Description
På Randøy ved gården Randa ligger 5 brudd langsetter tilnærmelsesvis samme bergartssone. Mektigheten er opp mot 4 m i de østlige bruddene. Spalteegenskapene er svært uregelmessige og skliferen er hard og sprø. Opptreden av folder og oppsprekkinger forekommer hyppig. Forekomsten egner seg kun til drift i liten skala. Dette er et av de østligste bruddene.
