The Precambrian basement on northern and eastern Bornholm consists of different types of granitic and gneissic rocks with pegmatites, aplites and dolerite dykes (Callisen 1934). The age of the granite and gneiss is <em>c.</em> 1455 Ma (Waight <em>et al.</em> 2012).</p>}, journal={GEUS Bulletin}, author={Gravesen, Peter and Jakobsen, Rasmus and Nilsson, Bertel}, year={2015}, month={Jul.}, pages={33–36} }
