U–Pb zircon ages of Permian magmatism in the Vestfold lava plateau and Ramnes caldera, Oslo Graben
Year: 2024
Type: article
Abstract: The Vestfold lava plateau, in the southern segment of the Oslo Graben, is composed of some 200 members (flow complexes) of rhomb porphyry, basalt and trachyte, with a combined estimated thickness of ca. 3 km. Three trachytes dated using the zircon U–Pb method yield ages of 286.8 ± 0.6 Ma for trachyte T1, 282.2 ± […]
