Summary

[edit]
Description Thin section of a reddish aplite dike in granodiorite. The sample comes from NE of La Bardinie, Nontron, Dordogne, France. Dark grey quartz stringers within slightly perthitic alkali feldspar. Some of the stringers have quite distinct boundaries following symmetry planes within the host - typical for graphic aka runic textures.
