AbstractThe Moffat creek area includes the Woodjam porphyry Cu-Au-Mo developed prospect. Between Moffat and Woodjam creeks, this prospect consists of six mineralized zones: Megabuck, Deerhorn, Spellbound, Southeast, Takom, and Three Firs. Till deposited during the Late Wisconsinan Fraser Glaciation is the predominant glacial sediment in the area. Landform-scale ice-flow indicators such as drumlins and crag-and-tail ridges, and outcrop-scale features such as striations, demonstrate that ice initially flowed south-southwest and later flowed north-northwest. Hummocky topography and eskers suggest that deglaciation was, at least in part, via downwasting of stagnant ice masses. Important accumulations of glaciofluvial sand and gravel deposits in the Horsefly River valley, and in lower volumes in the southwest part of the study area, represent sources of construction aggregate. Retreat-phase glaciolacustrine sediments were deposited in the Horsefly area and Beaver Creek valley at elevations of up to 800 m above sea level. These deposits could be contemporaneous with, and related to, higher water levels in the Fraser or Quesnel river systems during deglaciation and the formation of glacial Lake Fraser. Alternatively, they could be related to local damming of the Beaver Creek and Horsefly River drainages.
Summary(Plain Language Summary, not published)
This map depicts the distribution of unconsolidated sediments present at the surface in the region of Moffat Creek in south central British Columbia. The region has received a lot of interest in the last 10 years 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 silt and clay deposited in lakes that formed at the end of the glaciation. Sediments deposited by gravity processes (colluvium) are present on steep slopes. 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) surface environmental applications (e.g. groundwater, waste site, etc.).
