Archaean rocks cover roughly one-third of the Precambrian region in the Fennoscandian Shield. This volume provides a review of previous studies and presents new data on the geochemistry, age determinations, metamorphism, palaeomagnetism and petrophysics of the Archaean rocks of the Finnish part of the Karelia Province, and discusses the magmatic and tectonic processes that could explain its present constitution and structure. Extensive new data are presented on U-Pb age determinations on zircon from volcanic rocks and metasediments in the greenstone belts and adjacent areas, and on Sm-Nd analyses all over the Karelia Province in Finland--P. 4 of cover.
