Mineraliseringen ble første gang anmeldt i 1905, så igjen i 1963 hvorpå den ble undersøkt og beskrevet av Flood (1964 og 1965). Den mineraliserte kvartsgangen befinner seg i en skrent SV for Trolldals- vatnet, 110 m.o.h. Det er sprengt ut noen få m3 som ligger i ura nedenfor. Gangen er blottet over ca. 5 meters lengde. Bredden er ca. 70 cm. Gangen opptrer semikonkordant med foliasjonen i sidestein, som er finkornet grønnliggrå kvartsrik gneis, med bånd rike på hornblende og pyroksen. Nær gangkontakten er noe sulfiddisseminasjon i gneisen (prøve 01). Enkelte mineraliserte apofyser av få cm mektighet skjærer seg noen dm inn i gneisen. Kvartsgangen fører en god del finkornet pyroksen og spor av kalkspat. Dens semimassive - massive sulfidinnhold domineres av magnetkis, noe mindre innhold av kobberkis og sinkblende i omlag like mengder, noe kubanitt, arsenkis, valleriitt, blyglans (?), markasitt, svovelkis, limonitt og molybdenglans (2 korn observert) (prøve 02, 03, 04, 05 og 06). Flood nevner 3 andre mineraliserte ganger i området, hovedsakelig med magnetkis.

A copper-zinc mineralization in Trolldalen, Lofoten, Northern Norway.

Abstract:
From the previous it is most likely that even separated the various mineralizations in Trolldalen are related and contemporary. Allthough different minerals appear in the different veins, pyrrhotite, chalcopyrite and sphalerite are always present. It may also be noted that pyrite, a very common mineral in this paragenesis, is no where observed as a primary constituent. Due to replacement textures the following succession of crystallization is suggested. Appearing as sub. to euhedrale grains, partly replaced by the other sulphides the arsenopyrite seems to be the first mineral in the sequence. It is followed by a simultaneous crystallization of pyrrhotite and chalcopyrite. The pyrrhotite shows two mode of occurrence, as a massive variety with internal lamellae appear at one locality, while a granular type, but for one occasion without lamellae is seen elsewhere. Also a difference in magnetic properties seems to follow this division. The chalcopyrite contain frequent exsolution lamellae of cubanite. The latter appear as granular aggregates in the chalcopyrite fields. It is suggested that the formation of this granular cubanite started from solution formed when the chalcopyrite was corroded by pyrrhotite. Later on both the chalcopyrite and the cubanite have been replaced by pyrrhotite.

Abstract:
Flere mindre mineraliseringer av magnetkis, kobberkis og sinkblende opptrer i fjellet rundt Trolldalsvann. Mineraliseringen er dominert av magnetkis, men forekommstene er for små til at videre undersøkelser kan anbefales.
