Deep seismic reflections from the Grenville Front Tectonic Zone.

This seismic cross section gives you a coherent, underground picture of the gigantic thrusting which built the Grenville Orogen. Think of it as a gigantic X-ray (or even better an ultra-sound) picture. The outcrop we just saw is but a tiny sliver within this package of many rock units, which contains many tens of kilometers of cumulative thickness. The tectonic push came from the right of the cross section.
