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，报告了它们的岩石学多样性，并与研究充分的Hayachine-Miyamori蛇绿岩和中生代和古生代碎屑沉积岩中的尖晶石颗粒进行了比较，讨论了它们的起源。然而，阿布熊山脉的超镁铁岩可能是五斋庄带侏罗纪蛇绿岩的碎片，需要进一步的研究来验证这种可能性。我们对北方北上山脉的古生代和三叠纪绿岩及相关沉积岩进行了研究，并正在准备一篇论文，讨论其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，并将其与日本的类似井实例进行了比较。

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.
