黄铁矿Rb-Sr等时线年龄与花岗闪长岩体的单颗粒锆石U-Pb年龄十分一致，表明矿床的形成与岩体有密切的联系，花岗闪长岩体提供了矿床形成所需要的能量和部分流体，而地层也提供了部分成矿物质。

Coincident biotite 40Ar/39Ar ages yield in rocks in the south of Yadong and in the high-pressure granulite shows that on the section of Yadong-ZhergerLa, rocks were cooled to 320℃contemporarily.

在亚东县城以南的两处花岗质片麻岩中，锆石U-Pb年龄分别为1149和474 Ma，为原岩和泛非变质事件的年龄，黑云母单次全熔40Ar/39Ar年龄为11.3和11.0 Ma，磷灰石裂变径迹年龄分别为7和8 Ma。

These results indicate that both the second type leucosome in the biotite gneisses and the first type leucosome were produced synchronously in the Paleoproterozoic granulite-facies metamorphism, and that both the melt-derived and the metamorphic Paleoproterozoic zircons suffered significant lead-loss in the Triaasic, suggesting that both felsic granulite and biotite gneisses be responses to the Triassic deep subduction event.

这表明，第二类浅色体和第一类浅色体都是古元古代麻粒岩相变质作用同期深熔产物。古元古代熔体结晶和变质结晶锆石在三迭纪发生了严重的放射性成因铅丢失，可反映长英质麻粒岩和黑云母片麻岩都响应了三迭纪深俯冲事件。

Including zircon, quartz, clay and halite salt crystals, formed during this early period of mineral evolution.

这句语序换一下包括锆石、石英、黏土、岩盐晶体在内的形成于矿物进化早期的几百种矿物。

High-fashion Bangles can be a heavy cuff adorned with genuine gemstones or Cubic Zirconia, finely etched or cut through with a precise design.

高时尚手镯可以是一个沉重的袖口饰以真正的宝石或锆石，细切蚀刻或通过精确的设计。

Based on the zircon saturation temperature and hornblende geobarometer estimation, the crystallization temperature and pressure of enclaves and hosting granite are very close, in the range of 793~824℃ and 3.5~5.1Kb, respectively.

用锆石饱和温度和角闪石成分估算了包体和寄主花岗岩结晶的温度和压力表明，它们的结晶温度和压力条件相近，分别在793~824℃和(3.5~5.1)/10^8Pa范围内。

The depth of emplacement of this granite body obtained by the hornblende geobarometer is up to 24.5 km.

摘 要：锆石U-Pb年龄表明鄂东月山岩体是一个古老花岗岩经后期重熔并于燕山中期(139Ma)侵入的花岗岩体，角闪石压力计得出侵位深度达24.5km。

However , it is also important to know that zircon is not the oft seen diamond imposter , cubic zirconia

第一次正式使用" zircon "是在1783年，用来形容来自斯里兰卡的绿色锆石晶体。

Through U-Pb isotope age study in sheeted dike complex, has gained the isochrone age is114-133Ma.The age is early cretaceous,which indicates the time of formation of sheeted dikecomplex.

另外，在该蛇绿岩套中的岩墙群进行了单颗粒锆石U－Pb同位素测年，获得的表面年龄值为 114－133Ma 之间，时代为早白垩世，基本反映了席状岩墙群的成岩年龄。

The differential exhumation caused by the NNE-trending faults probably continued all the way from the 180℃isothermal surface, through 110℃isothermal surface to the 70℃isothermal surface. At 90Ma, Dabie orogen"s average height of topography, compared with the current sea level, reached 1.45 km (when geothermal gradient is chosen as 25℃/km) or 1.75 km (when geothermal gradient is chosen as 20℃/km), which is 4(when geothermal gradient is chosen as 25℃/km) or 5(when geothermal gradient is chosen as 20℃/km) times of the height of today"s surface topography in simulated region.

这种由于NNE向断裂系引发的差异推隆剥露，可能从等温面180℃锆石(U-Th／He的封闭温度、经过110℃(磷灰石裂变径迹的退火温度)一直延续到70℃等温面磷灰石(U-Th／He的封闭温度大别造山带90Ma时与现今海平面相比地形平均高度可达1.45km(地温梯度取25℃／km时)或1.75km(地温梯度取20℃／km时)，是现今模拟区域地形平均高度的4倍(地温梯度取25℃／km时)或5倍(地温梯度取20℃／km时)。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
