Mineraliseringen har utgående i et stup, og er derfor vanskelig tilgjengelig. Det er utbrudt omkring 5 m3. Over kalkspatmarmor er det minst 5-6 m mektig, rusten granatglimmerskifer med tynne lag av amfibolitt (± granat). Det er litt diss. av magnetkis og svovelkis og spor av kobberkis over hele mektigheten av glimmerskifer (prøve 03) og amfibolitt, men sulfidene er konsentrert i minst ett 20-30 cm mektig lag av semimassiv magnetkis og litt svovelkis i grafittglimmerskifer (01, 02 og 04) med noe cummingtonitt. I den mineraliserte sonen er det lokale diskordanser pga. glidning. |
