TLDR
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).Citations

The boring billion? – Lid tectonics, continental growth and environmental change associated with the Columbia supercontinent
TL;DR: The supercontinent cycle posits that the continental crust is periodically amalgamated into a single landmass, subsequently breaking up and dispersing into various continental fragments as mentioned in this paper, and the evolution of Earth's biosphere, atmosphere and hydrosphere is tied to the formation of continental crust and its subsequent movements on tectonic plates.

A non‐collisional, accretionary Sveconorwegian orogen
Trond Slagstad,Nick M.W. Roberts,Nick M.W. Roberts,Mogens Marker,Torkil S. Røhr,Henrik Schiellerup +5 more
TL;DR: The late Mesoproterozoic Sveconorwegian orogen in southwest Baltica is traditionally interpreted as the eastward continuation of the Grenville orogen, resulting from collision with Amazonia, forming a central part in the assembly of the Rodinia supercontinent as mentioned in this paper.

Continental growth and reworking on the edge of the Columbia and Rodinia supercontinents; 1.86–0.9 Ga accretionary orogeny in southwest Fennoscandia
Nick M.W. Roberts,Trond Slagstad +1 more
TL;DR: In this paper, a synopsis of the geological evolution of southwest Fennoscandia during the ca. 1.9-0.9 Ga period is presented, with three major periods of continental growth defined by the Transscandinavian Igneous Belt (1.86-1.66, Ga), Gothian and Telemarkian domains.

Crustal evolution and the temporality of anorthosites
Lewis D. Ashwal,Grant M. Bybee +1 more
TL;DR: In this paper, the authors characterize three different types of temporally restricted anorthosites, and discuss their significance to the broad-scale evolution of planetary processes, and suggest that the earliest planetary crust-forming processes on the Moon, and possibly elsewhere, involved substantial, if not total melting.

Subcommission on geochronology: Convention on the use of decay constants in geo- and cosmochronology
R.H. Steiger,E. Jäger +1 more
TL;DR: The IUGS Subcommission on Geochronology (FOOTNOTE 4) as discussed by the authors recommended the adoption of a standard set of decay constants and isotopic abundances in isotope geology.

M. Wiedenbeck,P. Allé,Fernando Corfu,William L. Griffin,M. Meier,F. Oberli,A. von Quadt,J.C. Roddick,W. Spiegel +8 more
TL;DR: In this paper, the results of a study to develop natural zircon geochemical standards for calibrating the U-(Th)-Pb geochronometer and Hf isotopic analyses are reported.

A-type granites: geochemical characteristics, discrimination and petrogenesis
TL;DR: A-type granites as mentioned in this paper were found to have high SiO2, Na2O+K2O, Fe/Mg, Ga/Al, Zr, Nb, Ga, Y and Ce, and low CaO and Sr.

TL;DR: The roots of isotope geology can be found in this paper, where a geology of Neodymium and Strontium in meteorites and Igneous rocks is described.
