Other/historical names associated with this locality:
Korghal; Kurghal
The deposits consist of Cs-Rb-Li-Ta-Nb-rich pegmatite veins, embedded in proterozoic crystalline schist and garnet-sillimanite-biotite gneiss (Bariand & Poullen 1978). Individual veins are hundreds of meters long and up to 50 m thick. The Kurghal pegmatite, for which the field is named, was mined for some time around 1995. Among other species, it produced green tourmaline (Orris & Bliss, 2002).
