Approach outcrop via road Gunnebo Västrum, before entering Västrum take the small road on
the right-hand side to Björnhuvud. Short walk to the southern bay of Björnhuvud.
This sedimentary dike has a thickness of 5 cm and is quite similar to the one at location no. 06, but
here one walks across the polished rocks and can trace the dike for several meters. The host rock is a coarse-grained
granite which, according to Gavelin (1984), probably belongs to the younger granitoids. The sedimentary dike
is steeply dipping and strikes NE-SW. According to Frei (1997), the green colored matrix mainly consists of
rounded quartz grains and chlorite, angular shaped feldspar. Muscovite occur in minor amounts. Granitic fragments,
probably from the host rock, can also be observed.
