A summary of the petrography and geochemistry of the Bindal Batholith
(NGU-Rapport (92.111), Report, 1994)The Bindal Batholith is a composite intrusive complex which was emplaced into mediumgrade supracrustal rocks of the Helgeland Nappe Complex. The plutonism postdated the internal amalgamation of the Helgeland Nappe Complex, ... -
Distribution of Fe-Ti oxide minerals in the Ørsland, Bakka-Krune and Einebakka area of the Bjerkreim-Sokndal layered norite, Rogaland
(NGU-Rapport (96.130), Report, 1996)Geological mapping in scale 1:5000 in the Sokndal Lobe of the Bjerkreim-Sokndal layered norite intrusion has confirmed that cyclic unit no.IV of the magmatic stratigraphy comprise a high density of Fe-Ti oxide rich layers. ... -

(NGU-Rapport (96.159), Report, 1996)The current report summarize the results of the 1996 field work in the south Rogaland igneous province regarding Fe-Ti deposits. Prospects and mines in the Sokndal area were visited and sampled in a continued effort to ... -
Geologiske undersøkingar på Frøya og Froøyane.
(NGU-Rapport (90.073), Report, 1990)Kartlegging på Frøya og Froøyane har vist at berggrunnen for det meste er samansatt av kaledonske intrusivar som i nokre område innheld xenolittar av metasedimentere bergarter med ukjend alder. På Frøya og i ein del område ... -
Geology and petrochemistry of the Smøla-Hitra Batholith, Central Norway.
(NGU Bulletin (416), Journal article, 1989)The plutonic rocks which compose the Smøla-Hitra Batholith (SHB) cover an exposed area of c.1000 km\u00B2 and intrude folded, Arenig-Llanvirn, low-grade meta-sedimentary and bimodal metavolcanic rocks and higher-grade ... -
