Underneath the volcano: Trying to understand how igneous sills are emplaced using outcrops and seismic from East Greenland
Here I will tell you about our ongoing work to understand sill emplacement, using data from Jameson Land in East Greenland. It is a unique onshore basin, in many ways analogous to the Mid-Norwegian margin, where host-rocks and sills occur in both outcrops AND crustal-scale seismic data. This makes it possible to investigate how igneous intrusions are imaged in seismic data, how lithology influences sill emplacement, and possibly how large-scale tectonic stresses influence geometries of the igneous system.
