Abstract:
During Ocean Drilling Program Legs 152 and 163, we recovered core from the offshore East Greenland volcanic province. The basaltic core recovered included a set of structural elements reflecting the history of extrusion, cooling, postdeposition alteration, and minor tectonism. Brittle features in the basaltic core include faults and several generations of veins. Several minicore samples from the lower sections of core from Hole 917A were taken for paleomagnetic analysis, primarily to test whether there were any significant postdepositional tectonic rotations or whether the core could be reoriented using paleomagnetic techniques. The characteristic magnetization direction was used to estimate the in situ orientation of measured structural features within the core. Although significant uncertainty is associated with the analysis, the corrected attitudes of veins in basalt at Site 917 dip moderately west, with a smaller, conjugate group of veins dipping moderately east-southeast, parallel to other seaward-dipping faults in the area, which were interpreted from seismic lines.
