The Faults of Battery Point, Sydney, N. S* — By T. T.

{Read Uth March. I'JOit). 



The Held work for the following paper was clone during the 

 spring of 1903, in the course of studies pursued in the Summer 

 School of Dalhousie University. 



The section under discussion is situated at Battery Point, 

 Sydney, Cape Breton. It extends from a point 200 feet south- 

 of the old railway pier, for about 1,000 feet in a southerly 

 direction. The faulted area begins 134 feet south of the begin- 

 ning of the outcrop, and is about 400 feet long. Some faults, 

 which in the accompanying section are shown as extending to 

 the top of the cliff, may lessen or die out toward the surface ; 

 for the strata are not always easy to correlate. 



The rocks are in the Cai-boniferous Limestone (Windsor) 

 series. They are largely gray calcareous shales, with bands of 

 concretionary clay ironstone, which vary from a few inches to 

 eighteen inches thick. The ironstones have been emploj^ed to 

 determine the displacements, as they are easily distinguished. 

 The average strike of the strata is N. 42° W. (mag.), and the dip 

 11° N. The face of the cliff, near the top, is in many places 

 covered with talus, which rests upon especially resistant strata 

 that stand out below. It is this talus which makes it impossible, 

 in some instances, to determine whether the faults pass unchanged 

 to the surface or die out. In a few cases the latter condition 

 was seen, in many the former. No other outcrops are available 

 to determine the extent of the faults alonp- the strike.
