This book should be considered as a geological field guide with main focus on the area around Vastervik in southeast Sweden. The Vastervik Area mainly consists of early Proterozoic rocks. Meta-sediments and metavolcanites are intruded by granitoids and dykes, which had caused contact metamorphism and migmatization. 20 locations have been chosen from this area. They present an overview on the different and most common rock types as well as significant structural phenomenon in the Vastervik area. First, the reader gets a brief introduction to the geology of the Baltic Shield. This is re-commendable, especially for participants who are unfamiliar with this topic. A detailed summary describes the geology of the Vastervik Area, followed by the description of the chosen locations. Afterwards one can choose from the suggested field trips or plan an individual tour. This guide is targeted at both geologists, as a basis for their own field education, and non-geologists, as a tour guide for their hobby field trips, alike.
