The publication of the textbook of Coleman (1977), the beginning of mobilistic models (tectonic nappes, obduction, terranes, accretion) the use of a considerable amount of geochemical analyses (including Sr isotopes and tectono-magmatic diagrams) of igneous rocks (Fig, 4), together with sedimentology of the radiolarites, and extensive mapping dominated this stage of scientific research.
