1.2 Geographical position and landscape
This geological excursion guide with main focus on the area around Västervik in south-east Sweden has been
written as a diploma thesis at the Geoscience Center of the University of Göttingen. Based on approximately
35 diploma maps at a 1:10000 scale, which have been done at the Geoscience Center of the University of Göttingen
since 1994, 20 locations have been chosen from these geologic maps. They present an overview on the different and most
common rock types as well as significant structural phenomenon in the Västervik area.
The field guide is available for the public and is published on the Geoscience Online Community website
This guide is targeted at both geologists and non-geologists alike. Geologists and teachers may use this guide as
a basis for their own field education. A layman may be interested in geology as a hobby.
This guide presents a brief introduction to the geology of the Baltic Shield. This is recommendable, especially
for participants who are unfamiliar with this topic. A detailed summary describes the geology of the Västervik
Area, followed by the description of the chosen locations. Afterwards one can choose from the suggested field trips
or plan an individual tour through the Västervik area.
Due to the complexity of the Precambrian geology every detail may not be found within this guide. To get a
closer look on this topic please take advice on the references and further readings given in every chapter.
The Västervik Area has an areal distribution of about 2000 km2. It is located within the Småland
Province in SE-Sweden on coast of the Baltic Sea around the town of Västervik (cf. fig. 1.1) which lies between the
villages of Falerum in the north and Misterhult in the south.
The landscape mainly has been formed by the last Quaternary glaciation 10000 years ago (Weichselian Glaciation).
One characteristic feature is the sag-and-swell topography. The maximum elevation varies between 25 m at the coast
and 100 m upcountry. The tops of the exposed rocks are often marked with glacial striations, especially at the coast.
Another characteristic feature is the large number of lakes, which often they have an elongated shape with
a main strike direction of NW-SE to NNW-SSE.
The conditions of exposure are often restricted. Many parts of the area are forested and the exposed rocks
are often covered with moss and lichens. For this reason most of the outcrops chosen in this guide are located
at the coast, along road-cuts or in quarries.
