The Izu-Bonin arc system is sediment-poor(~400 m thick with no accretionary prism)and,therefore,the influence of the altered oceanic crust(AOC)is most likely the source of the documented along-arc lava compositional variations,especially in Pb ***-Bonin arc lava geochemistry suggests an influx of subduction component from an Indian-type ***,samples drilled from the western Pacific geochemical reference site at Integrated Ocean Drilling Program Site 1149 implies subduction of a Pacific-type *** solve the apparent discrepancy of slab input versus arc output in this arc system,samples of the AOC were dredged from vertical fault scarps of the subducting Pacific Plate along a transect from 27.5°N to 34.50 *** range from tholeiitic to mildly alkalic mid-ocean ridge basalts as well as trachybasalts,basaltic trachyandesites,tephrites,and *** ratios also exhibit a range of values(87Sr/86Sr=0.70282-0.70673,143 Nd/144 Nd=0.512552-0.513174,206Pb/204 Pb=18.43-20.00,207 Pb/204 Pb=15.40-15.67,208Pb/204Pb=37.75-39.55).Our results suggest that there is a geochemical variation in the AOC that is neither completely due to seawater or hydrothermal alteration,nor to petrogenetic ***,this variation is the result of the Pacific-Izanagi ridge system tapping into a heterogeneous,plume-polluted mantle source during the Mid-Cretaceous volcanic *** observed Pacific-type AOC is not responsible for the Indian-type Pb isotopic signature of Izu-Bonin arc *** leads us to propose an alternative scenario where the Izu-Bonin arc lava Indian-type Pb isotopic signature originates from slab-derived fluids interacting and adsorbing Pb from an Indian-type mantle wedge through zone-refining.

洋中脊火山玻璃代表地幔源区熔体成分,携带了岩浆作用和洋壳形成的大量信息。通过研究太平洋洋中脊火山玻璃的主量元素地球化学特征,探讨了岩浆作用过程的元素分配特征,结果表明：洋中脊火山玻璃的主量元素成分呈现规律性演化,从基性向中酸性演化过程中,Na_2O的含量从2%逐渐升高至6%,K_2O从〈1%逐渐升高至5%;而Ca O含量从10%~13%逐渐降低至1%,Fe O从9%~13%逐渐降低至3%,Al_2O_3从18%逐渐降低至13%。洋中脊火山玻璃中主量元素分配特征揭示了其分配的不均一性,这可能是受到宏观上地幔不均一性的影响;在同一洋中脊中的火山玻璃成分也存在不均一性,可能是岩浆作用过程中局部动力学机制差异引起的元素分配不均一。

印度洋MOrB（modern mid-ocean ridge basalts）的Pb,Nd,和Sr同位素组成明显不同于太平洋和北大西洋的MOrB。为什么这两个地幔域组成不同?原因仍然不清楚。一个可能的解释是印度洋地幔域的同位素组成特征是一个长期存在的地幔之区域特征,比如在一些曾经占据印度洋区域的特提斯古洋洋壳所显示出来的这种同位素特征。但是少数一些老的印度洋洋壳和特提斯蛇绿岩并不发育印度洋型的同位素组成特征。为了进一步限制印度洋地幔域同位素组成特征的成因,我们分析了几个不同时代的（90-360 Ma）典型特提斯蛇绿岩的MOrB型岩石元素和Pb,Nd,Sr同位素地球化学组成。尽管这些岩石的Sr同位素组成由于晚期的蚀变而不可靠,但是年龄校正的Nd和Pb同位素比值和地球化学数据表明它们所代表的亏损的软流圈地幔源区具有典型的印度洋型同位素组成特征。因此我们认为印度洋洋下地幔很有可能是继承了特提斯软流圈地幔的组成。少数几个印度洋和特提斯区域不具有明显印度洋同位素成分特征的例子,我们认为可能是在构造板块的运动和洋盆的打开和离散过程中,太平洋-北大西洋之下的软流圈地幔局部流入印度洋和特提斯区域所致。同样,在西太平洋边缘盆地地壳中的印度洋型同位素组成特征也可能是印度洋软流圈地幔也流入西太平洋区域所致,或者是在特提斯洋的离散过程中东亚岩石圈物质的拆沉所产生。

The term adakite was originally pro- posed to define silica-rich, high Sr/Y and La/Yb vol- canic and plutonic rocks derived from melting of the basaltic portion of oceanic crust subducted beneath volcanic arcs. It was also initially believed that ada- kite only occurs in convergent margins where young and thus still hot oceanic slabs are being subducted, but later studies have proposed that it also occurs in other arc settings where unusual tectonic conditions can lower the solidus of older slabs. Currently, ada- kite covers a range of arc rocks ranging from pristine slab melt, to adakite-peridotite hybrid melt, to melt derived from peridotite metasomatized by slab melt. Adakite studies have generated some confusions because (1) the definition of adakite combines com- positional criteria with a genetic interpretation (melt- ing of subducted basalt), (2) the definition is fairly broad and relies on chemistry as its distinguishing characteristic, (3) the use of high pressure melting experiment results on wet basalts as unequivocal proofs of slab melting and (4) the existence of ada- kitic rocks with chemical characteristics similar to adakites but are clearly unrelated to slab melting. Other studies have shown that adakitic rocks and a number of the previously reported adakites are pro- duced through melting of the mafic lower crust or ponded basaltic magma, high-pressure crystal frac- tionation of basaltic magma and low-pressure crystal fractionation of basaltic magma plus magma mixing processes in both arc or non-arc tectonic environ- ments. Despite the confusing interpretations on the petrogenesis of adakite and adakitic rocks, their in- vestigations have enriched our understanding of material recycling at subduction zones, crustal evolu- tionary processes and economic mineralization.

埃达克岩(adakite)最初是指由消减板片玄武岩物质熔融形成的富硅、富钠、高Sr/Y和La/Yb比值的弧火山熔岩。它通常产在会聚带,这个部位的年轻的、因而仍然是热的大洋板片正在发生俯冲消减。富铌的岛弧玄武岩则是中等到高碱的镁铁质熔岩,它们相对于正常的岛弧玄武岩含有较多的高场强元素(HFSE)。这些玄武岩通常与埃达克岩共生,而这一组合一直被用于论证他们的高HFSE含量是因为他们的地幔源区受到板片来源的熔体的交代。先前的区域研究表明,南菲律宾是埃达克岩和富铌岛弧玄武岩的一个典型产地。然而最近的详细研究显示,尽管该地区的一些岛弧火山岩是类埃达克岩的,但是它们很可能是来自地幔楔的母岩浆的分异作用的产物,而这里的地幔楔主要是受沉积来源的成分交代的,此外,菲律宾南部最典型的富铌熔岩中HFSE的富集,也很有可能是起因于似乎是西太平洋边缘特有的富集地幔组分的熔融。这些结果提出了如下问题:南菲律宾是否存在真正的板片来源的熔体?这里的富铌岛弧熔岩是否起因于地幔楔被这种熔体交代?

埃达克岩最初是用来定义那些富硅、高Sr/Y和La/Yb的源于俯冲带玄武质洋壳部分熔融形成的火山岩和侵入岩.最初,人们认为埃达克岩仅形成在年青且尚未冷却的大洋板块俯冲会聚带,但随后的研究表明埃达克岩也可以形成于岛弧的一些特殊环境,在这里某些异常构造条件可降低古老板片的熔融温度.目前认为,埃达克岩涵盖了一系列的岛弧火山岩,包括原生俯冲洋壳熔体,埃达克岩-橄榄岩混合熔体以及源于板块熔体交代后地幔楔橄榄岩的熔融产物.近年来埃达克岩的研究产生了一些让人困惑的地方,其原因包括:(1)埃达克岩定义相当宽泛,并依化学特征与其他岩石相区别;(2)将含水体系下玄武岩的高压熔融实验结果作为板块熔融存在的确凿证据;而且(3)存在有与板块熔融无关的埃达克质岩.近期研究表明,埃达克质岩和许多曾被认为是埃达克岩的岩石在岛弧和非岛弧环境下均可形成,主要通过以下几种机制:镁铁质下地壳的分熔或直接是幔源低侵岩浆;高压下玄武质岩浆的结晶分异;低压下玄武岩浆的结晶分异加上相关的岩浆混合过程.这些机制在岛弧环境或非岛弧环境都有可能.尽管对埃达克岩和埃达克质岩的成因解释比较混乱,但对这些岩石的研究丰富了我们对俯冲带环境中物质循环、地壳演化和成矿作用的理解.

This paper reports on the writing of long period gratings （LPGs） in a six-ring pure silica solid core, and large mode area photonic crystal fiber （fiber core diameter p = 10.1 μm） using a CO2 laser system, and the characterization of their strain and temperature sensitivities. Temperature and strain sensitivities in the order of-19.6pm/℃ and -88 pm/με, respectively, were obtained, which were comparable or surpassed values of the similar photonic crystal fiber （PCF）-based LPG or sensor configurations found in the literature.
