Surficial geological mapping in the central Kluane Ranges was undertaken to better understand the distribution and character of surficial materials. Upland surficial materials in the area are dominated by near-source bedrock derivatives. Valley bottom settings, including Shakwak trench and Duke River valley, are characterized by broad open valleys with thick deposits of Quaternary sediment. Permafrost is discontinuous in the study area and its character is affected by slope and aspect, topography and material texture. Mass wasting processes in the study area include rockfall and avalanches, debris flows, debris avalanches and active layer detachment slides. The distribution and character of surficial materials are significant for soil geochemical sampling programs, mineral exploration, infrastructure and development.

Canadian Geoscience Knowledge Network WMS provides national coverage geoscience layers

This layer contains polygon features that represent the generalized surficial geology of New Brunswick. Unconsolidated materials occurring over bedrock, are classified according to physical attributes and genesis, and categorized into map units. This layer is intended to be used at small scales (e.g., provincial scale). It is an update of the 2002 Generalized Surficial Geology Map of New Brunswick, the updates reflect re-interpretation of the geology based on additional field investigations.
