| Dating of the seismic reflectors in our dataset is hampered by the lack of accurately dated successions in deep boreholes in the region. |
| Commercial seismic sections from the North Sea do not image intra-basement reflectors very well. |
| The Base Balder Formation unconformity forms a highly undulating, structured seismic reflector. |
| Situated in a sensitive seismic zone, the country has been rocked by many earthquakes. |
| It also became apparent that the ridges are prime sites of seismic activity and basaltic eruption. |
| Subhorizontal seismic reflectors interpreted as sills are present over a huge region in the basement underlying the Western Canada Basin. |
