| To grunne skjerp (1 m dype) med areal på opptil 4 m2 ligger i kanten av en slette på østsiden av en liten haug og ca. 500 m SØ for Snelitjørna. Mineraliseringen er knyttet til et sett av parallelle kvartsganger 1-20 cm brede og opptil 10 m lange) som dels opptrer stjert om stjert ("en echelon"). Gangenes strøk varierer mellom N59-92Ø, og de faller steilt (60-80°) mot S og SØ. De gjennomsetter kalksilikatbåndet kalkspatmarmor med str./fall: 219/40. Sulfidmineraliseringen langs gangene er meget svak og omfatter spredte korn og aggregater av blyglans og sporadisk arsenkis samt sprekkefyllinger av blyglans langs gangkontakten. |

| Abstract: | |
| The principal geological and tectonostratigraphic divisions of the bedrock within the area of mapsheet Mosjøen are: (1) Precambrian basement rocks with minor occurrences of possible Cambrian cover sediments, (2) the Susendalen Nappe, (3) the Seve-Køli Nappe Complex, (4) the Rødingsfjell Nappe, and (5) the Helgeland Nappe Complex. Short accounts of economic geology (ores and industrial minerals) are given. |
