In many respects the St. John Group in this valley differs from the same terrane as developed in the St. John valley or basin, meaning by this the basin of Cambrian sediments which stretches eastward from the city of St. John. At the foundation of these differences is the fact that the area intervening between these two valleys, through long ages in the past, not only since the Cambrian Age, but previously, has been an area of elevation, flanked on each side by belts of the earth's crust that were subject to depression. The Kennebecasis valley was outlined in Pre-Cambrian times by a great fault along its northern side, along which were poured out from the earth's interior great quantities of effusive rocks. These effusives were chiefly thrown out upon the north side of the fault upon a sinking area of the earth's crust, which now forms the peninsula of Kingston Neck. Complementary to this sinking of the land on the north side of the fault, there was an elevation of the mass on the south side, so that then and at a later time this side was subject to great denudation. (The accompanying sketch map has been made to show the Cambrian outcrops in the Kennebecasis valley, and to make clear the relations of the Cambrian system in this valley to the older and younger rocks there. For the data contained in this map I am indebted in part to the courtesy of the Director of the Geological Survey of Canada, and partly to Dr. W. D. Matthew, who mapped the area between the city of St. John and the Kennebecasis valley when studying the igneous rocks of this area.) The elevatory movement of the rocks south of the great fault, which began in Pre-Cambrian times, continued until the beginning of the Cambrian, for over a considerable area on this side of the fault (perhaps 200 square miles) we find no trace of the Etcheminian series, the series which comes immediately below the Cambrian, but the Cambrian measures rest directly on rocks of Laurentian age. Nor do we find any trace of the Etcheminian series on the effusive rocks which form Kingston Neck, an area quite as large as that above referred to. But while we discover here an area of elevation in ancient times, lines of weakness were developed in it at the opening of Cambrian time, more or less conformed in direction to the main fault. These lines of weakness were no doubt lines of faulting, and in the hollows thus produced Cambrian sediments in thin masses were laid down; in these sediments we recognize by the faunas they contain the Divisions 1 and 2 of the series in the St. John valley. This area, with subsidiary faults, is about three miles wide, and now forms the valley of Kennebecasis river. The more resistant area to the south forms the ridge which separates that river from the St. John basin of Cambrian rocks. The next step in the history of the Cambrian deposits in this valley of which we have evidence was the crushing together of the beds into close folds, which took place in the Devonian Age. In consequence of this squeezing process the strata are almost everywhere on edge, and, owing to this and the limited exposures, no consecutive order can be traced in them; and for their interpretation we have to depend on the paleontology and on the resemblance of the several parts to the sediments of the St. John basin. Intrusive rocks have cut the Cambrian beds of the Kennebecasis valley at several points. Dr. W. D. Matthew, who has examined some of these, found them to consist of augite-porphyry and basalt, and thus to differ from neighbouring intrusives of the Laurentian system, which are diorite-porphyrite and quartz-diorite; and of the Huronian system, which are diabases. Some of the intrusives of the St. John Group in this valley have come out near or along old pre-Cambrian fault-lines, showing a relation of the post-Cambrian to the pre-Cambrian lines of disturbance. At a still later time than the Devonian when the great disturbance and folding of the Cambrian took place, a period of depression again set. in in the valley of the Kennebecasis, with a counterbalancing elevation of the Laurentian ridge to the south, and the valley was filled with sediments swept down chiefly from the Laurentian hills. These deposits were mostly conglomerates, shales, and sandstones, of Lower Carbonif erous age, which completely buried and concealed the Cambrian rocks. Later movements of the crust along fault lines in this valley in the Mesozoic Ages and the great denudation that occurred then and in Tertiary times, again brought the Cambrian rocks to the surface, but only |
