Location No. 11

Roadcut along the main road about 1 km south of Gunnebo.

R: 1543600 - H: 6398900

Keywords: pegmatite vein


Description:

According to Wolffersdorff (1999), the pegmatite vein is 50 to 60 cm thick and cuts through the quartzitic metasediments of the Västervik Formation with a NW-SE strike and a dip angle of 65°. It is in sharp contact with the wall rock. The pegmatite is light in color, medium- to coarse-grained and displays a distinct zoning. The main components are K-feldspars with hypidiomorphic fabric. Quartz occurs only in minor contents and biotite accumulated in nests. The grain size increases from the marginal to the center zones. As Wolffersdorff (1999) described in his studies the pegmatite veins in this area do not show a preferred orientation, but all are steeply inclined.
