The paper provides brief information about the evolution of the notion of ophiolitic complex structure. Today, the oceanic crust structures are characterised by reference cenotype settings of ophiolite formation: oceanic spreading zones, back-arc basins, island arcs mainly trending toward the ocean, and oceanic islands. The paper gives specific features of ophiolitic formations in the given cenotype settings, together with characteristics of ophiolitic folded regions and their comparison with reference types.

Key words: ophiolites, reference cenotype settings, basalts, hyperbasites, spreading, subduction.
