SOUTHERN NEW BRUNSWICK. 5 t) 



Original position, and are here represented as pre-Cambrian (Iluronian). 

 A similar plan has been adopted in the case of the rocks of the Letite 

 peninsula with their extension through Deer and Campo Bello Islands ; 

 but as to these the authors feel less confident, they presenting impor- 

 tant ]3oints of difference in comparison both with the typical Iluronian 

 and the Kingston group, while in some of their features they recall the 

 rocks of northern Charlotte and Queens counties, to be presently 

 noticed under the designation of Cambro-Silurian. 



Compared with the typical Huron ian of St. John county, the true 

 Kino-ston rocks appear to include both Divisions 3 and 4. (Eep. 1877-78.) Kingston group

.Between these and the rocks ol Detite peninsula, referred to above, River, 

 there is in Charlotte county an axis of older rocks, which, from the 

 occurrence of limestones in Frye's Island, and other lithological features, 

 may represent a second parallel belt of rocks equivalent to the so-called 

 Lauren tian of St. John. It may be traced from the head of the Long 

 Reach, near the mouth of Jones' Creek, south-west to the L'Etang 

 Harbour. The extension of the Kingston group (Division 5) west of the 

 St. John River "presents precisely the same character as is seen on the 

 east, being composed principally of felsite, felsite schist and diorite. 

 These rest upon the northern side of the syenite and gneiss axis of the 

 Laurentian (report of 1870-71), with a dip of N. .W. < 70°, and show an 

 exjjosed breadth along the river of about three miles. The rocks are well 

 exposed on two roads running west from the river road to the Finlay 

 settlement, about two and a half miles from the river. On the more 

 northerly of these two roads a reverse dip < S. 55° E. < 70° is seen, 

 showing that the synclinal structure of the centre of the Kingston 

 peninsula is maintained westward ; a little further west the dip again 

 changes to the north-west, indicating the extension of the anticlinal 

 which runs along the south shore of the Long Reach. Between 

 Finlay settlement and Lepreau River the rocks of this group have not 

 been traced, but on that river they again appear directly on the strike 

 and present precisely similar characters. West of the Lepreau, good 

 sections are presented along the St. Andrews post-road, as well as on 

 the road leading down to the mouth of New River, the general dip on 

 both these roads being S. 30° E. < 40°-70°. They extend in a continu- 

 ous section to Barnaby's Head on the west side of Lepreau Harbour, near 

 the extremity of which is a reverse dip> to IS". 60° W. < 50°, which may 

 possibly indicate the southern line of contact with the syenitic gneiss 

 described in former reports as extending west from St. John to Lepreau. 



The eastern extension of the main ridge of Kingston rocks termi- Eastern 

 nates at the road leading from Norton station to Belleisle corner, when Kington Rocks, 

 it becomes covered over by Lower Carboniferous sediments, which 

 occupy the greater part of the Kennebecasis valley to the eastward ;
