Paleozoic ultramafic volcanic rocks of superplume origin in the accretionary complexes of Japan and its vicinity

这项研究的成果已经发表在许多国际期刊论文上。Ichiyama&Ishiwatari(2005)报道了侏罗纪Mum增生杂岩中富钛和富HFSe苦味石的地质产状、化学和矿物学特征，并讨论了其在二叠纪超柱岩浆作用中的成因。Koizumi和Ishiwatari(2006)报道了侏罗纪坦巴增生杂岩中两种截然不同的绿岩产状和化学特征，即基底推覆型和混杂岩型，并分别将其成因归因于大洋高原和正常大洋漂浮。(2006)报道了产于坦巴带增生绿岩中的铁皮榴石的化学和同位素组成，讨论了它们的成因与大洋地区二叠纪超柱岩浆作用的关系(2007年Ichiyama et at(2007)首次报道了该地区显生界中的橄榄石-尖晶石玄武岩)，并与…对比讨论了其地质意义。更多类似于科拉半岛佩琴加地区的元古界岩石和脊椎动物繁殖实验的结果。Ichiyama et at(2008)根据不同的钛含量将基底推覆型绿岩划分为3组，并讨论了它们的地质和化学演化与二叠纪洋区超柱头部和尾部岩浆活动的关系。我们的相关结果包括Ishiwatari等人。(2006)首次报道了伊豆-博宁-马里亚纳弧埃达克岩的存在，描述了火山岩、辉长岩和橄榄岩的分布和化学-矿物学多样性，并提出了博宁前弧的Hahajima海山是由几个蛇绿冲断片组成的地垒地块的模式，该地块是小川高原碰撞俯冲而上升的。Yanagida等人。(2007)报道了从马里亚纳海沟南部向陆坡挖出的变质橄榄岩中的镁微晶橄榄岩，表明地幔橄榄岩具有极广泛的矿物化学多样性和较低的平衡温度，并提出在海沟斜坡上暴露出弧前-弧后地幔段。Ishiwatari et at(2007)报道了俄罗斯东北部Pekulney山脉非常罕见的大型石榴石橄榄岩-超镁铁质杂岩。较少

The results of this study are already published as many international journal papers. Ichiyama & Ishiwatari (2005) reported geological occurrence, chemistry and mineralogy of meimechite (Ti and HFSE-rich picrite) from the Jurassic Mum accretionary complex, and discussed its origin in the Permian superplume magmatism. Koizumi & Ishiwatari (2006) reported two contrasting occurrences and chemistry of greenstones in the Jurassic Tamba accretionary complex, namely basal nappe type and melange type, and attributed their origin to oceanic plateau and normal ocean float respectively Ichiyama, et al. (2006) reported chemical and isotopic composition of ferropicrites occurring in the accreted greenstones of the Tamba belt, and discussed their origin in relation to the Permian superplume magmatism in the oceanic area Ichiyama et at (2007) further reported olivine-spinifex basalt from the same area for the first time from the Phanerozoic, and discussed its geological significance in comparison wit … More h the similar Proterozoic rock occurring in the Pechenga area, Kola Peninsula and the results of spinifex reproduction experiments. Ichiyama et at (2008) divided basal nappe-type greenstones into 3 groups by distinct Ti concentration% and discussed their geological and chemical evolution in relation to the magmatism of a superplume's head and tail in the Permian oceanic area. Our related results include Ishiwatari, et al. (2006), which reported occurrence of adakite Sr the first time from the Izu-Bonin-Mariana arc, depicted distribution and chemical-mineralogical diversity of volcanic rocks, gabbros and peridotites, and presented a model that the Hahajima Seamount in the Bonin Forearc is a horst block composed of several ophiolitic thrust sheets that was uplifted due to collisional subduction of the Ogasawara Plateau. Yanagida et al. (2007) reported Mg-cummingtonite from metaperidotites dredged from the landward slope of the southern Mariana Trench, showed extremely wide mineral-chemical diversity and low equilibration temperatures of the mantle peridotites, and proposed that a forearc-backarc mantle section is exposed on the trench slope. Ishiwatari et at (2007) reported very rare, large-scale garnet peridotite-ultramafic complexes from the Pekulney Range, northeastern Russia. Less
