9503538 Batiza This area of the EPR has been extensively studied and Batiza has collected an impressive set of samples from three transects that cross the ridge axis. These allow him to evaluate the evolution of the magma chamber over a period of about 1 m.y. Results to date indicate that one of the ridge transects, the one with less magma, only erupted MORBs but the two other erupted a mixture of N-MORBs and E-MORBs. There are a number of alternatives for these differences and Batiza wishes to do additional analyses of the rocks in hand to evaluate these alternatives. ***

9503538 Batiza对EPR的这一区域进行了广泛的研究，Batiza从横跨脊轴的三个样带中收集了一组令人印象深刻的样本。这使他能够评估大约1英里内岩浆房的演化。迄今为止的结果表明，岩浆较少的山脊剖面之一只喷发了morb，而另外两个则喷发了n - morb和e - morb的混合物。对于这些差异，有许多替代方案，Batiza希望对手头的岩石进行额外的分析，以评估这些替代方案。＊＊＊
