摘要
There is a general consensus that most ophiolites on the earth formed above a subduction zone and they often display a characteristic, sequential evolution of MORB to island arc tholeiities （IAT） to bonnites （Dilek et al., 2010, 2009; Pearce et al., 2003）. However, ophiolites occurred in a continental margin are very rare and usually have more complicated, irregular components, such as N-MORB,
