Chemical composition of Late Svecofennian granite in the Bothnian Basin, central Sweden
Late Svecofennian granite is frequent in the Bothnian Basin, especially in zones of rapidly changing metamorphic grade but also in areas, where the metamorphic grade is elevated. The granite is essentially undeformed, but weakly foliated or lineated rocks are common; more rarely are rocks strongly foliated. X-ray fluorescence was used for major-element and ICP-MS for trace-element analyses. The ch
