Kilometres south at the crossing of Little river, are expos- 

 ures of biotite granite belonging to a large body 

 which cuts and highly alters the surrounding 

 Ordovician strata. The granites occupy an area 

 of about 80 square miles; the granite body is 

 presumably of much greater area than this 

 since its eastern portion is hidden by a mantle 

 of younger, Carboniferous strata.

NIFISIGUIT JUNCTION TO BATHURST MINES. 



(G. A. Young.) 



57 • 4 m. Nipisiguit Junction — From Nipisiguit Junc- 



92-4 km. tion the Northern New Brunswick and Sea- 

 board railway runs southward up the valley of 

 Nipisiguit river to Bathurst Mines distant 

 about 17 miles (27-3 km.). The railroad for 

 most of the distance, passes through the forest 

 out of sight of the river. Along the river ex- 

 posures of granite continue for a distance of 

 about 6 miles (9-6 km.). From the southern 

 boundary of the granite batholith to near the 

 Great Falls on the Nipisiguit river, the exposed 

 strata are apparently of Ordovician age — bands 

 of dark slates like those on the Tetagouche river 

 alternating with others of green, probably tuff a - 

 ceous, rocks. The strata are closely folded and 

 much faulted. 



At about the fourteenth mile the wide stream 

 bed of the Nipisiguit river is visible from the 

 railway. About a mile farther, the gorge of the 

 river below the Great Falls, comes into view. 

 The lower portion of the gorge has been cut 

 through black slates dipping upstream at high 

 angles. The upper portion of the gorge is in 

 quartz porphyry overlying the dark slates. At 

 about the sixteenth mile, the crest of the falls 

 may be seen from the railway, and from this point 

 to Bathurst Mines the railroad passes close to the 

 river edge through many cuttings in sheared 

 quartz porphyry.
