Depth to bedrock and bedrock morphology from gravity measurements at Stryn, Stryn Municipality, Sogn og Fjordane

Abstract

This report presents geophysical interpretation of gravity data as part of a project whose main objective is to supplement the mapping of Quaternary geology at Stryn. This is achieved through the extraction of depth to bedrock information with the use of gravity data which in turn yields soil thickness and bedrock morphology maps. The gravity method is one of the best techniques when large sediment thickness estimation is required due to its low cost compared to other methods and it can be easily implemented in both rural and urban areas. Our study area is just east of the town of Stryn and farther up the Stryneelva valley.
