查询词典 chromite

The analysis of the chemical composition of mineral inclusions including olivine, garnet, clinopyroxene, and chromite from Mengyin and Fuxian diamonds, reveals that the major elements of mineral inclusions in diamond show characters with high depletion in basaltic composition.

对山东蒙阴、辽宁复县两地金刚石中包裹体矿物包括橄榄石、石榴石、单斜辉石和铬铁矿的化学成分进行了深入分析，金刚石包裹体矿物的主量元素显示华北地台至少在古生代金伯利岩侵位时具高度亏损玄武质的难熔克拉通岩石圈地幔特征。

The chromite deposits in the Muskox Complex occur only in feldspathic peridotite.

在穆斯科克斯杂岩体中，铬铁矿矿层仅产于长石质橄榄岩中。

Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20～40kb (equivalent to 65～130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

除金刚石中的辉石温压投点落于40m W/m〓占地温线上外，捕虏体及捕虏晶中石榴石，铬尖晶石及单斜辉石的投点均偏离该地温线，显示较高的地温特点，而且捕虏体及捕虏晶的压力范围多在20-40kb(相当于65-130km)间，该深度范围内地幔的交代作用特别发育，如蒙阴大量发育的沂蒙矿、钛钾铬石等就发育于该深度范围，世界范围内不含金刚石的高钙方辉橄榄岩、二辉橄榄岩、异剥橄榄岩也分布于该区中，一方面表明捕虏体的主要取样位置已不在金刚石稳定区中，另一方面也表明金刚石稳定的橄榄岩环境，在金伯利岩侵位并捕虏他们时已发现了明显的改造，这种改造作用主要是通过长期的熔流体与先存的橄榄岩相互作用的结果。

The major mechanism of formation of the ophiolites and the podiform chromite diposits in the Western Zhungeer area includes partial melting of the primary pyrolite and differentiation of the melt-out materials after they intruded. The differences between the two ophiolite types are related to the degree of partial melting of the pyrolite and depth of formation of magma chambers as well as oxidation state of the magmas.

对西准噶尔地质条件的分析表明：西准噶尔的蛇绿岩与铬铁矿形成于弧后扩张盆地环境，洋壳形成阶段从晚寒武直至中泥盆统，而盆地沉积阶段则从中奥陶延续到中石炭；洋壳推覆时代不一致，在唐巴勒为早志留，玛依勒山为晚泥盆，达拉布特与和布克赛尔则晚于中石炭。

Coarse-grained pyroxenes commonly contain abundant tiny or needle-like chromite inclusions with orientation,probably due to heavy shock events.

粗粒辉石晶体普遍存在微粒状或细针状铬铁矿，并具有定向分布特征，可能也与强烈的冲击变质有关。

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。
