detrital zircon
    (2) the captured sedimentary detrital zircon has an appearance 207Pb/208Pb age of 1823±68Ma, suggesting that the basal Changcheng System be younger than 1823Ma;
    (2)捕获锆石,多为原碎屑锆石,较年轻的一种捕获锆石的207Pb/206Pb表面年龄为1823±68Ma,这限定了长城系底界年龄应新于1823Ma;
    Six detrital zircon grains from the Proterozoic Yongning Formation were measured using this method and ~(207)Pb/~(206)Pb ages of 1965~2590 Ma were obtained.
    应用该方法测定了元古代永宁组沉积岩的碎屑锆石,获得6颗锆石的207Pb/206Pb年龄值为1 965~2 590 Ma。

    The detrital zircons from the sedimentary rocks were dated through SHRIMP and LA-ICP-MS. The result shows that the detrital zircon U-Pb ages concentrate in 1400 to 600Ma, especially 900-700 Ma,which was the most intensive crustal growth stage in western margin of the Yangtze block. But, tectonic and magmatic events of 1000-700Ma have not been identified yet in North China block.
    通过SHRIMP和LA-ICP-MS对研究区碎屑锆石进行了U-Pb定年研究,分析结果表明锆石U-Pb年龄集中于1400-600Ma,特别是900-700Ma,这一时间段正是扬子板块西缘强烈增生的主要阶段,而华北板块没有相应的年龄记录。
    In the detrital zircon sample FH4, which was collected from lower sandstones of the Fanghushan Formation, the oldest sedimentary strata of the Hefei Basin. HP-UHP mineral inclusions such as coesite, omphacite, phengite and melt inclusions, and other minerals like apatite, quartz, feldspar, white micas were identified by means of micro-laser Raman spectrometer and electron probe.
    防虎山组的下部砂岩地层是合肥盆地最古老的中生代沉积地层,在样品FH4中选出了碎屑锆石,通过显微激光拉曼光谱、电子探针的研究发现,锆石中含有柯石英、绿辉石、多硅白云母等典型的高压超高压(HP UHP)矿物包裹体、熔体玻璃包裹体以及磷灰石、石英、斜长石、白云母等矿物包裹体。
    906±24 Ma for the granitic gneiss intrusion is, which should be the product of the global Grenville (Sibaoan) collisional orogeny occurring around 1000 Ma BP. In addition, an inherited detrital zircon age of 2702±13 Ma was also obtained, which is the oldest age in the Yunkai area and even in Cathaysia, proving the presence of Neoarchean continental crustal material in Cathaysia.
    获得花岗质片麻岩的侵入年龄为906Ma±24Ma,应为1000Ma前后发生的全球性Grenville期(四堡期)造山作用的产物,并获得2702Ma±13Ma的继承碎屑锆石年龄,这是云开地区乃至华夏古陆目前获得的最古老年龄,证明华夏古陆曾存在新太古代陆壳物质。
    Detrital zircon of 4100 Ma was discovered, using SHRIMP U-Pb dating, in quartzite in Burang, Tibet.
    在西藏普兰县石英岩中,利用SHRIMPU-Pb法测年发现4.1Ga碎屑锆石
    In this study, Nd isotopic compositions and ages of detrital zircon of schists from the Haizhou Group in the southern part of the Sulu terrain are presented. Detrital zircon gains of three schist samples collected from the Yuntai Formation of the upper Haizhou Group yielded ages clustering around 740 to 800 Ma.
    采用单颗粒锆石U-Pb同位素稀释法和蒸发法定年,获得来自苏鲁地体南部海州群上部云台组的3个云母石英片岩样品的碎屑锆石年龄,且集中于800~740Ma之间。
    U-Pb isotopic ages of 61 detrital zircon grains from the sillimanite-biotite-quartz schist of the Qinling Group in the North Qinling metamorphic terrane are reported in this paper. Of the 61 zircon grains, 15 were measured by SHRIMP Ⅱ, and 46 by LA-ICPMS.
    报道了北秦岭地块中秦岭岩群夕线黑云石英片岩61个碎屑锆石测点的207Pb/206Pb年龄测试结果,其中15个测点在SHRIMPⅡ上进行,46个测点来自LA-ICPMS的测定结果。
    3.8 Ga detrital zircon in the North China craton by means of SHRIMP U-Pb da-ting,the question has cropped up whether the Yangtze craton,one of the two major blocks constituting the basement of China conti-nent,also contains Early Archean crustal relicts.
    自3.8 Ga 的碎屑锆石在华北板块被发现后,关于扬子板块是否也存在早太古代的地壳物质成为众人争论的热点之一。
