It also contains fragments of reddish sandstone and a few pieces of impure slaty limestone. The conglomerate is overlaid by thick beds of purple clay slate, which by the accession of coarser materials becomes a slaty sandstone and grit filled with white particles. The highest member on the line of section is a slaty conglomerate holding fragments of...
Page 62 - Works the rocks of the more northerly anticlinal ridge present the following succession : — Hard greenish-grey petrosilicious rock, with very obscure stratification ; conglomerate with bright red slaty paste ; grey conglomerate ; coarse reddish grit and conglomerate, with purple sandstone : apparent thickness of the whole, 5,000 feet.

Page 135 - The actual thickness, however, may be much less than this, for while there are numerous faults and folds for which allowance is made in the above estimate, a repetition of similar sediments on either side of the trough of these rocks upon which the city of St. John stands, would appear to indicate that the entire series, with the undei lying Huronian strata, is here folded upon itself in a sharp synclinal, overturned to Overturn, the northwest. In this case, the aggregate thickness of the series,...
Page 291 - Bands of crystalline limestone are easily distinguished from bands of gneiss, but it is scarcely possible to know, from mere local inspection, whether any mass of limestone in one part is equivalent to a certain mass in another.
