Alfredton is a suburb on the western side of Ballarat. In June 2013, a new housing subdivision was under development on the western side of Learmonth Street. Excavation had unearthed quite a lot of fresh basalt which had been gathered in piles around the subdivision. It is likely that this basalt will be crushed for road surfacing. In early June, Toby Billing stopped off to inspect the basalt and found mineralisation. He and Steve Sorrell subsequently visited the site and found a number of mineral species in vesicles.
Most have so far only been identified visually, although a number have been id'd by Peter Elliot using SEM. There are a number that are yet to be identified/confirmed. The list of minerals has been updated/amended based on the feedback from Peter.
The basalt is no longer accessible.

Standard Detailed Gallery Strunz Chemical ElementsDetailed Mineral List:
| ⓘ Aegirine ? Formula: NaFe3+Si2O6 Description: SEM indicates that green "aegirine" has much more Ca than Na so if it is a pyroxene it is probably hedenbergite (Peter Elliot pers comm). References: |
| ⓘ Albite Formula: Na(AlSi3O8) Description: SEM indicates that this mineral has about equal sodium and potassium so is likely albite-orthoclase or andesine-anorthoclase (Peter Elliot, pers comm). References: |
| ⓘ Albite var. Andesine Formula: (Na,Ca)[Al(Si,Al)Si2O8] Description: SEM indicates that this mineral has about equal sodium and potassium so is likely albite-orthoclase or andesine-anorthoclase (Peter Elliot, pers comm). References: |
| ⓘ 'Apatite' Formula: Ca5(PO4)3(Cl/F/OH) Description: Occurs as white acicular crystals. References: |
| ⓘ Aragonite Formula: CaCO3 References: |
| ⓘ Augite Formula: (CaxMgyFez)(Mgy1Fez1)Si2O6 References: |
| ⓘ Dolomite Formula: CaMg(CO3)2 References: |
| ⓘ Fayalite Formula: Fe2+2SiO4 References: |
| ⓘ Hedenbergite ? Formula: CaFe2+Si2O6 Description: SEM indicates that green "aegirine" has much more Ca than Na so if it is a pyroxene it is probably hedenbergite (Peter Elliot pers comm). References: |
| ⓘ Ilmenite Formula: Fe2+TiO3 Description: Specimens visually id'd as hematite have been tested by Peter Elliot and are ilmenite. References: |
| ⓘ Magnesite ? Formula: MgCO3 Description: "Magnesite" submitted for analysis was shown to be dolomite, so magnesite is unconfirmed. References: |
| ⓘ Opal Formula: SiO2 · nH2O References: |
| ⓘ Opal var. Opal-AN Formula: SiO2 · nH2O References: |
| ⓘ Tridymite Formula: SiO2 References: |
