pitching anticlines. Gold was discovered about fifty years 

 ago and since that time the district has received the 

 attention of many geologists. 



The series is remarkable perhaps not so much for the 

 amount of precious metal produced as for the enormous 

 thickness of conformable sediments exposed, for the inter- 

 esting variety of schists produced by igneous and dynamic 

 agencies, and more specially for the beautiful dome- 

 structure of the interbedded veins, the origin of which has 

 provoked the constructive imagination of geologists for 

 the last fifty years. 



The geological structure of the greater part of the area 

 of the series, from the eastern extremity to Liverpool and 

 Kentville, has been surveyed in considerable detail for 

 many years by E. R. Faribault [10], and the results have 

 been published by the Geological Survey on map-sheets on 

 the scale of one mile to an inch, on detailed plans of mining 

 districts, and in many partial reports contained in the 

 annual Summary reports. The southwestern portion of 

 the region was mapped and reported on with less detail 

 for the Geological Survey by L. W. Bailey. In the report 

 compiled by W. Malcolm [11] and published in 1913 by the 

 Geological Survey, entitled "Gold Fields of Nova Scotia", 

 is presented a comprehensive and complete record of the 

 results of the investigations made in the field. The present 

 review of the subject is largely an abstract of that report. 



The whole surface of the area of the Goldbearing series 

 has been subjected to extensive erosion and all that remains 

 of what was probably once a highly elevated mountain 

 system, is a plateau reduced nearly to sea-level, showing 

 the upturned edges of the closely folded beds and the low 

 granitic masses that intruded them. The plateau has a 

 general southerly slope towards the Atlantic, and its 

 northern limit forms a long escarpment whose elevation 

 varies in altitude from 500 to 800 feet (152 to 243 m.). 



THE GOLDBEARING SERIES. 



The Goldbearing series is one of the oldest series of 

 sedimentary rocks in the province. It extends along the 

 Atlantic coast the whole length of the peninsula, but is not 

 represented in Cape Breton Island. The extreme length of 

 the series from Canso to Yarmouth is 275 miles (442 km.) 

 and the width varies from 10 miles (16 km.) at the eastern
