In the fields near an old roadside quarry, one can find many orthoclase crystals.
The matrix (Rostrenen granite) is locally altered.
It is also possible to find pegmatite bits with black tourmaline and green apatite.
Lukas (1978) mentions an "enormous orthoclase deposit, easily exploitable and of exceptional quality (12% potassium) discovered near Plélauff at 'Kerbrien-an-Nivit' (sic), containing over 400,000 tons of pure potassium feldspar." [Kerbrien is located a bit further southeast, near and part of Lescouët-Gouarec].
