A successful method of mineral exploration in glaciated terrain is the use of indicator minerals recovered from carefully selected glacial sediments, and sub- sequently . The Quaternary stratigraphy of the Babine Lake region is characterized by a Late Wisconsinan succession of advance-phase glaciolacustrine sediments, glaciofluvial deposits, Cited by:
Continental glaciation was widespread in eastern Gondwana during Paleozoic time, and is especially well recorded in rocks of Late Ordovician age, in Saharan Africa and in the Cape Ranges of South Africa. Glaciers apparently also flanked a basin in the Central Andes in early Silurian time, and perhaps as well in the central Cited by: 5. Research interests include: 1) glacial micromorphology of tills and subglacial processes controlling mineral dispersion; 2) applications of isotopes and trace element geochemistry to base metal indicator minerals; 3) continental ice sheet reconstructions and glacial history, and 4) impact of former ice streams on landscapes and mineral Title: Research Scientist at .

Ice flow history and drift composition were studied in central Labrador to establish a geological framework for mineral exploration. Glacial history, drift composition, and mineral exploration, central Labrador. Geological Survey of Canada, Bulletin 82p. Some or all of the raw data associated with this.
The work is intended to show ways in which regional geochemical survey data can be used for mineral exploration. The study area lies between latitudes 52°30′N and 55°30′N, and longitudes 65°W and 69°W, including parts of western central Labrador and adjacent eastern Quebec.
It is well suited for modeling glacial dispersal because of marked contrasts in bedrock geology and a complex glacial by: Heavy mineral methodss have become an important exploration tool in glaciated terrain for gold and base metals and, in the last ten years, for diamonds.
Lake sediments and biogeochemical methods are also included in this volume as a complement to geochemical and indicator mineral methods in glaciated terrain.

Drift prospecting utilizing till as a sampling medium is still in its infancy despite the fact that its principles have been known in the western world for at least years. Much more research is needed the better to define modes of entrainment, transportation, and deposition of glacial : William Shilts.
Drift prospecting is defined as the application of glacial geologic, geochemical, geophysical and sedimentological techniques to the problem of mineral exploration in areas mantled by glacial overburden.

Together, the empir-ical and theoretical models provide a regional framework for developing mineral exploration strategies in terms of glacial process and its effects on drift composition.
