... of detrital minerals that might reflect a specific source terrane (e.g., igneous suite, metamorphic complex, etc .). In some cases, minerals may be identified that might have a unique sediment source region. The MLA data can also be examined to evaluate whether trends of changing detrital mineral...

..., Lower Cretaceous rocks rest on Paleozoic rocks or Precambrian basement in parts of the area. Onshore Labrador, the presence of a Cretaceous outlier on Precambrian basement adds to the evidence of one or more events of exhumation that has removed pre-Cretaceous sediments on a regional scale.

The shallow subsurface geologic conditions within Foggy Island Bay range from loose silty sand and soft to firm fine-grained marine Holocene deposits to stiff Pleistocene silty clay deposits. Shallow permafrost is present in Foggy Island Bay, primarily near...

... in the Arctic Ocean. For a relatively small ocean basin, the Arctic Ocean reveals a plethora of margin and basin types reflecting both the complex tectonic origins of the basin and its diverse sedimentation history. Broad and narrow shelves were subjected to a complex ice-margin history in the Quaternary...

... Abstract In Arctic regions, permafrost and gas hydrate bearing sediments below the seabed present a technical problem for drilling operations. The first and most important challenge is to be able to control the well if pressured gas is encountered in or below such formations, and the second...

.... The permafrost soil layers surrounding arctic wells will thaw gradually withtime due to wellbore heat loss. As the thaw zone advances radially outward fromeach well, the ice-to-water phase change within the pore space of thefrozen/partially frozen sediments will lead to changes in the permafrost soilproperties...
