P-T evolution of paragneisses and amphibolites from Romeleåsen, Scania, southernmost Sweden
Populärvetenskaplig sammanfattning Vad har berget i Romeleåsen varit med om? Jordskorpan är uppbyggd av ett antal plattor. Vid plattgränser under oceanerna bildas ny skorpa av magma som tränger upp. Oceanplattan kan inte öka i storlek. Där oceanplattan möter en platta med kontinental jordskorpa tränger oceanplattan under kontinentalplattan (subduktion, t. ex. Anderna).

Fennoscandia forms a part of the East European Craton and was extended to the south-west during prolonged episodes of accretion during the period 1.95-1.55 Ga. Metamorphic reworking took at least place during the Hallandian/Danopolonian orogeny at 1.47-1.38 Ga and during the Sveconorwegian orogeny 1.10-0.92 Ga. Hig
