| dc.description.abstract | The Sumozero-Kenozero greenstone belt in the SE Baltic Shield is ∼400 km long and up to 50 km wide and includes two main units with a total thickness of ∼5 km. The lower unit consists of oceanic plateau-type submarine mafic-ultramafic lavas. The upper unit is made up of island arc-type volcanic BADR (basalt-andesite-dacite-rhyolite)-series rocks and adakite-series subvolcanic rhyolites. Both units are separated by major thrust zones from the 3.2 Ga TTG-gneisses of the Vodla Block microcontinent. | |
