Investigation of post-svecofennian brittle structures in Satakunta. Field report 2009; Post-Svekofennisten kivien hauraiden rakenteiden tutkimus Satakunnassa. Kenttaetyoet kesaellae 2009

Abstract

This report describes the field work in the summer 2009. The task is a part of research entity in which the development of brittle structures in bedrock are acquired. In focus have been the post-Svecofennian rocks of the Satakunta area: rapakivi, sandstone and olivine diabase. We describe the observation methods and the research methods using three target examples: olivine diabase in Pori, Kallo, sandstone in Nakkila, Leistilaenjaervi and rapakivi in the centre of Lappi. We have concentrated on geometry and kinematics of joints in bedrock. Concerning every target we describe the joints and the faults, their orientations and properties, joint fabrics and jointing structures. Our aim is to define orientations of palaeostresses and evolution of brittle structures exploiting joint properties. The study will be continued in Satakunta based on the data collected in the summer 2009 and in a few earlier years. The results can be benefitted also in studies of the Svecofennian brittle structures. (orig.)
