摘要

INTRODUCTION Magmatism plays a key role in the process of continental margin breakup and ocean formation.Even in the extremely magma-poor Iberia and Newfoundland margin,studies of field outcrops have shown that syn-rift magmatism had participated in rifting from a very early stage and contributed directly to the rifling process.The final transition from exhumed continental mantle to the ocean formation is also triggered by the accumulation and eruption of magma [1].Therefore,Atlantic-type passive continental margins are classified into two end-members:magma-poor (non-volcanic) and magma-rich (volcanic).
