Opis

The well-known concept of plate tectonics long dominated notions of stratified structure of ophiolite associations and overlap gabbroides on ultramafites. This book presents data that does not agree with these views and suggests an earlier introduction of protrusions of ultramafic upper mantle restites against the intrusions of gabbroi
