Abstract
Bodies of massive ground ice are commonly associated with deposits of granular materials in the Mackenzie Delta - Beaufort Sea region. In this paper, data on ground ice occurrences in granular deposits of glaciofluvial origin have been summarized from geotechnical borehole data collected from previous investigations of potential granular resource deposits in the region. Information of the nature and frequency of the ice bodies, and their association with adjacent sediments and landforms is presented. Many of the ice layers are thin and occur at shallow depths, apparently associated with organic materials or the base of the active layer. Other ice layers are very thick, in many cases extending below the depth investigated. A significant proportion of the ice bodies occur within the granular sediments, not at lithostratigraphic boundaries. The results of this study are discussed in terms of possible interpretations of the origin of the ice, and of their implications on the exploitation of granular resources. (Author) | Frequency reviewed by using geotechnical bore-hole data collected as part of granular source investigations in this area over last 20 years. Character of ground ice is discussed in terms of surficial geology of area, with interpretations of origin of ice and implications for exploitation of granular resources
