AbstractAll glacial deposits in the Clyde Forks-Westport area are thought to be Late Wisconsinan or younger. The dominant direction of glacial flow during the Late Wisconsinan was south-southwestward. The most widespread surficial deposit is sandy, stony till. Glaciofluvial sands and gravels are widely distributed, and include deposits associated with three prominent esker-subaqueous fan systems. Laminated glaciolacustrine fine sand and silty clay occur in low-lying areas west of Perth and southeast of Westport. Similar silty clay deposits in the vicinity of Perth and Smiths Falls may be marine. Regional variations in carbonate content of glacial sediments and till texture reflect most strongly the effects of glacial transport. Concentrations of Paleozoic limestone clasts (2 .0-5.6 mm) and clay-sized detritus in till are high overlying Paleozoic terrane in the eastern part of the study region and over an area of Precambrian terrane which extends over 20 km west and southwest of the Paleozoic-Precambrian boundary. Much of the Precambrian terrane is underlain by carbonate-poor lithologies. In contrast, the trace element content of the clay-sized fraction of drift reflects, in most areas, composition of the underlying or nearby bedrock. For example, concentrations of As, Au, Hg, Cu, Pb, and Fe, are high over a major structural zone - the Robertson Lake Mylonite Zone where many known showings of gold and sulphide minerals are known. Further drift prospecting is recommended in the vicinity of the Robertson Lake Mylonite Zone as its mineral potential is largely untested.
