Description |
Fra Grenne (1983): En vasskishorisont som kan følges 350 m langs strøket i elvedalen til Mosbrunnskjerva. I SV er det en 0.5-1 m mektig massiv og kompakt vasskis med stort sett svært finkornet pyritt. Mot NE blir magnetkis dominerende med underordnet pyritt og spor av kobberkis. Her er vasskisenheten bare 20-30 cm mektig og har dels en diffus bånding. |
