Economic potential of potassic feldpar-rich gneisses in Tysfjord/ Hamarøy, northern Norway
Potassic feldspar gneiss in the Tysfjord\/Hamarøy area may be potential resource for future exploitation. The rock consists primarily of microcline (up to 84%) and quartz (up to 35%) together with small amounts of plagioclase (1-12%), commonly albite. Accessory minerals include epidote, micas and ma...
