查询词典 zircon

Sapphire from Shandon and Hainan commonly have the reaction border, we found out this reaction border enriched with Fe,Mg,and K by testing its components; We also studied the inclusion in the sapphire, and found many KC1 crystal grain with variety of size, a melt inclusion enriched with K,Si, is also found, this may suggest an assimilationary-magmatic course; Besides that, another minerl inclusions such as enstenite, magnetite, chromite, zircon are also found.

观察到了山东、海南蓝宝石普遍存在的反应边，并测试了反应边的成分，证实其以富Fe，Mg，和K为特征；研究了蓝宝石里面的包体，发现蓝宝石里面存在着大小不等的KCl的结晶颗粒，还发现了富K富Si的熔浆包裹体，说明其形成过程中有同化混染的贡献；此外还发现了斜方辉石，磁铁矿，铬铁矿，锆石的包体矿物。

By measuring the relative abundance of two types of uranium and lead in a zircon, geologists can determine old it is.

通过测量相对两种铀和铅的锆、据地质学家能确定旧。

Australia is the major producer of coal,alumina, bauxite, diamonds, titanium minerals and zircon and ranks second in the world in iron ore, mined lead and uranium.

澳大利亚主要煤碳，氧化铝，铝矾土，钻石，钛矿物质和锆石的生产者和位居第二在世界上在铁矿石内，开采引起和铀。

Other alternate clear/white stones are Zircon, Cubic Zirconia, and White Sapphire.

其他候补清晰/白色的石块，锆石，立方氧化锆和白宝石。

Zircon, white sapphire, topaz and quartz are natural minerals that can be nearly colourless and used as natural diamond substitutes.

锆、白宝石、黄玉、天然石英矿，都可以作为天然钻石几乎无色代用品。

Available good quality age dates and zircon Hf isotopic data suggest that the northern parts of the Gangdese experienced a zonal magmatic flareup with strong input of mantlederived materials at ~110 Ma.

已有高质量年龄数据和锆石Hf同位素指示冈底斯带中北部地区在大约110 Ma发生了带状岩浆大爆发并伴随着幔源物质显著增加。

These data indicate that Group B zircon grains are captured ones. It is inferred that the Baiceng basic-ultrabasic pluton originated from a mixed melting between an enriched lithospheric mantle and the continental crust rock formed in 409～450 Ma, responding to an extension of lithosphere at 84 Ma or so. This induced the upwelling of asthenospheric mantle.

据此认为84 Ma左右由于华南岩石圈伸展，软流圈地幔上涌，导致岩石圈富集地幔部分熔融，熔体上升过程中与409～450 Ma左右形成的少量地壳岩石发生混染，随后快速侵位冷凝而形成基性_超基性岩墙。

The data show the following ages: 1894±17 Ma and 1847±59 Ma for garnet pyroxenite of the Tiantangshan Group complex, indicating a Paleoproterozoic age; 1462±28 Ma for the metabasic volcanic rocks of the Yunkai Group complex, indicating the presence of fragments of the Meso- and Neoproterozoic oceanic crust in the Yunkai area; 906±24 Ma for the granitic gneiss intrusion is, which should be the product of the global Grenville 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.

获得天堂山岩群石榴辉石岩的形成年龄为1894Ma±17Ma和1847Ma±59Ma，表明其时代为古元古代；云开岩群洋中脊型变质基性火山岩的喷发年龄为1462Ma±28Ma，证明该地区存在中元古代的古洋壳残片；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。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
