The variation of bedrock quality with increasing ductile deformation
Abstract Most of the rocks in Precambrian shield areas have experienced a complex structural and metamorphic evolution, processes which have a strong influence on the bedrock quality. This may vary both on a local and regional scale. The main object of this investigation was to study the variation of the rock mechanical properties at various stages of ductile deformation of an originally isotropic rock. Ten samples from five different localities northeast of Lake Vänern (south central Sweden) were tested, including studded tyre and LA tests, uniaxial compressive strength (UCS), ultrasonic velocity, electrical resistivity, Swedish impact value and Swedish flakiness index as well as petrographic and chemical analyses. This study highlights the importance of considering all possible variations in bedrock before classification, and of undertaking regional investigations.
