Sandstone diagenesis involves porosity loss by mechanical and chemical compaction. In this study we have examined relations of diagenesis
and microstructures in quartz grains and quartz cement in sandstones from relatively deep burial depths offshore mid Norway. Electron backscatter
diffraction analysis (EBSD) has been combined with optical and cathodoluminescence petrography study of samples with different degrees
of compaction and quartz cementation.
