AbstractLate Wisconsinan, Fraser glaciation till is the most extensive surficial sediment in the Highland Valley Copper mine (porphyry Cu-Mo) area. During the Fraser glaciation, ice flowed predominantly south to southeastward as indicated by the orientation of drumlins and flutings. During deglaciation, lateral meltwater channels cut into the flanks of valleys and mountain slopes, indicating that ice occupied low ground when higher elevations were ice free. Accumulations of glaciofluvial sand and gravel, too small to be mapped at this scale, can be found close to these meltwater channels. The glaciofluvial drainage was generally to the south during ice retreat, with aggradation of glaciofluvial sediments in the Guichon Creek valley. Glaciolacustrine sediments in the Witches Brook valley were deposited in a lake that formed when the eastward drainage was blocked by a mixture of ice and sediments. Mine tailings blanket areas near open pits and in the valley that extends northwest from the mine (previously occupied by Pukaist Creek).
Summary(Plain Language Summary, not published)
This map depicts the distribution of unconsolidated sediments present at the surface in the region of the largest copper open pit mine in Canada. The region has received a lot of interest from the mineral exploration industry because it hosts copper mineralization in bedrock. The unconsolidated sediments present in the region dominantly consist of material deposited by glaciers (till) with lesser amount of sand and gravel deposited by glacial meltwater and modern streams, and lesser amount of silt and clay deposited in glacial lakes that formed at the end of the glaciation. Landforms sculpted and deposited by glaciers are represented with point and line symbols. These are particularly useful to interpret the glacial and ice-flow history of the region. The map has a variety of usage: 1) reconstruction of ice-flow history as applicable to mineral exploration; 2) identification of granular resources; and 3) environmental applications (e.g. groundwater, waste site, etc.).
