AbstractMore than 25 government, university, and industry researchers were active during the 1997 field season of the joint Geological Survey of Canada and British Columbia Geological Survey Branch Nechako project. In addition, university students assisted in the mapping programs. Bedrock geology was mapped in eleven 1:50 000 scale areas and surficial geology in five 1:50 000 scale areas. Researchers sampled till, silt, lodgepole pine, and rocks in various geochemical studies. Others measured paleomagnetic signatures, studied biostratigraphy, sampled for isotopic age determination, and conducted detailed sedimentological and stratigraphic studies. New geoscience contributions include 1) defining the distribution of Jura-Cretaceous volcanic stratigraphy in northern Nechako River map area, 2) more clearly defining Eocene felsic and mafic volcanic stratigraphy and crustal structures, 3) detailed differentiation of Cretaceous and Eocene felsic igneous suites of the Babine Belt, 4) improved constraints on Pleistocene ice-flow and lacustrine deposits, and 5) characterizing Cache Creek and Sitlika groups biostratigraphy and tectonostratigraphy.
