Glacier glaciations

Glaciers are powerful agents of physical erosion. In a detailed geomorphological study of the glaciated Canadian Shield, Sugden (1978) concluded that erosional style was related primarily to the basal thermal regime of the ice. From the center of divergence on an ice cap. 

The Thompson Nickel Belt (TNB), Manitoba, Canada, is host to world class magmatic massive sulfide Ni-Cu-PGE deposits. The deposits subcrop beneath 2 to 30 m of glacial sediments and have been eroded by glaciers flowing SW and then Wduring the Wisconsin glaciation. 

Reservoirs, which are virtually exclusively situated in the alpine region, generally store water from glaciated catchments. In low-precipitation years, snow and ice melt from glaciers compensates for runoff deficits, and in so doing permanently... 

Glaciation A time period when glaciers more extensively covered continents and high mountains than at present. The last major glaciation ended about 11 500 years ago. 

Similar observations in Red Spider Cave, northwest Georgia, provided a good pollen record over the past 40,000 years, thus allowing interpretation of the local climate through the last glaciation in an area well south of the glacier margins (Brook and Nickmann, 1996). 

Each team performed an uncoupled transient flow simulation. The spatial distribution and evolution of the simulated head are qualitatively similar to the coupled H-M simulations above a certain depth, which varies with time from near surface to 900-m depth. Below this depth, due to the very low rock permeability there is hardly any hydraulic response to glaciation. Residual excess pressures similar to the coupled H-M model results are predicted 9500 years after glacier is gone. In this case, however, the values (350-400 m of pressure head) are almost twice as high.
