"The Harcourt Quarries are situated on the side of Mt. Alexander and have been the most important source of 'granitic' (granodiorite) building stone in Victoria since 1860. Rare druses or vughs containing "stilbite" (actually stellerite) and apophyllite (now fluorapophyllite-(K)) were described from the quarries in 1894."
The minerals described from this locality are based on 2 specimens from the collections of the National Museum of Victoria.

Standard Detailed Gallery Strunz Chemical ElementsDetailed Mineral List:
| ⓘ Babingtonite Formula: Ca2(Fe,Mn)FeSi5O14(OH) Description: "The babingtonite occurs as an elongated black crystalline aggregate, 2 cm by 3 mm in cross-section, enclosed partly by stilbite and partly by apophyllite. In addition, many small single crystals, up to 5 mm long, are enclosed in stilbite or apophyllite, or project into a small irregular cavity which has been etched from the apophyllite. The babingtonite crystals are glossy black, crushing to a dark greyish green. They tend to be slightly tabular and may show coffin-shaped longitudinal sections. Faces in the plane of flattening may be striated." |
| ⓘ Calcite Formula: CaCO3 Description: "A few irregular patches of white calcite occur in the aggregate, as well as within the altered apophyllite." |
| ⓘ Fluorapophyllite-(K) Formula: KCa4(Si8O20)(F,OH) · 8H2O Description: "The pearly, white apophyllite mineral forms irregular patches up to 2 or 3 cm across in the aggregate. The material bordering the etched cavity is quite pulverulent but tends to become harder at the margin of the aggregate where it is in contact with granodiorite." |
| ⓘ Stellerite Formula: Ca4(Si28Al8)O72 · 28H2O Description: "Colourless to pale pink, translucent, bladed stellerite, without crystal terminations filled 90% of the aggregate in which the babingtonite occurs." |
| ⓘ ' Formula: M6-7[Al8-9Si27-28O72] · nH2O Description: Proven to be stellerite |
| ⓘ Titanite Formula: CaTi(SiO4)O Description: "A number of small groups of elongated, wedge-shaped titanate crystals, up to about 1 mm long, occur intimately associated with the babingtonite. They are transparent and pleochroic from nearly colourless to pale brown." |
