Rare Earth Elements in the Sudbury Nickel Irruptive

Abstract

<p>Rare earth elements have been determined by group separation, radiochemical neutron activation analysis in rocks from the main Irruptive, the sub-layer and sub-layer inclusions from the Sudbury Nickel Irruptive, Ontario, Canada.</p> <p>Rare earth behaviour in layered intrusions in discussed and applied to the Sudbury Nickel Irruptive. The petrogenesis and mutual relationships of the Sudbury rocks are discussed in the light of their rare earth properties.</p>
