Intrusive and tectonic history of the Sudbury micropegmatite; the evidence from paleomagnetism

A paleomagnetic analysis of over 600 specimens of Sudbury micropegmatite indicates the presence of five distinct remanence directions. Four of these directions are similar to directions previously reported from the Sudbury norite. A chronology of remanence acquisition events was erected on the basis of one positive contact test and the relationship of the remanence direction to regional geological structures, with additional information from …
