查询词典 metasomatism

The reasons for higher initial Sr isotopic ratios are probably that there is enriched mantle endmember and the ophiolite underwent metasomatism of fluid from the melting of terrestrial matter in the course of formation.

ISr值偏高可能是存在富集型地幔源区和蛇绿岩形成过程中经受了地幔流体的交代作用引起的。

Or was migmatite by metasomatism.

或是交代成因的混合岩。

This suggests that the secondary orthopyroxene formed at the expense of olivine and clinopyroxene during the metasomatism by an evolved Tirich melt.

与含石榴石橄榄岩中的斜方辉石相比，这种次生的斜方辉石以高TiO2、中等含量的Al2O3以及低Mg＃为特征，表明它是在一种高度分异演化的富Ti熔体交代作用下通过消耗橄榄石和单斜辉石方式形成的。

It is believed that the iron, gold and cobalt ores in Kaxiutata were formed at different stages of the same ore_forming event, and the magnetite ores are products of the contact metasomatism between the magma and the strata, while the enrichment of the gold and cobalt resulted from the subsequent sulfide deposition at the meso_hypothermal stages.

卡休他他铁、金和钴矿的形成可能是同一成矿事件中不同阶段的产物，磁铁矿体属于早期岩浆气液阶段接触交代的产物，而钴和金的富集则可能是稍后的中高温热液阶段的产物。

The variations of Cr# in spinel and Ti in pyroxene suggest that the Daba-Xiugugabu peridotite had a history of complex melting and an impress of mantle metasomatism. The processes of formation of the peridotites possibly include a transition from a tectonic setting to another.

尖晶石中Cr及辉石中Ti的广泛变化表明它们具有复杂的熔融历史及地幔交代作用的印记，其形成过程可能经历了两种构造环境的转变。

Mantle metasomatism not only change chemical texture of the upper mantle, but also results in increase of heat flux, decrease of density, expansion of volume, and lowering of solidus of metasomatic mantle.

地幔交代作用不仅改变了上地幔的化学结构，而且导致交代地幔热流升高、密度降低、体积膨大、固相线下降。

The Kaxiutata iron deposit belongs genetically to the contact metasomatism or skarn type.

因此，卡休他他铁矿床属于接触交代型或矽卡岩型。

The mantle metasomatism in western Shandong could be subdivided into two stages, i.e. early metasomatic event with interstitial phlogopite and late metasomatic event with orthopyroxene vein or orthopyroxene+phlogopite vein.

鲁西区地幔交代作用应有两期，即早期的填隙型金云母和晚期的斜方辉石脉或斜方辉石+金云母脉体的形成，早期交代介质为富含CO〓和H〓O的熔体，晚期交代介质为富硅质的熔体。

The lower lithospheric mantle in western Shandong could be composed of Group Ⅰ inclusions which were subjected to orthopyroxene vein or orthopyroxene+ phlogopite vein and disseminated phlogopite metasomatism.

鲁西区软流圈的顶部，即岩石圈地幔的底部应为一套组Ⅰ型包体，它们存在斜方辉石交代脉体和斜方辉石+金云母的交代脉体以及弥漫型金云母；向上(约43～57km±)为一套堆积岩。

Through analysis of the experimental data about ultrapotassic rocks, typeI ultrapotassic rocks came from the source region of phlogopite harzburgite that had undergone metasomatism of fluid enriched in silica and potassium; while the source region of typeⅢ potassicultrapotassic volcanics is carbonated peridotite mantle bearing potassic amphibole.

综合超钾质岩石的实验资料，可知区内I型超钾质岩的源区以富硅、富钾流体交代形成的金云母方辉橄榄岩为主；Ⅲ型钾质超钾质岩浆源区则以斜辉橄榄岩地幔为主。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
