Mineraliseringen er blottet i veiskjæring, er av samme type som på Hauknestind og opptrer i de samme bergarter i synklinalkjernen. Synformen stuper ned mot øst ved Hauknestind og kommer opp igjen nord for Andfiskvatn. Ved UTM 462570 7350350 er det en 3 m mektig kalkspatmarmor med kalkholdig glimmerskifer i heng og ligg. Over ca. 0.5 m mektighet mot hengkontakten til glimmerskiferen er marmoren mineralisert med sinkblende, blyglans, kobberkis og svovelkis (prøve 01 og 02). Det er uregelmessige, massive, smale bånd, årer og linser med sulfider. Langs hengkontakten til glimmerskiferen er det en ca. 5 cm sone av kalkspat-tremolitt-glimmerskifer med litt svovelkis-disseminasjon (03). Den kalkholdige glimmerskiferen i hengen er rusten og inneholder litt svovelkis (04). Ved UTM 462730 7350410 er glimmerskiferen i marmorens ligg impregnert med litt kobberkis og svovelkis (05). Foliasjonen er her 205/10. |
