geological sketch map, the strata consist of zones or bands 

 of quartzose sandstone or quartzite and conglomerate 

 alternating with bands of shale or slate. The strata, 

 in a general way, strike east and west and are traversed 

 by a series of faults striking to the west of north. The 

 fault planes are presumably vertical or nearly so and in 

 the cases of all the faults observed the strata on the western 

 side of the fault plane, relatively to the strata on the 

 eastern side of the fault, are displaced towards the north. 

 Besides these more easily detected faults that strike in a 

 northerly direction, there are also present others striking 

 in an east and west direction. 



The strata of the zone of quartzite and conglomerate 

 traversed by Bic river, south of Bic harbour, is, in its 

 northern portion folded into an open synclinal form, and 

 the quartzites and conglomerates therefore overlie the 

 dark shales exposed along the railway. Possibly the 

 two bands of quartzite on the northern side of the estuary 

 of Bic river, represent tightly compressed folds of the 

 same quartzite horizon, but the evidence is not complete 

 in this respect. In the case of the broad belt of quartzite 

 and conglomerate south of the railway, the southern 

 portion, south of the synclinal axis referred to, apparently 

 is folded into an anticline, and along the southern border of 

 the area, the quartzites dip steeply beneath dark shales 

 interbedded with light coloured, fine grained sandstones. 



Fossils occur in the conglomerates at Bic at a number of 

 points. One of the more readily accessible of these is a 

 short distance west of Bic sta ion and to the south of the 

 railway. The first conglomerate band south of the 

 railway, at this point, contains many fossiliferous lime- 

 stone pebbles, in which the must common fossils are 

 Olenellus thompsoni, Protypus senectus and Microdiscus. 



The general geological structure and the nature of the 

 stratigrapl.xal divisions may be observed if the road 

 leading southward from Bic station is traversed as far as 

 the cro&sing of Bic river, and if also the road leading 

 n^' Ji westward along the eastern side of Bic harbour is 

 followed to its ending. 



A very short distance west of Bic station and immediately 

 south of the railway, there rises a partly wooded ridge 

 extending for some distance west of Bic but ending abruptly 

 on the east just south of Bic station. This ridge is formed
