Book excerpt: Excerpt from A History of New Brunswick Geology His third season's work embraced generally the counties of St. John and Kings, with a very complete description of the Grand Lake coal-field. The fourth described the western portion of the province as far north as Woodstock, on the River St. John, with the country contiguous to that river, as well as the character of the coalfields lying along the Main South-West Miramichi River, while the fifth included generally the area lying north of a line extending from Woodstock to Rathurst, on the Bay of Chaleurs. Considering the state of geological science in that early day, the reports of Dr. Gesner contained a large amount of valuable information. It must be borne in mind that the nomenclature of the science was very limited. The grand formation which now comprises the fundamental rocks of our record, the Laurentian, had not then received its now world-wide designation, nor had the term Huronian been even thought of. The divisions into Primary and Secondary, Old and New Red Sandstone, Coal measures and granitic rocks, composed the bulk of the geological scale. There could, therefore, have been no attempt to separate the rocks of the older systems into such an arrangement as now exists. But Gesner evidently did a large amount of good work in the delineation of his areas of Coal measures and New Red Sandstones, his Transition or slate and limestone group, and his volcanic rocks, though many of his boundaries were, of necessity, from the sparsely settled and, in consequence, comparatively inaccessible character of the country, far from correctly laid down, and the stratigraphical order, as given in his reports, is, in some cases, the reverse of what is now known to be the true position. He pointed out also the presence of the two great areas of granitic rocks which traverse the province, one along its southern portion, the other diagonally across the northern half, extending southwesterly into the State of Maine, where these two areas evidently unite. They were considered by him as of Primary age, and included a large proportion of the felsitic rocks, with which, in some places, the granites are intimately connected. He held that these so-called Primary ridges were flanked by beds of Cambrian age, consisting of slates and hard-grained sandstone, styled by him greywacke, while to the north of the northerly belt the great Silurian fossiliferous area of slates and limestones was clearly indicated.
