Structural and magmatic evolution in the Loimaa area, southwestern Finland

Abstract

Within the Loimaa area there is a junction of the general E-W structural trend of southern Finland and a NW-N-NE curving trend. The structure of the area is dominated by ductile D, and D 4 deformations with E-W and N-S axial traces, respectively. The typical semicircular structures in the study area are interpreted as F,-F 4 fold interference structures.
