Influence of mineralogy on polygonal fault formation in the North Viking Graben


Project description
Polygonal faults are present at several stratigraphic levels in the Northern North Sea. Their formation mechanism is generally believed to be shrinkage due to chemical compaction. As a results of this formation mechanism, polygonal faults are confined to specific strata and do not have a preferred orientation. To date, no detailed investigation of the relationship between the shapes and occurrences of polygonal faults and the host rock mineralogy appears to have been documented.

This MSc thesis will address analyses of the mineralogy of polygonally faulted rocks and the relationships between fault characteristics and mineralogy. The resulting observations will be used to refine the existing models for polygonal fault formation.
