TL;DR: In this paper, U-Pb dating of zircons from the Yxsjoberg and Svardsjo leptites yields a discordia age of 1900 ± 19 Ma and for Zircons, 1873+11 -10 Ma.
Abstract: U-Pb dating of zircons from the Yxsjoberg and Svardsjo leptites yields a discordia age of 1900 ± 19 Ma and for zircons from the synorogenic granite near Svardsjo, 1873+11 -10 Ma. Calculation with the systematics of Wickman (1983: Uranium-lead isotope systematics: The case of crystals with discrete cores. Lithos 16, in press) gives an age of 1925 Ma for the granite zircons.
TL;DR: In this paper, a forward modeling based on an experimental investigation successfully duplicated main features of the gabbros in the Skaergaard layered series, and the experimental techniques and methods were chosen to represent a reasonable approximation to the inferred emplacement and crystallization conditions of the skaergaard intrusion.
