"The Ordovician succession here is practically like that to the north with one marked difference. That are dolomites and limestone in the north to O1,3 where shale followed by sandstone, while here at Bonne Bay the shale phase appeared earlier, firstly as early as the time of M or even L. The shale phase then con- tinued with sandstone and limestone conformable changes to the end of Ordovician deposition. The Long Range Mts take their highest elevation in the region of St Johns Bay and then this altitude of the old Laurentian mass is maintained to the south side of Newfoundland. This axis is of very ancient origin as it is notable that the Cambrian of the two sides is very different. To the north of St Johns Bay the axis may not have existed as here the Benjic crossed it. In Ordovician time these seas also crossed it in the north but to the south of middle Newfoundland there appears little or deposits of this time. The great diorite intrusions are post Ordovician and as none of it cuts the Carboniferous must be older than the latter. I do not as yet know its age closer than this.
