Lithogeochemistry and spinel compositions in the ultramafic complexes of Western Ethiopia : criteria for the identification of Alaskan-type intrusions
This thesis covers two separate but complimentary themes. Firstly, work on the spinel composition of the ultramafic rocks of has provided evidence that they formed as Alaskan-type intrusions. This has implications both for prospectivity and for the understanding of neoproterozoic plate movements. Ad...
