The Norwegian database of cultural heritage sites lists two Reiersdal localities (see links below): Reiersdalgrua Nedre (ID 231883) at 58.324216129363,7.7956047181995 and Reiersdal Øvre (ID 231886) at 58.322604918126,7.7939312887122.
These quarries were worked in the early 1900s, and are situated south of the Reiersdal farm.
Griffin (1979) describes a locality "above" the Reiersdal farm, and indeed at the Mindat coordinates of 58.3287,7.79701 a quarry can be seen at the LiDAR map.

| ⓘ 'Allanite Group' Formula: (A12+REE3+)(M13+M23+M32+)O[Si2O7][SiO4](OH) |
| ⓘ 'Biotite' Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg/Ti)([Si/Al/Fe]2Si2O10)(OH/F)2 |
| ⓘ 'Britholite Group' Formula: (REE,Ca)5[(Si,P)O4]3X References: |
| ⓘ Britholite-(Y) ? Formula: (Y,Ca)5(SiO4)3OH Description: First described as "Britholite-(Y)" by Griffin et al. The analysis published in their paper however showed that the sample studied had a high content of F (1.18 wt%), thus > 50 apfu and should be a fluorbritholite according to the revision of the nomenclature of the apatite supergroup (Ferraris et al 2010). Britholite-(Y) may occur at the locality but further studies are necessary. |
| ⓘ Calcite Formula: CaCO3 Description: As microsopic inclusions in britholite-(Y). Secondary, formed by alteration along fractures |
| ⓘ Fluorapatite Formula: Ca5(PO4)3F Description: As microsopic inclusions in britholite-(Y). Secondary, formed by alteration along fractures |
| ⓘ Fluorbritholite-(Y) Formula: (Y,Ca)5(SiO4)3F Habit: Occurs as crystals 5-20cm large crystals, metamict amorphous Colour: Light tan to chocolate brown with greasy to adamantine lustre on fracture surfaces Description: First described as "Britholite-(Y)" by Griffin et al. The analysis published in their paper however shoved that the sample studied had a high content of F (1.18 wt%), thus > 50 apfu and should be a fluorbritholite according to the revision of the nomenclature of the apatite supergroup (Ferraris et al 2010). See also type description of fluorbritholite-(Y) (Pekov et al 2011)
Occurs as crystals 5-20cm large crystals, metamict amorphous. Contains microsopic inclusions of several phases (apatite-CaF, tombarthite-(Y), calcite and possible thalenite-(Y) ? ) |
| ⓘ Keiviite-(Y) ? Formula: Y2Si2O7 Description: As microsopic inclusions in britholite-(Y). Secondary, formed by alteration along fractures.
The mineral described as "thalenite" from Reiarsdal is probably Keiviiite-(Y). Griffin et al. (1979) notes that the "thalenite" is identical with the phase beta -Y2Si2O7 mineral with thortveitite structure reported from Høgetveit, Evje and Åskagen, Sweden. |
| ⓘ 'K Feldspar' |
| ⓘ 'Plagioclase' Formula: (Na,Ca)[(Si,Al)AlSi2]O8 |
| ⓘ Quartz Formula: SiO2 |
| ⓘ Thalénite-(Y) ? Formula: Y3Si3O10F Description: As microsopic inclusions in britholite-(Y). Secondary, formed by alteration along fractures.
The Reiarsdal "thalenite" may be = Keiviiite-(Y). Griffin et al. (1979) notes that it is identical with the phase beta -Y2Si2O7 mineral with thortveitite structure reported from Høgetveit, Evje and Åskagen, Sweden |
| ⓘ Titanite Formula: CaTi(SiO4)O |
| ⓘ Titanite var. Yttrium-bearing Titanite Formula: (Ca,Y)TiSiO5 |
| ⓘ ' Formula: Y4(Si,H4)4O12-x(OH)4+2x Colour: black Description: As microscopic inclusions to 2mm in britholite-(Y). Secondary, formed by alteration along fractures. Discredited by IMA 2016. CNMNC Newsletter No. 34: all samples proved to be of heterogeneous nature. |
| ⓘ Uraninite Formula: UO2 |
| ⓘ Zircon Formula: Zr(SiO4) |
| ⓘ Zircon var. Malacon Formula: Zr(SiO4) |
