摘要

Rogaland Anorthosite省（RAP）是暴露在挪威南部Sveconorwegian造山带中的典型元古代Anorthorite–Mangerite–Charnokite（AMC）深成岩体复合体，在约933–916 Ma沿剪切带底辟侵彻地壳。剪切带最近被定义为Farsund剪切带（FSZ），沿斜长岩省的东侧突出，它由强烈的叶理、陡倾、带状片麻岩组成。带状片麻岩包括多种岩性：变质基岩、花岗质片麻岩、眼球状片麻岩和金字状片麻岩。主要来自带状片麻岩的样品的主要元素和微量元素组成

The Farsund Shear Zone: geochemical evidence for lithological diversity in the wall rock of the Rogaland Anorthosite Province, South Norway

The Rogaland Anorthosite Province (RAP) – a typical Proterozoic Anorthosite–Mangerite– Charnockite (AMC) plutonic complex exposed in the Sveconorwegian orogen in South Norway – was emplaced diapirically through the crust, along a shear zone, at c. 933–916 Ma. The shear zone, recently defined as the Farsund Shear Zone (FSZ), crops out along the eastern flank of the anorthosite province, and it is made up of strongly foliated, steeply dipping, banded gneisses. The banded gneisses comprise a diversity of lithologies: metabasites, granitoid gneisses, augen gneisses and kinzigitic gneisses. Major and trace element compositions of samples mostly from the banded gneisses

期刊介绍： The Norwegian Journal of Geology publishes high-quality, fully peer-review papers from all geoscientific disciplines. Papers are commonly based on regional studies and should emphasise the development of understanding of fundamental geological processes. More specialised papers can also be submitted, but should be written in a way that is easily understood by nonspecialists, and illustrate the progress being made within that specific topic in geosciences. We also encourage initiatives for thematic issues within the scope of the Journal.
