锆石

Our survey suggested that :(1)the way in which zirconia is added has significant impact to the property of ceramic powders. The flexural strength of the ceramic powders produced by the mix of ZrO2 and leucite crystal is much lower than that of ceramic powders produced by solid phase reaction.

氧化锆-白榴石基烤瓷粉的研究表明：(1)氧化锆的添加方式对瓷粉的性能影响很大，氧化锆与合成的白榴石晶体混合所得的瓷粉的弯曲强度大大低于一次固相反应合成的氧化锆-白榴石烤瓷粉，其弯曲强度甚至还不如没有添加氧化锆的瓷粉。

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 calculating the ratio of uranium to lead, they determined that a dozen of the grains were very old indeed.

通过计算进入的铀的含量，他们确定了十二个锆石颗粒的确非常古老。

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。

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。

The U-P dating data of zircons imply that topography was low in the west and high in the east of East China Sea shelf during the development of Eogene basin.

根据上述砂岩锆石U-P年龄，可以推测古近纪东海陆架盆地发育过程中，东海陆架东部地势较高。

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。
