Abstract:

Volcanic rifted margins are a kind of continental margin formed during continental breakup. Their geodynamic evolution is as complex as that of active margins. Through the study of continental breakup and evolution of passive margins in recent years, the recognition of these margins has greatly improved knowledge of their sedimentary process, magmatism and metamorphism. Several models have been proposed for continental breakups. The asymmetry simple shear model may explain the genesis of volcanic rifted mar...
