Geochemical, Heavy Mineral and Pebble Lithology Data, Surficial Sediment Sampling Program, Wawa Region, Northeastern Ontario
Summarizes previously unpublished geochemical and heavy mineral data from surveys of humus, till, modern alluvium, and pebbles in the area of the Michipicoten greenstone belt near Wawa, Ontario. Information is included on the regional geology, sampling and analytical methodology, processing of data on kimberlite indicator minerals and metamorphosed magmatic massive sulphide indicator minerals, regional geochemical surveys (for gold, base metals, rare-element pegmatites, and miscellaneous geochemical signatures), and regional heavy mineral surveys. Recommendations are made for gold, base metal, rare-element pegmatite, and kimberlite exploration targets.
Quaternary and Environmental Research on East African Mountains
Twenty-six papers form a summary of research on glacial history, paleoclimatology, biogeography, ecosystem disequilibrium. Focus is on detailed chrono-stratigraphic, glacial geologic, and vertebrate paleontologic problems.
Paleoenvironmental Reconstruction in Arid Lands
The 11 chapters provide a wide ranging perspective on some of the problems under investigation and several of the systematic approaches currently in use by those concerned with refining the knowledge of the changing environments in the world's drylands during the latter part of the Quaternary. Dealing with a part of the globe that is highly sensitive to small changes of climate, or other stresses such as human impact, this book brings together a set of excellent reviews that will be of great value to students beginning to understand the subject and to paleoenvironmental scientists actively concerned with finding solutions to problems of the region. Additionally, it will be an invaluable archive of important references covering the subject of arid lands palaeoenvironmental research. This volume achieves the aspirations of the International Geological Correlation Programme.
