‘MARBLE AT FAULT’ Project No. 13/67 Why did the Northern Exploration Co. abandon its marble quarries on Blomstrand? © Frigga Kruse 2015 Blomstrand, or Marble Island, has a colourful history: • • • • • • Ernest Mansfield described an island of marble in 1906 The Northern Exploration Co. began operations in 1911 The NEC was absent during WWI Quarrying was renewed in 1919 The site was abandoned in 1920 © Frigga Kruse 2015 Why? A shallow marble quarry opened in 1919 © Frigga Kruse 2015 Fracturing is ongoing on Blomstrand today © Frigga Kruse 2015 We looked in great detail at the rock surrounding old quarries and boreholes © Frigga Kruse 2015 We used groundpenetrating radar (GPR) to look at the subsurface © Frigga Kruse 2015 Was the rock around the old quarries and boreholes disturbed or did it have economic potential? © Frigga Kruse 2015 What other reasons may have led to the abandonment? Archival research might provide an answer. © Frigga Kruse 2015 Some disturbances were clearly visible at the surface. The GPR survey revealed areas of disturbances but also intact rock. How much waste rock is too much waste rock? Large fault in old quarry © Frigga Kruse 2015 Irregardless of the quality of High Arctic marble and the ease of working it, the documents indicate that global markets and a lack of demand may yet be to blame.
