Nordic Research Board
Network on Impact Research (NIR)
is offering a research training course to take place in Sweden, May/June 2007

HOW IMPACT CRATERING AFFECTS LOCAL GEOLOGY, GEOCHEMISTRY, AND GEOPHYSICS
Rättvik, Sweden, May 28. – June 2., 2007

Background
THE SILJAN RING is the second largest of Europe’s recognized impact structures. It is a 50 km wide annular depression consisting of Lower Palaeozoic sedimentary rocks, downfaulted into crystalline basement. The upper levels of the crater have been removed by erosion. The remaining horizontal section gives unusual insight into the deep structure of a major impact crater. We will compare it with other impact structures. In the course we will discuss how modeling of the impact processes helps to understand the resulting geology, and we will also in detail study geochemical and geophysical diagnostic properties of impact craters.

The oldest bedrock is Proterozoic volcanics (yellow, to the E). It is intruded by Proterozoic granite (dark red, to the NE also light red) that is overlain by  later Proterozoic ('Jotnian') volcanics and sandstone (light green, orange, and light red in the NW sector). Blue marks the Lower Paleozoic of the remnant of  the eroded Terrace Terrain that surrounds the Central Uplift. The Uplift consists of Proterozoic granite and, to the NW, volcanics and sandstone.
