Mesoproterozoic Strike-Slip Faulting within the Åland Rapakivi Batholith, Southwestern Finland
TektonikaPaleostress inversion analysis of outcrop data from brittle fault structures within the Mesoproterozoic 1.58 Ga Åland rapakivi granite, southwestern Finland, revealed two separate strike-slip faulting stages. Stage 1 is dominated by dextral slip along E–
