查询词典 spinel ruby

A light silver-white ductile bivalent metallic element; in pure form it burns with brilliant white flame; occurs naturally only in combination (as in magnesite and dolomite and carnallite and spinel and olivine).

轻而软的银白色二价金属元素，纯净状态下燃烧会发出明亮白光，仅天然存在于化合物中（如菱镁矿、白云石、光卤石、尖晶石、橄榄石）。

The addition of cerium can inhibit the formation of spinel phase and make the CuO disperse well.

但铈的引入会使氧化铜分散度增大，同时抑制尖晶石相的生成。

Well-documented Lu-Hf isotope data from the oceanic basalts show that,the starting area of magma melting for the MORBs derived from the DMM component would be in the the depth of garnet peridotite,i.e.at the depth of 80―90 km instead of less than 60 km,which is at the depth of spinel peridotite as proposed early.The HIMU component,which is characterized by its high rediogenic lead,is refered as a special mantle component differentiated at some time in geological history from the lower mantle.A correlation study of Hf-Nd isotope between the chondrite and oceanic basalts implies that no isolated primitive mantle might have remained.

大量的大洋玄武岩Lu-Hf同位素研究表明：具亏损地幔端元来源的洋中脊玄武岩岩浆部分熔融的初熔区位于石榴石稳定场深度，即深度为80-90 km的石榴石二辉橄榄岩地幔，而不是原来所认为的尖晶石二辉橄榄岩区(深度小于60 km)；以高放射成因Pb为特征的高U地幔端元应代表了下地幔物质在某一特定时期发生分异作用的结果；球粒陨石与大洋玄武岩Hf同位素对比研究表明，没有原始地幔物质能保留至今的迹象。

Therefore, the intergrowth texture of Cr-spinel and pyroxene can be an important indicator for podiform chromite exploration.
