Carbonate rocks of the Tverrvika area, Beiarn: potential for white calcite marbles, chemistry, isotope geochemistry and age.
;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.99.032;58 s. pages
Abstract:
Marbles at Beiarn are a part of the Sokumfjell Group belonging to the Beiarn Nappe Complex in the Uppermost Allochthon of the Nordland Caledonides. The Sokumfjell Group marbles have been subjected to several phases of deformation culminating with amphibolite facies metamorphism. The 1:5,000 mapping of ca. 1000 m-thick carbonate sequence reveals four different lithofacies of calcite marbles and one composed of diagenetically formed dolomite marble. The calcite marbles exhibit, througout, different scale rhythmic bedding and textural grading indicating that carbonate material was redeposited by pelagic turbidite system. Both proximal and distal facies have been identified. (forkortet)

Kalkstein- og dolomittundersøkelser i Nordland.
;Norges geologiske undersøkelse;FAGRAPPORT;NGU-rapport; No.1118/9;73 pages
Abstract:
Rapporten er sammensatt av åtte delrapporter og gir en samlet oversikt over de kalkstein- og dolomittundersøkelser som NGU har utført i Nordland fylke i 1972. De fleste forekomstene har ingen økonomisk verdi. Det er tynne kalksteinsoner med innblanding av kvarts, gneis og amfibolitt. Følgende forekomster kan være interessante og anbefales videre undersøkt: Noen mindre kalksoner ved Tvervik (Beiarn). Dolomittforekomst ved Larsos (Beiarn). Et mindre område ved Åsåsen (Lurøy) virker interessant. I Helfjeld- bygden (Vefsn) kan videre undersøkelser motiveres. Dolomittpartier i en kalksteinsone ved Lysnehammeren (Skjerstad) bør undersøkes videre. Ved Tovåsen (Leirfjord) ligger den mest interessante kalksteinforekomsten. Den anbefales undersøkt videre. I Granåsen (Vefsn) ligger den mest interessante dolomittforekomsten. Det er en mektig dolomittsone som anbefales undersøkt videre.
