Diversity and subduction zone processes of Paleozoioc ophiolites in Japan

我们发表了一篇关于本州东北部古生代蛇绿岩超镁铁质岩体的论文，报道了它们的岩石学多样性，并与中生代和古生代碎屑沉积岩中已有的Hayachine-Miyamori蛇绿岩和尖晶石颗粒进行了对比，讨论了它们的成因。然而，Abukuma山脉的超镁铁质岩石可能是Gosaisho带侏罗纪蛇绿岩的碎片，还需要进一步的研究来证实这种可能性。对北上山脉北部的古生代和三叠纪绿岩及其伴生的沉积岩进行了研究，我们正在准备一篇论文来讨论它们的大洋高原岩浆作用和随后的增生过程。我们还发表了一篇关于蒙古古生代绿岩的论文，并将其与非常相似的日本例子进行了比较。

We have published a paper on ultramafic rock bodies of the Paleozoic ophiolites in Northeast Honshu, reporting their petrologic diversity and discussing their origin in comparison with the well-studied Hayachine-Miyamori ophiolite and spinel grains in the Mesozoic and Paleozoic clastic sedimentary rocks. However, ultramafic rocks in the Abukuma Mountains are possible to be fragments of a Jurassic ophiolite of the Gosaisho zone, and further studies are needed to verify this possibility. Paleozoic and Triassic greenstones and associated sedimentary rocks were studied in the northern Kitakami Mountains, and we are preparing a paper to discuss their oceanic plateau magmatism and subsequent accretionary processes. We also published a paper on the Mongolian Paleozoic greenstones, and compared them with the well resembling Japanese examples.
