One is a bimodal volcanic assemblage, which formed during the rifting stage of the continental breakup theother is represented by flysch rocks, formed when the passive margin becomes stable. The composition of mafic rocks in the volcanic margin reflect their mantle origin and their crustal contamination. High temperature and low-pressure metamorphism can occur during the rifting stage and reflects a temporal trend of increasing temperature and decreasing pressure during the continental breakup.
