Abstract

Sweden has thousands of caves cut into the bedrock, two thirds of which occur in the crystalline bedrock, and hence represent pseudokarst phenomena. The formation of these caves can only be understood in terms of paleoseismics. In this paper, we review the parallel evolution of the concept of pseudokarst caves and of the concept of paleoseismic activity in Sweden, and combine both concepts into a unified theory on the formation of fractures, fracture caves and angular block heaps.
