Silurian in Notre Dame Bay. The Silurian rocks of the Notre Dame Bay are much more anophoidal than in proximity to the igneous rocks bearing copper. In fact all of the early Paleozoics appear to be here more metamorphosed than on the eastern side of the Large Range. The serpentine diorite igneous masses simply think broke through after the Silurian and before the Cambri. I told him of the anophoidal Cambri, and the trap (intrusive) seen by me west of Stephenville Crossing (on the map it is Laurentian), but he held these to be the very old rocks. He added that these igneous masses do cut out the Cambri. The Cambri is less deformed than the early Paleozoic formations. The folds are more open. See what the evidence in Murray's Report is for the presence of Devonian.
