Frøyså 1 feltspatbrudd, Frøyså, Iveland, Agder, Norge
A granite pegmatite quarried for feldspar located about 2 km west of the Frøyså farm. The pegmatite was a 20 m wide irregular body. The outer zones of the pegmatite consisted of "graphic granite" ("Skriftgranitt")- graphic intergrowths of quartz and microcline.
Bjørlykke locality n° 9.

✪ 'Almandine-Spessartine Series' Habit: Dark crystals with high lustre. Size up to minimum 4 cm. The garnets are found in feldspar, smokey quartz and inbetween biotite sheets. The latter ones are normally flattened. Description: Garnets from the nearby Frøyså 3 quarry has been analyzed and found to be a spessartine with a significant almandine content(Larsen 1980). No analysis has been done on garnets from Frøyså 1 |
ⓘ Beryl Formula: Be3Al2(Si6O18) |
ⓘ 'Biotite' Formula: K(Fe2+/Mg)2(Al/Fe3+/Mg/Ti)([Si/Al/Fe]2Si2O10)(OH/F)2 Description: Large sheets > 1 sq.m, but also nicely developed smaller crystals up to minimum 5 cm. |
ⓘ Euxenite-(Y) ? Formula: (Y,Ca,Ce,U,Th)(Nb,Ta,Ti)2O6 Description: Bjørlykke (1934) lists it as "euxenite group" |
ⓘ 'Feldspar Group' |
ⓘ 'Feldspar Group var. Perthite' |
ⓘ Fergusonite-(Y) Formula: YNbO4 References: |
ⓘ 'Gadolinite' |
ⓘ Magnetite Formula: Fe2+Fe3+2O4 Habit: Irregular and poorly developed crystals up to minimum 5 cm. Description: magnetite are frequently found in the border zone of the pegmatite towards the surrounding rock. References: |
ⓘ Microcline Formula: K(AlSi3O8) |
ⓘ Monazite-(Ce) Formula: Ce(PO4) References: |
ⓘ Muscovite Formula: KAl2(AlSi3O10)(OH)2 |
ⓘ 'Plagioclase' Formula: (Na,Ca)[(Si,Al)AlSi2]O8 Description: Relatively common, also as "moonstone". Also graphic granite with "moonstone" plagioclase can be found. This material has a potential as lapidary material |
