Geokjemiske undersøkelser av kaledonske vulkanitter og intrusiver i Midt- og Syd-Norge.

It has been possible with the aid of whole rock geochemistry to make a start at understanding the Caledonian volcanic belts in Norway, so that we can now progress beyond the stage of considering them under all-inclusive terms such as "greenstone", "basic volcanics" and other generalizations and begin to think in terms of specific magmatic types, e.g. island arc tholeiites, island arc calc-alkaline suites, ocean floor type lavas, etc.. It has recently been shown that a knowledge of the environment of magma formation can have considerable bearing on understanding local stratigraphy and in correlating non-fossiliferous units containing volcanic rocks as well as being absolutely necessary in establishing a plate tectonic model for the Caledonides (Gale and Roberts, 1974).
