘ 'Scapolite'
ⓘ Siderophyllite
Formula: KFe2+2Al(Al2Si2O10)(OH)2
ⓘ Stilbite-Ca
Formula: NaCa4(Si27Al9)O72 · 28H2O
Habit: (aggregates of) flat-topped prismatic to tabular crystals
Colour: colourless to pale brown
ⓘ 'Stilbite Subgroup'
Formula: M6-7[Al8-9Si27-28O72] · nH2O
ⓘ Topaz
Formula: Al2(SiO4)(F,OH)2
ⓘ Vermiculite
Formula: Mg0.7(Mg,Fe,Al)6(Si,Al)8O20(OH)4 · 8H2O
Description: Green et al. (2005): "Stilbite, fluorite and a vermiculite-type mineral were recorded from the "old quarry" by Richey (1927) and the latter mineral was also noted at the "new quarry".
