Project Metadata

Airborne collection of surficial materials for geological and geochemical studies dates back to at least the early 1970s.  Geochemical analysis of tree-top samples taken from a helicopter by the United States Geological Survey found that the technique was effective in locating anomalous target areas.  In 1988, tree-top sampling was carried out over the Quesnel River (QR) gold deposit 140 km southeast of Prince George in central British Columbia.  The purpose of this project was to help develop some of the less traditional exploration techniques for gold and to add to a reference database of elements in common plants.  An interpretation of the survey can be found in Journal of Geochemical Exploration v.34.
