TL;DR: In this paper, the Rogaland anorthosites are associated with weakness zones in the crust which may have favored their emplacement at mid-crust levels, and it has been shown that the parent magma compositions of various anorthosite massifs lie on thermal high in relevant phase diagrams at 10-13 kbar, indicating that these magmas cannot be derived by fractionation of peridotitic mantle melts but by melting of gabbronoritic sources in the lower crust at 40-50 km depths.

TL;DR: In this article, two magmatic suites were emplaced during the post-collisional evolution of the Sveconorwegian orogeny: an Anorthosite-Mangerite-Charnockite suite (AMC suite) and an hornblende-and biotite-bearing granitoids suite (HBG suite).

TL;DR: In this article, plagioclase and high-alumina orthopyroxene megacrysts from the late Proterozoic Egersund^Ogna massif-type anorthosite were used to constrain the parental magma compositions and differentiation processes within this 30 km diameter diapir.

TL;DR: In this paper, the origin of igneous Fe-Ti oxide ores associated with massif-type anorthosites is investigated through a detailed study of the world-class Tellnes ilmenite deposit, part of the late-Proterozoic AMC series of the Rogaland Anorthosite Province (SW Norway).

TL;DR: In the Rogaland granulites of Southern Norway, thin anhydrous pyroxene-bearing margins (5-10 mm) are observed mainly in migmatitic banded gneisses at the contact between hornblende-rich metabasites and charnockites as mentioned in this paper.
